El problema es que necesito saber si es la versión 3.5 SP 1. Environment.Version()
solo regresa 2.0.50727.3053
.
Encontré esta solución , pero creo que tomará mucho más tiempo del que vale, así que estoy buscando una más simple. ¿Es posible?

Environment.Version()
probablemente solo devuelva la versión del CLR.2.0
incluso si se ejecuta con3.5
Respuestas:
Algo como esto debería hacerlo. Simplemente tome el valor del registro
Para .NET 1-4 :
Framework
es la versión instalada más alta,SP
es el paquete de servicio para esa versión.RegistryKey installed_versions = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP"); string[] version_names = installed_versions.GetSubKeyNames(); //version names start with 'v', eg, 'v3.5' which needs to be trimmed off before conversion double Framework = Convert.ToDouble(version_names[version_names.Length - 1].Remove(0, 1), CultureInfo.InvariantCulture); int SP = Convert.ToInt32(installed_versions.OpenSubKey(version_names[version_names.Length - 1]).GetValue("SP", 0));
Para .NET 4.5+ (de la documentación oficial ):
using System; using Microsoft.Win32; ... private static void Get45or451FromRegistry() { using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\")) { int releaseKey = Convert.ToInt32(ndpKey.GetValue("Release")); if (true) { Console.WriteLine("Version: " + CheckFor45DotVersion(releaseKey)); } } } ... // Checking the version using >= will enable forward compatibility, // however you should always compile your code on newer versions of // the framework to ensure your app works the same. private static string CheckFor45DotVersion(int releaseKey) { if (releaseKey >= 461808) { return "4.7.2 or later"; } if (releaseKey >= 461308) { return "4.7.1 or later"; } if (releaseKey >= 460798) { return "4.7 or later"; } if (releaseKey >= 394802) { return "4.6.2 or later"; } if (releaseKey >= 394254) { return "4.6.1 or later"; } if (releaseKey >= 393295) { return "4.6 or later"; } if (releaseKey >= 393273) { return "4.6 RC or later"; } if ((releaseKey >= 379893)) { return "4.5.2 or later"; } if ((releaseKey >= 378675)) { return "4.5.1 or later"; } if ((releaseKey >= 378389)) { return "4.5 or later"; } // This line should never execute.

?No sé por qué nadie sugirió siguiendo el consejo oficial de Microsoft derecha aquí .
Este es el código que recomiendan. Seguro que es feo, pero funciona.
Para .NET 1-4

Environment.Version()
está dando la respuesta correcta para una pregunta diferente. La misma versión de CLR se usa en .NET 2.0, 3 y 3.5. Supongo que podría consultar el GAC para ver las bibliotecas que se agregaron en cada una de esas versiones posteriores.fuente
2.0
incluso si se ejecuta con3.5
Solía ser fácil, pero Microsoft decidió hacer un cambio radical: antes de la versión 4.5, cada versión de .NET residía en su propio directorio a continuación
C:\Windows\Microsoft.NET\Framework
(subdirectoriosv1.0.3705, v1.1.4322, v2.0.50727, v3.0, v3.5
yv4.0.30319
).Desde la versión 4.5, esto ha cambiado: cada versión de .NET (es decir, 4.5.x, 4.6.x, 4.7.x, 4.8.x, ...) se está instalando en el mismo subdirectorio
v4.0.30319
, por lo que ya no puede compruebe la versión de .NET instalada mirando enMicrosoft.NET\Framework
.Para comprobar la versión .NET, Microsoft ha proporcionado dos scripts de muestra diferentes según la versión .NET que se esté comprobando, pero no me gusta tener dos scripts C # diferentes para esto. Así que intenté combinarlos en uno, aquí está el script
GetDotNetVersion.cs
que creé (y lo actualicé para el marco 4.7.1):using System; using Microsoft.Win32; public class GetDotNetVersion { public static void Main(string[] args) { Console.WriteLine((args != null && args.Length > 0) ? "Command line arguments: " + string.Join(",", args) : ""); string maxDotNetVersion = GetVersionFromRegistry(); if (String.Compare(maxDotNetVersion, "4.5") >= 0) { string v45Plus = GetDotNetVersion.Get45PlusFromRegistry(); if (v45Plus != "") maxDotNetVersion = v45Plus; } Console.WriteLine("*** Maximum .NET version number found is: " + maxDotNetVersion + "***"); } private static string Get45PlusFromRegistry() { String dotNetVersion = ""; const string subkey = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\"; using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey(subkey)) { if (ndpKey != null && ndpKey.GetValue("Release") != null) { dotNetVersion = CheckFor45PlusVersion((int)ndpKey.GetValue("Release")); Console.WriteLine(".NET Framework Version: " + dotNetVersion); } else { Console.WriteLine(".NET Framework Version 4.5 or later is not detected."); } } return dotNetVersion; } // Checking the version using >= will enable forward compatibility. private static string CheckFor45PlusVersion(int releaseKey) { if (releaseKey >= 528040) return "4.8 or later"; if (releaseKey >= 461808) return "4.7.2"; if (releaseKey >= 461308) return "4.7.1"; if (releaseKey >= 460798) return "4.7"; if (releaseKey >= 394802) return "4.6.2"; if (releaseKey >= 394254) return "4.6.1"; if (releaseKey >= 393295) return "4.6"; if ((releaseKey >= 379893)) return "4.5.2"; if ((releaseKey >= 378675)) return "4.5.1"; if ((releaseKey >= 378389)) return "4.5"; // This code should never execute.

En mi máquina sale:
Lo único que debe mantenerse a lo largo del tiempo es el número de compilación una vez que salga una versión .NET superior a 4.7.1; eso se puede hacer fácilmente modificando la función
CheckFor45PlusVersion
, debe conocer la clave de lanzamiento para la nueva versión y luego puede agregarlo. Por ejemplo:if (releaseKey >= 461308) return "4.7.1 or later";
Esta clave de lanzamiento sigue siendo la más reciente y válida para la actualización Fall Creators de Windows 10. Si todavía está ejecutando otras versiones de Windows (más antiguas), hay otra según esta documentación de Microsoft:
Entonces, si lo necesita también, tendrá que agregar
if (releaseKey >= 461310) return "4.7.1 or later";
a la parte superior de la función
CheckFor45PlusVersion
. Asimismo, funciona para versiones más nuevas. Por ejemplo, recientemente agregué el cheque para 4.8. Puede encontrar esos números de compilación generalmente en Microsoft.Nota: No necesita que Visual Studio esté instalado, ni siquiera PowerShell; puede usarlo
csc.exe
para compilar y ejecutar el script anterior, que he descrito aquí.Actualización: la pregunta es sobre .NET Framework, en aras de la integridad, me gustaría mencionar cómo consultar la versión de .NET Core también; en comparación con lo anterior, eso es fácil: abra un shell de comandos y escriba:
y también enumerará el número de versión de .NET Core, la versión de Windows y las versiones de cada DLL de tiempo de ejecución relacionado. Salida de muestra:
Nota que
si solo necesita el número de versión sin toda la información adicional, puede usar
dotnet --version
.en una PC con Windows de 64 bits , es posible instalar la versión x86 junto con la versión x64 de .NET Core. Si ese es el caso, solo obtendrá la versión que aparece primero en la variable de entorno
PATH
. Eso es especialmente importante si necesita mantenerlo actualizado y desea conocer cada versión. Para consultar ambas versiones, use:En el ejemplo anterior, ambos son iguales, pero si olvidó actualizar ambas instancias, ¡puede obtener resultados diferentes! Tenga en cuenta que
Program Files
es para la versión de 64 bits yProgram Files (x86)
es la versión de 32 bits .Actualización: si prefiere mantener los números de compilación en una lista en lugar de en una cascada de declaraciones if (como sugirió Microsoft), entonces puede usar este código para
CheckFor45PlusVersion
:private static string CheckFor45PlusVersion(int releaseKey) { var release = new Dictionary<int, string>() { { 378389, "4.5" }, { 378675, "4.5.1" }, { 379893, "4.5.2" }, { 393295, "4.6" }, { 394254, "4.6.1" }, { 394802, "4.6.2" }, { 460798, "4.7" }, { 461308, "4.7.1" }, { 461808, "4.7.2" }, { 528040, "4.8 or later" } }; int result = -1; foreach(var k in release.OrderBy(k=>k.Key)) { if (k.Key <= releaseKey) result = k.Key; else break; }; return (result > 0) ? release[result] : "No 4.5 or later version detected"; }

AFAIK no hay un método integrado en el marco que le permita hacer esto. Puede consultar esta publicación para obtener una sugerencia sobre cómo determinar la versión del marco leyendo los valores del registro de Windows.

Esta clase permite que su aplicación envíe un mensaje de notificación elegante en lugar de bloquearse y quemarse si no puede encontrar la versión de .NET adecuada. Todo lo que necesita hacer es esto en su código principal:
[STAThread] static void Main(string[] args) { if (!DotNetUtils.IsCompatible()) return; . . . }
Por defecto, toma 4.5.2, pero puede modificarlo a su gusto, la clase (no dude en reemplazar MessageBox con Console):
Actualizado para 4.8:
public class DotNetUtils { public enum DotNetRelease { NOTFOUND, NET45, NET451, NET452, NET46, NET461, NET462, NET47, NET471, NET472, NET48, } public static bool IsCompatible(DotNetRelease req = DotNetRelease.NET452) { DotNetRelease r = GetRelease(); if (r < req) { MessageBox.Show(String.Format("This this application requires {0} or greater.", req.ToString())); return false; } return true; } public static DotNetRelease GetRelease(int release = default(int)) { int r = release != default(int) ? release : GetVersion(); if (r >= 528040) return DotNetRelease.NET48; if (r >= 461808) return DotNetRelease.NET472; if (r >= 461308) return DotNetRelease.NET471; if (r >= 460798) return DotNetRelease.NET47; if (r >= 394802) return DotNetRelease.NET462; if (r >= 394254) return DotNetRelease.NET461; if (r >= 393295) return DotNetRelease.NET46; if (r >= 379893) return DotNetRelease.NET452; if (r >= 378675) return DotNetRelease.NET451; if (r >= 378389) return DotNetRelease.NET45; return DotNetRelease.NOTFOUND; } public static int GetVersion() { int release = 0; using (RegistryKey key = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32) .OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\")) { release = Convert.ToInt32(key.GetValue("Release")); } return release; } }
Fácilmente ampliable cuando agreguen una nueva versión más adelante. No me molesté con nada antes de la 4.5, pero entiendes la idea.

Tuve una situación en la que mi biblioteca de clases .NET 4.0 podría llamarse desde un ensamblado de .NET 4.0 o una versión superior.
Una llamada a un método específico solo funcionaría si se ejecutara desde un ensamblado 4.5+.
Para decidir si debo llamar al método o no, necesitaba determinar la versión actual del marco de ejecución y esta es una solución bastante buena para eso
var frameworkName = new System.Runtime.Versioning.FrameworkName( AppDomain.CurrentDomain.SetupInformation.TargetFrameworkName ); if (frameworkName.Version >= new Version(4, 5)) { // run code }

Gracias por esta publicación que fue bastante útil. Tuve que modificarlo un poco para verificar el marco 2.0 porque la clave de registro no se puede convertir directamente en un doble. Aquí está el código:

Intenté combinar todas las respuestas en un solo todo.
Utilizando:
NetFrameworkUtilities.GetVersion()
devolverá la versión actualmente disponible de .NET Framework en este momento o nula si no está presente.Este ejemplo funciona en las versiones 3.5+ de .NET Framework. No requiere derechos de administrador.
Quiero señalar que puede verificar la versión usando los operadores <y> así:
var version = NetFrameworkUtilities.GetVersion(); if (version != null && version < new Version(4, 5)) { MessageBox.Show("Your .NET Framework version is less than 4.5"); }
Código:
using System; using System.Linq; using Microsoft.Win32; namespace Utilities { public static class NetFrameworkUtilities { public static Version GetVersion() => GetVersionHigher4() ?? GetVersionLowerOr4(); private static Version GetVersionLowerOr4() { using (var key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP")) { var names = key?.GetSubKeyNames(); //version names start with 'v', eg, 'v3.5' which needs to be trimmed off before conversion var text = names?.LastOrDefault()?.Remove(0, 1); if (string.IsNullOrEmpty(text)) { return null; } return text.Contains('.') ? new Version(text) : new Version(Convert.ToInt32(text), 0); } } private static Version GetVersionHigher4() { using (var key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full")) { var value = key?.GetValue("Release"); if (value == null) { return null; } // Checking the version using >= will enable forward compatibility, // however you should always compile your code on newer versions of // the framework to ensure your app works the same. var releaseKey = Convert.ToInt32(value); if (releaseKey >= 461308) return new Version(4, 7, 1); if (releaseKey >= 460798) return new Version(4, 7); if (releaseKey >= 394747) return new Version(4, 6, 2); if (releaseKey >= 394254) return new Version(4, 6, 1); if (releaseKey >= 381029) return new Version(4, 6); if (releaseKey >= 379893) return new Version(4, 5, 2); if (releaseKey >= 378675) return new Version(4, 5, 1); if (releaseKey >= 378389) return new Version(4, 5); // This line should never execute.

Actualice con .NET 4.6.2. Verifique el valor de lanzamiento en el mismo registro que en las respuestas anteriores:
RegistryKey registry_key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full"); if (registry_key == null) return false; var val = registry_key.GetValue("Release", 0); UInt32 Release = Convert.ToUInt32(val); if (Release >= 394806) // 4.6.2 installed on all other Windows (different than Windows 10) return true; if (Release >= 394802) // 4.6.2 installed on Windows 10 or later return true;

Puede obtener una cadena útil sin tener que tocar el registro o ensamblajes de referencia que pueden o no cargarse. mscorlib.dll y otros ensamblados del sistema tienen AssemblyFileVersionAttribute definido, y parece ser único para cada versión de .NET, según los ensamblados de referencia proporcionados con Visual Studio.
string version = (typeof(string).Assembly .GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false) .FirstOrDefault() as AssemblyFileVersionAttribute)?.Version;
La versión 4.5 está un poco fuera de lugar, porque está marcada como 4.0 en esa versión, pero la 4.6 en adelante parece tener la versión menor que coincide al menos. Hacerlo de esta manera parece ser más una prueba de futuro que depender de alguna clave de registro del instalador y tener que comparar con un conjunto fijo de valores.
Encontré los ensamblajes de referencia aquí:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework
De donde obtuve las siguientes versiones:
4.0 = 4.0.30319.1 4.5 = 4.0.30319.18020 4.5.1 = 4.0.30319.18402 4.5.2 = 4.0.30319.34211 4.6 = 4.6.81.0 4.6.1 = 4.6.1055.0 4.7.2 = 4.7.3062.0 4.8 = 4.8.3761.0
