¿Cuál es la versión C # del InputDialog de VB.net?

¿Cuál es la versión C # de InputBox de VB.net?

Agregue una referencia a Microsoft.VisualBasic, InputBoxestá en el Microsoft.VisualBasic.Interactionespacio de nombres:

using Microsoft.VisualBasic;
string input = Interaction.InputBox("Prompt", "Title", "Default", x_coordinate, y_coordinate);

Solo el primer argumento promptes obligatorio

Para resumirlo:

• No hay ninguno en C # .

• Puede usar el diálogo de Visual Basic agregando una referencia a Microsoft.VisualBasic:

  1. En el Explorador de soluciones , haga clic con el botón derecho en la carpeta Referencias .
  2. Seleccione Agregar referencia ...
  3. En la pestaña .NET (en las versiones más recientes de Visual Studio - pestaña Ensamblaje ) - seleccione Microsoft.VisualBasic
  4. Haga clic en Aceptar

Luego puede usar el código mencionado anteriormente:

string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);

• Escribe tu propio InputBox.
• Usa el de otra persona .

Dicho esto, le sugiero que considere la necesidad de un cuadro de entrada en primer lugar. Los diálogos no siempre son la mejor manera de hacer las cosas y, a veces, hacen más daño que bien, pero eso depende de la situación particular.

Creación dinámica de un cuadro de diálogo. Puedes personalizarlo a tu gusto.

Tenga en cuenta que aquí no hay dependencia externa, excepto winform

private static DialogResult ShowInputDialog(ref string input)
    {
        System.Drawing.Size size = new System.Drawing.Size(200, 70);
        Form inputBox = new Form();

        inputBox.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
        inputBox.ClientSize = size;
        inputBox.Text = "Name";

        System.Windows.Forms.TextBox textBox = new TextBox();
        textBox.Size = new System.Drawing.Size(size.Width - 10, 23);
        textBox.Location = new System.Drawing.Point(5, 5);
        textBox.Text = input;
        inputBox.Controls.Add(textBox);

        Button okButton = new Button();
        okButton.DialogResult = System.Windows.Forms.DialogResult.OK;
        okButton.Name = "okButton";
        okButton.Size = new System.Drawing.Size(75, 23);
        okButton.Text = "&OK";
        okButton.Location = new System.Drawing.Point(size.Width - 80 - 80, 39);
        inputBox.Controls.Add(okButton);

        Button cancelButton = new Button();
        cancelButton.DialogResult = System.Windows.Forms.DialogResult.Cancel;
        cancelButton.Name = "cancelButton";
        cancelButton.Size = new System.Drawing.Size(75, 23);
        cancelButton.Text = "&Cancel";
        cancelButton.Location = new System.Drawing.Point(size.Width - 80, 39);
        inputBox.Controls.Add(cancelButton);

        inputBox.AcceptButton = okButton;
        inputBox.CancelButton = cancelButton; 

        DialogResult result = inputBox.ShowDialog();
        input = textBox.Text;
        return result;
    }

uso

string input="hede";
ShowInputDialog(ref input);

No hay uno Si realmente desea utilizar VB InputBox en C #, puede hacerlo. Simplemente agregue referencia a Microsoft.VisualBasic.dll y la encontrará allí.

Pero sugeriría no usarlo. Es feo y anticuado IMO.

No solo debe agregar Microsoft.VisualBasic a su lista de referencia para el proyecto, sino que también debe declarar 'usar Microsoft.VisualBasic;' así que solo tiene que usar 'Interaction.Inputbox ("...")' en lugar de Microsoft.VisualBasic.Interaction.Inputbox

Devuelve la cadena que ingresó el usuario; cadena vacía si golpean Cancel:

    public static String InputBox(String caption, String prompt, String defaultText)
    {
        String localInputText = defaultText;
        if (InputQuery(caption, prompt, ref localInputText))
        {
            return localInputText;
        }
        else
        {
            return "";
        }
    }

Devuelve Stringcomo un parámetro de referencia , devolviendo truesi golpean OKo falsesi golpean Cancel:

    public static Boolean InputQuery(String caption, String prompt, ref String value)
    {
        Form form;

Agregue referencia Microsoft.VisualBasicy use esta función:

string response =  Microsoft.VisualBasic.Interaction.InputBox("What's 1+1?", "Title", "2", 0, 0);

El último número 2 es una posición X / Y para mostrar el diálogo de entrada.

¿Te refieres a InputBox? Solo mire en el espacio de nombres Microsoft.VisualBasic.

C # y VB.Net comparten una biblioteca común. Si un idioma puede usarlo, también lo puede hacer el otro.

Sin agregar una referencia a Microsoft.VisualBasic:

// "dynamic" requires reference to Microsoft.CSharp
Type tScriptControl = Type.GetTypeFromProgID("ScriptControl");
dynamic oSC = Activator.CreateInstance(tScriptControl);

oSC.Language = "VBScript";
string sFunc = @"Function InBox(prompt, title, default) 
InBox = InputBox(prompt, title, default)    
End Function
";
oSC.AddCode(sFunc);
dynamic Ret = oSC.Run("InBox", "メッセージ", "タイトル", "初期値");

Consulte estos para obtener más información:
ScriptControl
MsgBox en JScript
Input y MsgBox en JScript

.NET 2.0:

string sFunc = @"Function InBox(prompt, title, default) 
InBox = InputBox(prompt, title, default)    
End Function
";

Type tScriptControl = Type.GetTypeFromProgID("ScriptControl");
object oSC = Activator.CreateInstance(tScriptControl);

// https://github.com/mono/mono/blob/master/mcs/class/corlib/System/MonoType.cs
// System.Reflection.PropertyInfo pi = tScriptControl.GetProperty("Language", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.CreateInstance| System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.SetProperty | System.Reflection.BindingFlags.IgnoreCase);
// pi.SetValue(oSC, "VBScript", null);

tScriptControl.InvokeMember("Language", System.Reflection.BindingFlags.SetProperty, null, oSC, new object[] { "VBScript" });
tScriptControl.InvokeMember("AddCode", System.Reflection.BindingFlags.InvokeMethod, null, oSC, new object[] { sFunc });
object ret = tScriptControl.InvokeMember("Run", System.Reflection.BindingFlags.InvokeMethod, null, oSC, new object[] { "InBox", "メッセージ", "タイトル", "初期値" });
Console.WriteLine(ret);

Pude lograr esto codificando el mío. No me gusta extenderme y confiar en grandes bibliotecas para algo rudimentario.

No existe tal cosa: recomiendo escribirlo usted mismo y usarlo cuando lo necesite.
