Add a reference to Microsoft.VisualBasic, InputBoxis in the Microsoft.VisualBasic.Interactionnamespace:

在命名空间中添加对Microsoft.VisualBasic,的引用：InputBoxMicrosoft.VisualBasic.Interaction

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

Only the first argument for promptis mandatory

只有第一个参数 forprompt是强制性的

There is no such thing: I recommend to write it for yourself and use it whenever you need.

没有这样的东西：我建议自己编写它，并在需要时使用它。

回答by Joel Coehoorn

You mean InputBox? Just look in the Microsoft.VisualBasic namespace.

你是说输入框？只需查看 Microsoft.VisualBasic 命名空间。

C# and VB.Net share a common library. If one language can use it, so can the other.

C# 和 VB.Net 共享一个公共库。如果一种语言可以使用它，那么另一种语言也可以。

There isn't one. If you really wanted to use the VB InputBox in C# you can. Just add reference to Microsoft.VisualBasic.dll and you'll find it there.

没有一个。如果你真的想在 C# 中使用 VB InputBox，你可以。只需添加对 Microsoft.VisualBasic.dll 的引用，您就会在那里找到它。

But I would suggest to notuse it. It is ugly and outdated IMO.

但我建议不要使用它。这是丑陋和过时的 IMO。

Add reference to Microsoft.VisualBasicand use this function:

添加Microsoft.VisualBasic对此函数的引用并使用：

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

The last 2 number is an X/Y position to display the input dialog.

最后 2 个数字是显示输入对话框的 X/Y 位置。

To sum it up:

把它们加起来：

• There is none in C#.

• You can use the dialog from Visual Basic by adding a reference to Microsoft.VisualBasic:

  1. In Solution Explorerright-click on the Referencesfolder.
  2. Select Add Reference...
  3. In the .NETtab (in newer Visual Studio verions - Assemblytab) - select Microsoft.VisualBasic
  4. Click on OK

• 有没有在C＃ 。

• 您可以通过添加对 Microsoft.VisualBasic 的引用来使用 Visual Basic 中的对话框：

  1. 在解决方案资源管理器中，右键单击References文件夹。
  2. 选择添加引用...
  3. 在.NET选项卡中（在较新的 Visual Studio 版本 -程序集选项卡中） - 选择Microsoft.VisualBasic
  4. 点击确定

Then you can use the previously mentioned code:

然后你可以使用前面提到的代码：

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

• Write your own InputBox.
• Use someone else's.

• 编写自己的输入框。
• 用别人的。

That said, I suggest that you consider the need of an input box in the first place. Dialogs are not always the best way to do things and sometimes they do more harm than good - but that depends on the particular situation.

也就是说，我建议您首先考虑输入框的需要。对话并不总是最好的做事方式，有时它们弊大于利 - 但这取决于特定情况。

Not only should you add Microsoft.VisualBasic to your reference list for the project, but also you should declare 'using Microsoft.VisualBasic;' so you just have to use 'Interaction.Inputbox("...")' instead of Microsoft.VisualBasic.Interaction.Inputbox

您不仅应该将 Microsoft.VisualBasic 添加到项目的参考列表中，还应该声明“使用 Microsoft.VisualBasic；” 所以你只需要使用 'Interaction.Inputbox("...")' 而不是 Microsoft.VisualBasic.Interaction.Inputbox

Returns the string the user entered; empty string if they hit Cancel:

返回用户输入的字符串；如果它们命中，则为空字符串Cancel：

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

Returns the Stringas a refparameter, returning trueif they hit OK, or falseif they hit Cancel:

将 返回String为ref参数，true如果它们击中OK或false击中则返回Cancel：

Dynamic creation of a dialog box. You can customize to your taste.

动态创建对话框。您可以根据自己的口味进行定制。

Note there is no external dependency here except winform

注意这里除了 winform 没有外部依赖

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;
    }

usage

用法

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

Without adding a reference to Microsoft.VisualBasic:

不添加对 Microsoft.VisualBasic 的引用：

// "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");

See these for further information:
ScriptControl
MsgBox in JScript
