没有这样的事情: 我建议你自己写，并且在你需要的时候使用它。

你是说 InputBox? 只要查看 Microsoft.VisualBasic 名称空间。

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。

根本没有。如果你真的想在 C # 中使用 VB InputBox，你可以。只要添加对微软的参考。VisualBasic.dll，您可以在那里找到它。

但是我建议 没有使用它。它是丑陋的和过时的 IMO。

最佳答案

添加对 Microsoft.VisualBasic的引用，InputBox在 Microsoft.VisualBasic.Interaction名称空间中:

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

只有 prompt的第一个参数是强制的

添加对 Microsoft.VisualBasic的引用并使用以下函数:

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

最后2个数字是 X/Y 位置，用于显示输入对话框。

总结一下:

  • 有 C # 没有。

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

    1. 在 解决方案资源管理器中右键单击 参考文献文件夹。
    2. 选择 添加参考文献..。
    3. 在 .NET选项卡中(在较新的 VisualStudio 版本 -集合选项卡中) ，选择 微软，VisualBasic
    4. 点击 好的

然后您可以使用前面提到的代码:

string input = Microsoft.VisualBasic.Interaction.InputBox("Prompt", "Title", "Default", 0, 0);
  • 编写您自己的 InputBox。
  • 使用 别人的。

也就是说，我建议您首先考虑输入框的需要。对话并不总是做事的最佳方式，有时它们弊大于利——但这取决于具体情况。

您不仅应该添加 Microsoft。VisualBasic 到您的项目参考列表中，但是您也应该声明“使用 Microsoft。所以你只需要使用“交互”。用 Inputbox (“ ...”)’代替微软。VisualBasic.互动。输入框

返回用户输入的字符串; 如果命中 Cancel，返回空字符串:

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

返回 String作为 裁判参数，如果它们命中 OK返回 true，如果它们命中 Cancel返回 false:

    public static Boolean InputQuery(String caption, String prompt, ref String value)
{
Form form;
form = new Form();
form.AutoScaleMode = AutoScaleMode.Font;
form.Font = SystemFonts.IconTitleFont;


SizeF dialogUnits;
dialogUnits = form.AutoScaleDimensions;


form.FormBorderStyle = FormBorderStyle.FixedDialog;
form.MinimizeBox = false;
form.MaximizeBox = false;
form.Text = caption;


form.ClientSize = new Size(
Toolkit.MulDiv(180, dialogUnits.Width, 4),
Toolkit.MulDiv(63, dialogUnits.Height, 8));


form.StartPosition = FormStartPosition.CenterScreen;


System.Windows.Forms.Label lblPrompt;
lblPrompt = new System.Windows.Forms.Label();
lblPrompt.Parent = form;
lblPrompt.AutoSize = true;
lblPrompt.Left = Toolkit.MulDiv(8, dialogUnits.Width, 4);
lblPrompt.Top = Toolkit.MulDiv(8, dialogUnits.Height, 8);
lblPrompt.Text = prompt;


System.Windows.Forms.TextBox edInput;
edInput = new System.Windows.Forms.TextBox();
edInput.Parent = form;
edInput.Left = lblPrompt.Left;
edInput.Top = Toolkit.MulDiv(19, dialogUnits.Height, 8);
edInput.Width = Toolkit.MulDiv(164, dialogUnits.Width, 4);
edInput.Text = value;
edInput.SelectAll();




int buttonTop = Toolkit.MulDiv(41, dialogUnits.Height, 8);
//Command buttons should be 50x14 dlus
Size buttonSize = Toolkit.ScaleSize(new Size(50, 14), dialogUnits.Width / 4, dialogUnits.Height / 8);


System.Windows.Forms.Button bbOk = new System.Windows.Forms.Button();
bbOk.Parent = form;
bbOk.Text = "OK";
bbOk.DialogResult = DialogResult.OK;
form.AcceptButton = bbOk;
bbOk.Location = new Point(Toolkit.MulDiv(38, dialogUnits.Width, 4), buttonTop);
bbOk.Size = buttonSize;


System.Windows.Forms.Button bbCancel = new System.Windows.Forms.Button();
bbCancel.Parent = form;
bbCancel.Text = "Cancel";
bbCancel.DialogResult = DialogResult.Cancel;
form.CancelButton = bbCancel;
bbCancel.Location = new Point(Toolkit.MulDiv(92, dialogUnits.Width, 4), buttonTop);
bbCancel.Size = buttonSize;


if (form.ShowDialog() == DialogResult.OK)
{
value = edInput.Text;
return true;
}
else
{
return false;
}
}


/// <summary>
/// Multiplies two 32-bit values and then divides the 64-bit result by a
/// third 32-bit value. The final result is rounded to the nearest integer.
/// </summary>
public static int MulDiv(int nNumber, int nNumerator, int nDenominator)
{
return (int)Math.Round((float)nNumber * nNumerator / nDenominator);
}

注意 : 任何代码都会发布到公共领域，不需要任何属性。

动态创建对话框。您可以根据自己的喜好进行自定义。

注意，除了 winform 之外，这里没有外部依赖项

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;
}

用途

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

没有添加对 Microsoft 的引用。 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");

有关更多信息，请参见以下内容:
ScriptControl
JScript 中的 MsgBox
JScript < br/> 中的输入和 MsgBox

.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);

我可以通过编写自己的代码来实现这一点。我不喜欢扩展到并依赖于大型图书馆的基本内容。

形式及设计师:

public partial class InputBox
: Form
{


public String Input
{
get { return textInput.Text; }
}


public InputBox()
{
InitializeComponent();
}


private void button2_Click(object sender, EventArgs e)
{
DialogResult = System.Windows.Forms.DialogResult.OK;
}


private void button1_Click(object sender, EventArgs e)
{
DialogResult = System.Windows.Forms.DialogResult.Cancel;
}


private void InputBox_Load(object sender, EventArgs e)
{
this.ActiveControl = textInput;
}


public static DialogResult Show(String title, String message, String inputTitle, out String inputValue)
{
InputBox inputBox = null;
DialogResult results = DialogResult.None;


using (inputBox = new InputBox() { Text = title })
{
inputBox.labelMessage.Text = message;
inputBox.splitContainer2.SplitterDistance = inputBox.labelMessage.Width;
inputBox.labelInput.Text = inputTitle;
inputBox.splitContainer1.SplitterDistance = inputBox.labelInput.Width;
inputBox.Size = new Size(
inputBox.Width,
8 + inputBox.labelMessage.Height + inputBox.splitContainer2.SplitterWidth + inputBox.splitContainer1.Height + 8 + inputBox.button2.Height + 12 + (50));
results = inputBox.ShowDialog();
inputValue = inputBox.Input;
}


return results;
}


void labelInput_TextChanged(object sender, System.EventArgs e)
{
}


}
