从对话框

试试这个。它被设计成与MessageBox相对应的。不过，它并没有改变基于操作系统的样式。它看起来像Vista的。

下面是一个例子，它是从原来的home（一个Paint.NET插件）开始的。它将展开以适应提示。

InputBox.cs：

internal partial class InputBoxForm : Form 
    { 
     Size lbltextoriginalsize; 
     Size pnlwhiteoroginalsize; 
     public InputBoxForm(string text, string defaultvalue, string caption) 
     { 
      InitializeComponent(); 
      this.pnlWhite.Resize += new System.EventHandler(this.pnlWhite_Resize); 
      this.lblText.Resize += new System.EventHandler(this.lblText_Resize); 
      picIcon.Image = SystemIcons.Question.ToBitmap(); 
      lbltextoriginalsize = lblText.Size; 
      pnlwhiteoroginalsize = pnlWhite.Size; 
      this.lblText.Text = text; 
      this.txtOut.Text = defaultvalue; 
      this.Text = caption; 
     } 

     private void lblText_Resize(object sender, EventArgs e) 
     { 
      pnlWhite.Size += lblText.Size - lbltextoriginalsize; 
     } 

     private void pnlWhite_Resize(object sender, EventArgs e) 
     { 
      this.Size += pnlWhite.Size - pnlwhiteoroginalsize; 
     } 

     public string Value 
     { 
      get { return txtOut.Text; } 
     } 
    } 

    /// 
    /// A counterpart to the MessageBox class, designed to look similar (at least on Vista) 
    /// 
    public static class InputBox 
    { 
     public static DialogResult Show(string text, out string result) 
     { 
      return ShowCore(null, text, null, null, out result); 
     } 
     public static DialogResult Show(IWin32Window owner, string text, out string result) 
     { 
      return ShowCore(owner, text, null, null, out result); 
     } 
     public static DialogResult Show(string text, string defaultValue, out string result) 
     { 
      return ShowCore(null, text, defaultValue, null, out result); 
     } 
     public static DialogResult Show(IWin32Window owner, string text, string defaultValue, out string result) 
     { 
      return ShowCore(owner, text, defaultValue, null, out result); 
     } 
     public static DialogResult Show(string text, string defaultValue, string caption, out string result) 
     { 
      return ShowCore(null, text, defaultValue, caption, out result); 
     } 
     public static DialogResult Show(IWin32Window owner, string text, string defaultValue, string caption, out string result) 
     { 
      return ShowCore(owner, text, defaultValue, caption, out result); 
     } 

     private static DialogResult ShowCore(IWin32Window owner, string text, string defaultValue, string caption, out string result) 
     { 
      InputBoxForm box = new InputBoxForm(text, defaultValue, caption); 
      DialogResult retval = box.ShowDialog(owner); 
      result = box.Value; 
      return retval; 
     } 
    }

返回值我平时做这样的事情：

public class MyInputDialog : Form { 
    public static string Execute(string Prompt) { 
     using (var f = new MyInputDialog()) { 
     f.lblPrompt.Text = Prompt; 
     f.ShowModal(); 
     return f.txtInput.Text; 
     } 
    } 
}

离开了所有的错误处理，如果用户取消什么，等。

我建议你Interaction.InputBox（Microsoft.VisualBasic参考需要）：

inputValue = Interaction.InputBox("Text for the prompt", "Title of the dialog", "");

当用户按下取消时，inputValue将为""。

这是我会怎么调用对话框

var regStoreForm = new RegisterStoreForm(storeID,password); 
      if (regStoreForm.ShowDialog(this) == DialogResult.OK) 
      { 
       storeID = regStoreForm.StoreId; 
       password = regStoreForm.StorePassword; 
      }; 
      regStoreForm.Dispose();

这是对话框的样子

public partial class RegisterStoreForm : Form 
    { 
     public int StoreId { get; set; } 
     public String StorePassword { get; set; } 

     public RegisterStoreForm(int storeId,string password) 
     { 
      InitializeComponent(); 
      StoreId = storeId; 
      StorePassword = password; 
      this.textBoxPassword.Text = StorePassword; 
      this.textBoxStoreId.Text = StoreId.ToString(); 
     } 

     private void OKbutton_Click(object sender, EventArgs e) 
     { 
      StoreId = Convert.ToInt16(textBoxStoreId.Text); 
      StorePassword = textBoxPassword.Text; 
      this.DialogResult = DialogResult.OK; 
      this.Close(); 
     } 
    }
