如何在MessageBox.Show对话框中更改“是”和“否”按钮的按钮文本？

24

只需添加一个新的形式，并添加按钮和标签。在其构造函数中给出要显示的值和按钮的文本等，并从项目中的任何位置调用它。

In project -> Add Component -> Windows Form and select a form

添加一些标签和按钮。

初始化构造函数中的值并从任何地方调用它。

public class form1:System.Windows.Forms.Form 
{ 
    public form1() 
    { 
    } 

    public form1(string message,string buttonText1,string buttonText2) 
    { 
     lblMessage.Text = message; 
     button1.Text = buttonText1; 
     button2.Text = buttonText2; 
    } 
} 

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project. 

// Calling 

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2"); 
frm.ShowDialog();

您还需要为添加的按钮设置对话框结果属性。更多细节在这里：http://www.switchonthecode.com/tutorials/csharp-dialogs-part-2-custom-dialogs – CEPA 2012-09-20 00:28:56

是的，然后你用DialogResult检查ShowDialog（）。 – kbvishnu 2012-09-20 06:35:18

这是一种实用的方法吗？ – 2015-09-19 16:30:54

我不认为这会很简单！转到此链接： https://www.codeproject.com/Articles/18399/Localizing-System-MessageBox

下载此源码。采取MessageBoxManager.cs文件，将其添加到您的项目。现在只要在你的代码（例如在您的Program.cs文件中的Main（）方法）注册了一次，它的工作每次调用MessageBox.Show（时间）：

MessageBoxManager.OK = "Alright"; 
    MessageBoxManager.Yes = "Yep!"; 
    MessageBoxManager.No = "Nope"; 
    MessageBoxManager.Register();

为源见this answer代码为MessageBoxManager.cs。

这可能不是最漂亮的，但如果你不想使用MessageBoxManager，（这是真棒）：

public static DialogResult DialogBox(string title, string promptText, ref string value, string button1 = "OK", string button2 = "Cancel", string button3 = null) 
    { 
     Form form = new Form(); 
     Label label = new Label(); 
     TextBox textBox = new TextBox(); 
     Button button_1 = new Button(); 
     Button button_2 = new Button(); 
     Button button_3 = new Button(); 

     int buttonStartPos = 228; //Standard two button position 


     if (button3 != null) 
      buttonStartPos = 228 - 81; 
     else 
     { 
      button_3.Visible = false; 
      button_3.Enabled = false; 
     } 


     form.Text = title; 

     // Label 
     label.Text = promptText; 
     label.SetBounds(9, 20, 372, 13); 
     label.Font = new Font("Microsoft Tai Le", 10, FontStyle.Regular); 

     // TextBox 
     if (value == null) 
     { 
     } 
     else 
     { 
      textBox.Text = value; 
      textBox.SetBounds(12, 36, 372, 20); 
      textBox.Anchor = textBox.Anchor | AnchorStyles.Right; 
     } 

     button_1.Text = button1; 
     button_2.Text = button2; 
     button_3.Text = button3 ?? string.Empty; 
     button_1.DialogResult = DialogResult.OK; 
     button_2.DialogResult = DialogResult.Cancel; 
     button_3.DialogResult = DialogResult.Yes; 


     button_1.SetBounds(buttonStartPos, 72, 75, 23); 
     button_2.SetBounds(buttonStartPos + 81, 72, 75, 23); 
     button_3.SetBounds(buttonStartPos + (2 * 81), 72, 75, 23); 

     label.AutoSize = true; 
     button_1.Anchor = AnchorStyles.Bottom | AnchorStyles.Right; 
     button_2.Anchor = AnchorStyles.Bottom | AnchorStyles.Right; 
     button_3.Anchor = AnchorStyles.Bottom | AnchorStyles.Right; 

     form.ClientSize = new Size(396, 107); 
     form.Controls.AddRange(new Control[] { label, button_1, button_2 }); 
     if (button3 != null) 
      form.Controls.Add(button_3); 
     if (value != null) 
      form.Controls.Add(textBox); 

     form.ClientSize = new Size(Math.Max(300, label.Right + 10), form.ClientSize.Height); 
     form.FormBorderStyle = FormBorderStyle.FixedDialog; 
     form.StartPosition = FormStartPosition.CenterScreen; 
     form.MinimizeBox = false; 
     form.MaximizeBox = false; 
     form.AcceptButton = button_1; 
     form.CancelButton = button_2; 

     DialogResult dialogResult = form.ShowDialog(); 
     value = textBox.Text; 
     return dialogResult; 
    }
