MessageBox按钮？

Question

如果消息框上的yes按钮被按下了，我该如何说呢？在C#中。

Answer 1

如果你确实想要Yes和No按钮(假设是WinForms)：

void button_Click(object sender, EventArgs e)
{
    var message = "Yes or No?";
    var title = "Hey!";
    var result = MessageBox.Show(
        message,                  // the message to show
        title,                    // the title for the dialog box
        MessageBoxButtons.YesNo,  // show two buttons: Yes and No
        MessageBoxIcon.Question); // show a question mark icon

    // the following can be handled as if/else statements as well
    switch (result)
    {
    case DialogResult.Yes:   // Yes button pressed
        MessageBox.Show("You pressed Yes!");
        break;
    case DialogResult.No:    // No button pressed
        MessageBox.Show("You pressed No!");
        break;
    default:                 // Neither Yes nor No pressed (just in case)
        MessageBox.Show("What did you press?");
        break;
    }
}

Answer 2

if(DialogResult.OK==MessageBox.Show("Do you Agree with me???"))
{
         //do stuff if yess
}
else
{
         //do stuff if No
}

Answer 3

.NET 4.5的正确答案的更新版本为。

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxImage.Question) 
    == MessageBoxResult.Yes)  
{
// If yes
}
else  
{
// If no
}

此外，如果您希望将按钮绑定到视图模型中的命令，则可以使用以下方法。这与MvvmLite兼容：

public RelayCommand ShowPopUpCommand
{
   get
   {
   return _showPopUpCommand ??
      (_showPopUpCommand = new RelayCommand(
         () =>
               {
                // Put if statement here
               }
      }));
   }
}
