我在 Windows Phone 8 上工作，我在消息框中询问用户，因此用户必须单击“是”或“否”。
But the meassage box is having only OK and Cancel buttons, which i dont need it.
但是消息框只有确定和取消按钮，我不需要它。
Here is my code:
这是我的代码：
MessageBoxResult m = MessageBox.Show("Are you sure? This will delete all your data", "Attention!", MessageBoxButton.OKCancel);
if (m == MessageBoxResult.Cancel)
{
}
else
{
MessageBox.Show("Data Deleted", "Done", MessageBoxButton.OK);

SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok and Cancel Message Box...!", SLMessageBox.MessageBoxButtons.OkCancel, SLMessageBox.MessageBoxIcon.Information);

private void messBox_OnDeleteMessageBoxClosed(MessageBoxResult result)
{
if(result==MessageBoxResult.Yes)
{
//....
}

{
//....

The API only exposes the OK/Cancel. you can use the Coding4Fun MessagePrompt from Coding4FunToolkitto create Yes/No message:
API 只公开确定/取消。您可以使用Coding4Fun MessagePrompt从Coding4FunToolkit创建是/否消息：
MessagePrompt msgPrompt = new MessagePrompt();
msgPrompt.Message = "Your Message.";
Button yesBtn = new Button() { Content = "Yes" };
yesBtn.Click += new RoutedEventHandler(yesBtn_Click);
Button noBtn = new Button() { Content = "No" };
noBtn.Click += new RoutedEventHandler(noBtn_Click);
msgPrompt.ActionPopUpButtons.Add(noBtn);
msgPrompt.ActionPopUpButtons.Add(yesBtn);
msgPrompt.Show();

The API only exposes "OK" and "Cancel". If you need to use different button I'm afraid you'll have to use a custom message box.
API 只公开“OK”和“Cancel”。如果您需要使用不同的按钮，恐怕您将不得不使用自定义消息框。

Another option is to use the Guide class from the XNA framework. There is a BeginShowMessageBox method giving you the option to pass in whatever strings you wish for the buttons.
另一种选择是使用 XNA 框架中的 Guide 类。有一个 BeginShowMessageBox 方法，您可以选择为按钮传递任何字符串。

No, MessageBox is a sealed type.
不，MessageBox 是密封类型。
You will need to make your own MessageBox control, that has "Yes" and "No" buttons.
您需要制作自己的 MessageBox 控件，该控件具有“是”和“否”按钮。

if (MessageBox.Show("Are you sure?", "Attention!!", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
{
//this block will be executed when Yes is selected
MessageBox.Show("Data Deleted", "Done", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
}
else
{
//this block will be executed when No is selected
}
