C# 带有“是”和“否”按钮的消息框

我正在使用Windows Phone 8，我有一个场景，在该场景中，我正在询问用户，因此用户必须单击是或否

但是meassage框只有OK和Cancel按钮，我不需要它

这是我的密码：

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);
            }

如何将其修改为“是”和“否”按钮？我还可以有3个按钮以及自定义文本按钮吗

否，MessageBox是一种密封类型

您需要创建自己的MessageBox控件，该控件具有“是”和“否”按钮。

API仅公开确定/取消。您可以使用来自的Coding4Fun消息提示符创建是/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();

API仅公开“确定”和“取消”。如果您需要使用不同的按钮，恐怕您必须使用自定义消息框

例如

另一个选项是使用XNA框架中的Guide类。有一个BeginShowMessageBox方法，允许您选择为按钮传入任何字符串

您可以使用此自定义消息框

你可以调用这个消息框

是否按钮

SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes or No Message Box...!", SLMessageBox.MessageBoxButtons.YesNo, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();

仅适用于“确定”按钮

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

用于“确定”和“取消”按钮

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

编辑： 并检查用户单击的MessageBox的结果

SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes, No and Cancel Buttons Message Box...!", SLMessageBox.MessageBoxButtons.YesNoCancel, , SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
messBox.OnMessageBoxClosed += messBox_OnDeleteMessageBoxClosed;

private void messBox_OnDeleteMessageBoxClosed(MessageBoxResult result)
{
   if(result==MessageBoxResult.Yes)
   {
     //....
   }
   else if(result==MessageBoxResult.No)
   {
     //....
   }
   else
   {
     //...
   }
}

好的，你能告诉我如何创建我自己的消息框吗？是的，我会尝试并让你知道。我需要在MessagePrompt中使用哪个程序集？这里有一个勾号按钮以及“是”和“否”按钮，如何删除勾号按钮？我会尝试这个，我还可以有三个按钮吗？是的，它在YesNoCancel按钮中。公共枚举MessageBoxButtons{Ok，YesNon，YesNoCancel，OkCancel}好的，那么它将是SLMessageBox.MessageBoxButtons.YesNoCancel对吗？我还可以修改名称Yes，No和cancel，喜欢自定义名称吗？@Goofy我已经编辑了我的答案。是的，你可以修改按钮名称。

SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes, No and Cancel Buttons Message Box...!", SLMessageBox.MessageBoxButtons.YesNoCancel, , SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
messBox.OnMessageBoxClosed += messBox_OnDeleteMessageBoxClosed;

private void messBox_OnDeleteMessageBoxClosed(MessageBoxResult result)
{
   if(result==MessageBoxResult.Yes)
   {
     //....
   }
   else if(result==MessageBoxResult.No)
   {
     //....
   }
   else
   {
     //...
   }
}

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
            }
