Implement Mahapps MessageBox with OK and Cancel
提问by mukul nagpal
I am trying to implement Mahapps Metro Message boxin my code, but want to use it on a class, not any WPF Window, can I achieve this ?, because I don't want to use ordinary Message Boxes.
我正在尝试Mahapps Metro Message box在我的代码中实现，但想在一个class而不是任何一个上使用它WPF Window，我能做到吗？，因为我不想使用普通的Message Boxes.
switch(x)
{
case "a":
//Do something
break;
case "b":
var result = MessageBox.Show("TitleMessage","If you want to continue",MessageboxButton.YesNo);
break;
}
so instead of this MessageBox, I want to use Mahapps Message Box, then use this result variable.
所以不是这个MessageBox，我想使用Mahapps Message Box，然后使用这个结果变量。

Since the ShowMessageAsync method is an extension method of the MetroWindow class, you need to have a window to be able to call it.
由于 ShowMessageAsync 方法是 MetroWindow 类的扩展方法，因此您需要有一个窗口才能调用它。
If your applications's main window is a metro window you should be able to call the method like this from any class that has a reference to the PresentationFramework assembly:
如果您的应用程序的主窗口是一个 Metro 窗口，您应该能够从任何引用 PresentationFramework 程序集的类中调用这样的方法：
var metroWindow = (Application.Current.MainWindow as MetroWindow);
await metroWindow.ShowMessageAsync("title", "message...");
