如何在 C# ion WP7 中显示来自 static 方法的 MessageBox？

Question

I have a Page on Windows Phone that is called asynchronously, from which I want to show a MessageBox. I would normally:

this.Dispatcher.BeginInvoke(() => MessageBox.Show("The message"));

but this doesn't quite work in a static method.

How do I get the MessageBox to display from a static method?

You can access the UI dispatcher using Application.Current.RootVisual.Dispatcher :

Dispatcher dispatcher = Application.Current.RootVisual.Dispatcher;
dispatcher.BeginInvoke(() => MessageBox.Show("The message"));
