windows 10 (现代)通用应用平台(UWP)消息框

Question

如何在Windows10(现代)通用应用程序平台(UWP)上制作messagebox，就像在windows clasic form(messagebox.show)上一样？谢谢

Answer 1

对于通用应用程序，新的API要求您使用await

MessageDialog().ShowAsync() (in Windows.UI.Popups) 
// to bring it into line with Win 8.1.

var dialog = new MessageDialog("Your message here Hello");
await dialog.ShowAsync();

Answer 2

您可以这样做：

var dialog = new MessageDialog("Your message here");
await dialog.ShowAsync();

Answer 3

var dialog = new MessageDialog("Hello World");
await dialog.ShowAsync();
