如何从XAML获取屏幕大小？ [英] How to obtain screen size from xaml?

问题描述

我在C＃上使用wpf设计GUI，我想从xaml代码获取屏幕大小（宽度和高度的值）。

I'm using wpf on C# to design GUI, and I want to get screen size (The value of Width and Height) from xaml code.

如何从C＃代码中获取它们

I knew how to get them from C# code as

   Width = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
   Height = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;

但我不知道如何从 XAML 代码。

But I don't know how to get them from XAML code.
