如何检测修饰键状态在WPF?状态、WPF

有没有办法,我可以使用,每当我需要访问控制,Shift键,Alt键按钮是否造成了一些全球性的结构?例如在的MouseDown 的事件的TreeView

Is there some global constructs that I can use whenever I need to access whether the Control, Shift, Alt buttons are down? For instance inside MouseDown event of a TreeView.

如果这样怎么办?

推荐答案

使用类Keyboard.使用Keyboard.IsKeyDown您可以检查是否控制,Shift键,Alt键是失望吧。

Use class Keyboard. Using Keyboard.IsKeyDown you can check if Control, Shift, Alt is down now.

有关转变:

if (Keyboard.IsKeyDown(Key.LeftShift) || Keyboard.IsKeyDown(Key.RightShift))
{ /* Your code */ }

有关控制:

if (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))
{ /* Your code */ }

有关ALT:

if (Keyboard.IsKeyDown(Key.LeftAlt) || Keyboard.IsKeyDown(Key.RightAlt))
{ /* Your code */ }
