推荐答案

Hi

不幸的是，如果您的应用程序是Windows窗体或控制台应用程序，则在窗体/控件处于活动状态时，如果需要获取系统范围的键或仅按下这些键，则无需编写.

对于最后一种情况是检查事件Form.KeyDown.帮助中也有一个很好的例子.

Hi

unfortunately you don't write if your application is a Windows Form or a console application, if you need to get the keys system wide or only those keys pressed, while the form / control is active.

For the last situation check the event Form.KeyDown. There is a good example in the help as well.
