推荐答案

在Windows API有一个名为函数GetForegroundWindow().您将需要使用P / Invoke来调用到的Win32 API。在P / Invoke的wiki有更多信息中的C＃用户。

The Windows API has a function called GetForegroundWindow(). You will need to use P/Invoke to call into the Win32 API. The P/Invoke wiki has more info for C# users.

请参阅this页它获取当前应用程序的标题（名称）的一个例子。
