它完美无缺，但并不完全是我正在寻找的...我需要一个代码告诉我目前哪个是FOREGROUND窗口...所以使用这个其他代码我存档了...

说明：第一个代码为我提供了当时正在运行的所有应用程序的进程名称......第二个代码为我提供了“WINDOW NAME”和前景中应用程序的代码.... ......我需要的......是FOREGROUND WINDOWS的过程名称...所以你可以看到......如果我可以“混合”他们两个......它会给我我需要的东西。 .. ps ...我只需要一个变量中的ACTUAL前景窗口的名称，所以我可以在代码里面使用....不需要windows，box o桌面上的实际文本...谢谢
答案 0 :(得分：2)
要获取前景窗口的进程名称，您必须获取foregound Window GetForegroundWindow，然后使用GetWindowThreadProcessId获取其进程ID：
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
public static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll", SetLastError = true)]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);
Process GetActiveProcess()
{
IntPtr hwnd = GetForegroundWindow();
uint pid;
GetWindowThreadProcessId(hwnd, out pid);
Process p = Process.GetProcessById((int)pid);
return p;
}
然后您可以获取进程名称：
GetActiveProcess().ProcessName
