使用 SetWindowsHookEx 检索全局按键的进程或线程 ID

Retrieve process- or thread-id of global keypress using SetWindowsHookEx

我有一个特定的应用程序,我可以使用

找到它
Process.GetProcesses()

并按 ProcessName 过滤。 我想过滤掉该进程的所有按键事件,不幸的是,只能将可选的线程 ID 作为最后一个参数传递给 SetWindowsHookEx

这就是为什么我考虑过滤传入的事件,但我无法找到一种方法来检索信息的来源。有什么解决办法吗?

回调信息在LowLevelKeyboardProc having another struct inside lparam: KBDLLHOOKSTRUCT

中提供
public partial class Form1 : Form 
{
    [DllImport("user32.dll")]
    static extern IntPtr GetForegroundWindow();

    [DllImport("user32.dll")]
    static extern uint GetWindowThreadProcessId(IntPtr hWnd, IntPtr ProcessId);

    Process process;

    public Form1() 
    {
        process = Process.GetProcesses()
            .Where(x => x.ProcessName == "MyProcessName")
            .FirstOrDefault();

        //init global keypress as needed
    }

    void gkh_KeyUp(object sender, KeyEventArgs e)
    {
        IntPtr handle = GetForegroundWindow();
        uint processID = GetWindowThreadProcessId(handle, IntPtr.Zero);
        if (p2.Threads.OfType<ProcessThread>().Any(x => x.Id == Convert.ToInt32(processID)))
        {
            //keypress in MyProcessName
        }
        e.Handled = true;
    }
