c# - 无法正确停止 HwndSource Hook

Question

如何正确停止钩子？由于挂钩，我无法正确关闭应用程序。

代码背后：

protected override void OnSourceInitialized(EventArgs e)
        {
            base.OnSourceInitialized(e);
            IntPtr windowHandle = (new WindowInteropHelper(this)).Handle;
            HwndSource src = HwndSource.FromHwnd(windowHandle);
            src.AddHook(new HwndSourceHook(WndProc));
        }

 private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
        {
            // Handle WM_DEVICECHANGE
            if (msg == 0x0219)
            {
RunService();
    }

我写了类似下面的东西，但它不会正确停止应用程序：

private void StopHook()
        {
            IntPtr windowHandle = (new WindowInteropHelper(this)).Handle;
            HwndSource src = HwndSource.FromHwnd(windowHandle);
            src.RemoveHook(new HwndSourceHook(this.WndProc));
        }

protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
        {
            base.OnClosing(e);
            StopService(); // to clear thread
            StopHook();
        }

更新：

我认为 RunService 导致了问题，但我正在使用 StopService 关闭所有线程。
