C# 线程 - STAThreadAttribute 异常

Question

我会尽力解释。 基本上我在无形系统托盘应用程序中使用全局热键。 为此，我正在使用此热键管理器：Global hotkey in console application 调用热键时，我开始收到此异常：

当前线程必须设置为单线程单元 (STA) 模式 在可以进行 OLE 调用之前。确保您的 Main 函数具有 STAThreadAttribute 标记就可以了。

我“修复”异常的方式是：https://stackoverflow.com/a/6373700/6329242 我的全局热键开始工作，除了一个，我得到了同样的例外。实在找不到解决办法。

我是这样称呼他们的：

      static void HotKeyManager_HotKeyPressed(object sender, HotKeyEventArgs e)
    {
        switch (e.Key)
        {
            case Keys.D1:
                CaptureAreaOfScreenForm caos2 = new CaptureAreaOfScreenForm();
                var thread1 = new Thread(new ParameterizedThreadStart(param => { caos2.Show(); }));
                thread1.SetApartmentState(ApartmentState.STA);
                thread1.Start();
                break;
            case Keys.D2:
                CaptureWorkingArea cwa2 = new CaptureWorkingArea();
                var thread2 = new Thread(new ParameterizedThreadStart(param => { cwa2.CaptureTheWorkingArea(); }));
                thread2.SetApartmentState(ApartmentState.STA);
                thread2.Start();
                break;
            case Keys.D3:
                CaptureFullScreen cfs2 = new CaptureFullScreen();
                var thread3 = new Thread(new ParameterizedThreadStart(param => { cfs2.CaptureDesktop(); }));
                thread3.SetApartmentState(ApartmentState.STA);
                thread3.Start();
                break;
            case Keys.D4:
                CaptureAllScreens cas2 = new CaptureAllScreens();
                var thread4 = new Thread(new ParameterizedThreadStart(param => { cas2.CaptureScreens(); }));
                thread4.SetApartmentState(ApartmentState.STA);
                thread4.Start();
                break;
            case Keys.D5:
                UploadFromFile uff2 = new UploadFromFile();
                var thread5 = new Thread(new ParameterizedThreadStart(param => { uff2.UploadFile(); }));
                thread5.SetApartmentState(ApartmentState.STA);
                thread5.Start();
                break;
        }
        //collect the garbage
        GC.Collect();
    }

（问题是 Keys.D1）。有问题的和其他的区别是我调用了一个表单类。 （其他人工作正常）

附：如果我可以添加一些有助于解决它的东西或者更多的东西告诉我这样做，我就是编程新手。谢谢。

注意。这是相当狡猾的——Windows 窗体旨在通过单个线程运行所有窗体和控件，但这并不意味着你不会让它工作。您确实需要确保在它们运行的​​同一线程中创建事物，因此请尝试更改它以便您也在线程内创建表单...
