切换/创建桌面C#内部打开表单

您好，我已经在这个程序上工作了很长一段时间，我的目标是有一个锁定系统，可以在桌面之间切换，在第二个屏幕上有一个登录表单，允许您登录，但我遇到了一个问题，我无法从2太近的登录，所以第二个桌面可以被破坏，我必须手动关闭它我已经尝试过了调用close和hide时，我试图破坏进程，但我不会关闭，但它不会关闭。 如果我使用.ShowDialog方法打开表单，但如果我使用.show方法打开表单。它将关闭表单，但工作的任何部分都将显示为空白窗口

form1这是处理请求的主要表单

        public Form1()
        {
            InitializeComponent();
            // Create the thread object. This does not start the thread.
            Worker workerObject = new Worker();
            Thread workerThread = new Thread(workerObject.DoWork);

            workerThread.Start();
            System.Threading.Thread.Sleep(3000);
            workerObject.RequestStop();

        }

    }


    public partial class Worker
    {
            static Desctop mDesktop = new Desctop();

        // This method will be called when the thread is started. 
        public  void DoWork()
        {

            mDesktop.CreateNewDesktop("Mayshotspot");
            using (Form2 frm = new Form2())
            {

                frm.ShowDialog();
                while (!_shouldStop) { }
                frm.Close(); // this will not close the form 
            }

            mDesktop.DestroyDesktop();
            mDesktop.destroyProces();




        }

        public void RequestStop()
        {
            _shouldStop = true;
        }
        // Volatile is used as hint to the compiler that this data 
        // member will be accessed by multiple threads. 
        private volatile bool _shouldStop;



    }




}

表单2-出现在桌面开关上的登录屏幕目前处于默认状态，直到我找到它不关闭的原因为止

请查看可能的解决方案。您好，我已将其分解，我可以让它启动，但不能将其放在第二个桌面上，或者我将获得框架，但它不会自行关闭更多：-（例如）使用 S删除所有<代码>，删除<代码>命名空间< /代码>，删除空白行，是否真的“<代码> ExtNe>代码>声明？等等。您的读者必须水平滚动和垂直滚动，这通常会使这个问题变得很不吸引人。对不起，我希望这对你来说是一个更好的阅读。我已经删除了所有的基本功能，并删除了一些函数
