C#匿名代理的使用

 private delegate void CrossThreadOperationControl();           // 將代理執行個體化為一個匿名代理             CrossThreadOperationControl CrossDelete = delegate()            {                MessageBoxButtons buttons = MessageBoxButtons.OKCancel;                DialogResult dr = MessageBox.Show("Master，please to have a rest！", "Interrupt", buttons);                if (dr == DialogResult.OK)                {                    BlockInput(true);                    SendMessage(this.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2);                    myTimere.Stop();                    System.Threading.Thread.Sleep(mySpantime);                    myTimere.Start();                    BlockInput(false);                }                else                {                    myWatch.Stop();                    MessageBox.Show("Time setting be cancled！");                    Application.Exit();                }            };            this.Invoke(CrossDelete);方法2        this.Invoke(new MethodInvoker(delegate()                {                MessageBoxButtons buttons = MessageBoxButtons.OKCancel;                DialogResult dr = MessageBox.Show("Master，please to have a rest！", "Interrupt", buttons);                if (dr == DialogResult.OK)                {                    BlockInput(true);                    SendMessage(this.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2);                    myTimere.Stop();                    System.Threading.Thread.Sleep(mySpantime);                    myTimere.Start();                    BlockInput(false);                }                else                {                    myWatch.Stop();                    MessageBox.Show("Time setting be cancled！");                    Application.Exit();                }                }));
