C# 线程中操作空间

1.在Form1类中添加以下代码

 private delegate void UpdateStatusDelegate(string status);

        private void UpdateStatus(string status)

        {

            this.textBox1.Text = status;

        }

2.

 private void OnBtUsbRead(object sender, EventArgs e)

        {

            Thread t = new Thread(new ThreadStart(Go));

            t.Start();   // Run Go() on the new thread.

            Go();        // Simultaneously run Go() in the main thread.

         }

        private  void Go()

        {

            this.BeginInvoke(new UpdateStatusDelegate(UpdateStatus), new object[] { "123"});

        }
