Answer 1

最简单的办法..
Control.CheckForIllegalCrossThreadCalls=false;
或者使用代理

Answer 2

Control.CheckForIllegalCrossThreadCalls=false;帮助中如是说：该值指示是否捕获对错误线程的调用

Answer 3

Form1://假设窗体class 名字为Form1 
增加
delegate void SetTextCallback(string text);public void SetData(string data)
        {
            SetText(data);
        }
        private void SetText(string text)
        {
            // InvokeRequired required compares the thread ID of the
            // calling thread to the thread ID of the creating thread.
            // If these threads are different, it returns true.
            if (this.textBox1.InvokeRequired)
            {
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.textBox1.Text = text;
            }
        }
 修改：
//Thread clientService = new Thread(new ThreadStart(p.ProcessClient));
Thread clientService = new Thread(p.ProcessClient);                clientService.IsBackground = true;
//clientService.Start();
  clientService.Start(this);
// public void ProcessClient()
public void ProcessClient(object o)            {
                Form1 f = (Form1)o;
                _byteReceive = new byte[140];
                NetworkStream ns = new NetworkStream(_currentSocket);                int nReceiveCount = ns.Read(_byteReceive, 0, _byteReceive.Length);
                _strReceive = Encoding.ASCII.GetString(_byteReceive, 0, nReceiveCount);//收到的内容               // Console.WriteLine(_strReceive);
              f.SetData(_strReceive);
            }

Answer 4

Form1 f = (Form1)o;
不用new？

Answer 5

不用new
new 就返回不到创建线程的窗体了。
