C# 网络编程小问题

private void Proccess()
        {
            if (acceptedSocket.Connected)
            {
                while (flag)
                {
                    byte[] receiveByte = new byte[64];
                    acceptedSocket.Receive(receiveByte, receiveByte.Length, 0);
                    string strInfo = Encoding.BigEndianUnicode.GetString(receiveByte);
                    this.Invoke(new SetTextCallback(SetText), new object[] { strInfo });

                }
            }
      }
中
acceptedSocket.Receive(receiveByte, receiveByte.Length, 0);
和
this.Invoke(new SetTextCallback(SetText), new object[] { strInfo });不清楚是什么意思
能不能讲讲啊
