C# TCP

#1、TCP 服务器
1.创建TCP服务器

            //绑定IP地址
            s_c.Bind(new IPEndPoint(IPAddress.Any, Convert.ToInt32(this.textBox1.Text)));
            // 允许10个连接
            s_c.Listen(10);

            Thread acc = new Thread(Accept);
            acc.IsBackground = true;
            acc.Start();

2.等待客户端连接

        public void Accept()
        {
            //等待一个连接
            Socket click = s_c.Accept();

            //打印客户端IP地址 端口号
            IPEndPoint port = click.RemoteEndPoint as IPEndPoint;
            this.label3.Text = port.Address.ToString();
            this.label5.Text = port.Port.ToString();

            //接收数据线程
            Thread js_data = new Thread(get_data);
            js_data.IsBackground = true;
            js_data.Start(click);

          //发送数据线程
            Thread fs_data = new Thread(send);
            fs_data.IsBackground = true;
            fs_data.Start(click);

            Accept();
        }

3.发送数据

        //发送数据
        public void send(Object socket_click)
        {
            Socket fs_data = (Socket)socket_click;
            while (true)
            {
                if (fs == true)
                {
                    //发送数据
                    fs_data.Send(Encoding.UTF8.GetBytes(this.richTextBox2.Text));
                    fs = false;
                }
                if(fs_imag==true)
                {
                    byte[] buttfer = ReadImageFile(@"C:\Users\Administrator\Desktop\5.jpg");
                    fs_data.Send(buttfer);
                    fs_imag = false;
                }
            }
            //send(fs_data);
        }

2、TCP客户端

	1.连接服务器

            Socket s_s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            this.label3.Text = this.textBox2.Text;
            s_s.Connect(this.textBox1.Text, Convert.ToInt32(this.textBox2.Text));
            MessageBox.Show("连接" + this.textBox1.Text + ":" + this.textBox2.Text + "成功,可以发送数据了");
            this.label3.Text = "连接成功";

            //s_s.Send(Encoding.UTF8.GetBytes(this.richTextBox1.Text));
            //MessageBox.Show("发送成功");

            //发送数据线程
            Thread fs_data = new Thread(fx_data);
            fs_data.Start(s_s);

2.发送数据

        public void fx_data(Object socket)
        {
            Socket s_s = (Socket)socket;
            while (true)
            {
                if (zhi == "open")
                {
                    s_s.Send(Encoding.UTF8.GetBytes(this.richTextBox1.Text));
                    MessageBox.Show("发送成功");
                    zhi = "quit";
                }
                if (zhi == "close")
                {
                    break;
                }
            }
            //fx_data(s_s);
        }
