\#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);
            }
