C# Socket通信实例

代码是抄来了，找不到出处了，经测试代码简洁可用

服务端代码：

using System;
using System.Text;
using System.Net.Sockets;
using System.Net;
using System.Threading;

namespace SocketServer
{
    internal class Program
    {
        private static readonly byte[] Result = new byte[1024];
        private const int MyProt = 8885; //端口 
        private static Socket _serverSocket;

        private static void Main()
        {
            //服务器IP地址
            var ip = IPAddress.Parse("127.0.0.1");
            _serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            _serverSocket.Bind(new IPEndPoint(ip, MyProt));  //绑定IP地址：端口
            _serverSocket.Listen(10);    //设定最多10个排队连接请求
            Console.WriteLine("启动监听{0}成功", _serverSocket.LocalEndPoint);
            //通过Clientsoket发送数据
            var myThread = new Thread(ListenClientConnect);
            myThread.Start();
            Console.ReadLine();
        }

        /// <summary>
        /// 监听客户端连接
        /// </summary>
        private static void ListenClientConnect()
        {
            while (true)
            {
                var clientSocket = _serverSocket.Accept();
                clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));
                var receiveThread = new Thread(ReceiveMessage);
                receiveThread.Start(clientSocket);
            }
        }

        /// <summary>
        /// 接收消息
        /// </summary>
        /// <param name="clientSocket"></param>
        private static void ReceiveMessage(object clientSocket)
        {
            var myClientSocket = (Socket)clientSocket;
            while (true)
            {
                try
                {
                    //通过clientSocket接收数据
                    var receiveNumber = myClientSocket.Receive(Result);
                    Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint, Encoding.ASCII.GetString(Result, 0, receiveNumber));
                }
                catch(Exception ex)
                {
                    Console.WriteLine(ex.Message);
                    myClientSocket.Shutdown(SocketShutdown.Both);
                    myClientSocket.Close();
                    break;
                }
            }
        }
    }
}

客户端代码：

using System;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;

namespace SocketClient
{
    class Program
    {
        private static readonly byte[] Result = new byte[1024];

        private static void Main()
        {
            //设定服务器IP地址
            var ip = IPAddress.Parse("127.0.0.1");
            var clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            try
            {
                clientSocket.Connect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口
                Console.WriteLine("连接服务器成功");
            }
            catch
            {
                Console.WriteLine("连接服务器失败，请按回车键退出！");
                return;
            }
            //通过clientSocket接收数据
            var receiveLength = clientSocket.Receive(Result);
            Console.WriteLine("接收服务器消息：{0}",Encoding.ASCII.GetString(Result,0,receiveLength));
            //通过 clientSocket 发送数据
            for (int i = 0; i < 10; i++)
            {
                try
                {
                    Thread.Sleep(1000);    //等待1秒钟
                    var sendMessage = "client send Message Help " + DateTime.Now;
                    clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));
                    Console.WriteLine("向服务器发送消息：{0}" + sendMessage);
                }
                catch
                {
                    clientSocket.Shutdown(SocketShutdown.Both);
                    clientSocket.Close();
                    break;
                }
            }
            Console.WriteLine("发送完毕，按回车键退出");
            Console.ReadLine();
        }
    }
