asp.net C# Socket 服务器与客户端通信实现代码

作者：袖梨 2022-06-25

先发服务端的（Server)完整代码如下：

引入命名空间：

代码如下	复制代码
using System.Net.Sockets; using System.Net; using System.Threading;

完整代码如下：

代码如下

复制代码

namespace SocketServer
{
    class Program
    {
        private static byte[] result = new byte[1024];
        private static int myProt = 8885;   //端口
        static Socket serverSocket;
        static void Main(string[] args)
        {
            //服务器IP地址
            IPAddress 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.ToString());
            //通过Clientsoket发送数据
            Thread myThread = new Thread(ListenClientConnect);
            myThread.Start();
            Console.ReadLine();
        }

        ///

/// 监听客户端连接
///

        private static void ListenClientConnect()
        {
            while (true)
            {
                Socket clientSocket = serverSocket.Accept();
                clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));
                Thread receiveThread = new Thread(ReceiveMessage);
                receiveThread.Start(clientSocket);
            }
        }

        ///

/// 接收消息
///

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

以上是服务端（server）的完整代码。

客户端（Client）的完整代码如下：

引入命名空间：

代码如下	复制代码
using System.Net; using System.Net.Sockets; using System.Threading;

完整代码：

代码如下

复制代码

namespace SocketClient
{
    class Program
    {
        private static byte[] result = new byte[1024];
        static void Main(string[] args)
        {
            //设定服务器IP地址
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            Socket 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
            int 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
                    string sendMessage = "client send Message Hellp" + 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();
        }
    }
