C#Tcp服务端与客户端接收消息与发送消息

服务端的搭建

using System.Net;

namespace TCP服务器
{
    class Program
    {
        static void Main(string[] args)
        {
            //第一步创建socket对象 服务端
            Socket serverSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
            //第二步绑定ip和端口号
            //这是自身电脑的ip，Parse可以直接转换为IPAddress的对象出去
            IPAddress ipAddress = IPAddress.Parse("192.168.1.105");
            //92代表端口号
            IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 92);
            //绑定
            serverSocket.Bind(ipEndPoint);
            //开始监听端口号
            serverSocket.Listen(0);

            //创建客户端
            Socket clientSocket = serverSocket.Accept();//接受一个客户端连接

            //选客户端发送一条消息
            string msg = "Hello client! 你好.....";
            //System.Text.Encoding.UTF8.GetBytes将一个字符串转为byte的序列
            byte[] data = System.Text.Encoding.UTF8.GetBytes(msg);
            clientSocket.Send(data);

            //接受客户端的一条消息
            byte[] dataBuffer = new byte[1024];//用来接受数据
            //接收到的消息将存入dataBuffer中，返回接收到了多少个数据
            int count = clientSocket.Receive(dataBuffer);
            //0到count个数据的内容
            string msgReceive = System.Text.Encoding.UTF8.GetString(dataBuffer,0,count);
            Console.WriteLine(msgReceive);

            //在客户端反馈消息后，暂停下
            Console.ReadKey();
            //先关闭客户端，在关闭服务端
            clientSocket.Close();
            serverSocket.Close();
        }
    }
}

客户端的搭建

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Net;

namespace TCP客户端
{
    class Program
    {
        static void Main(string[] args)
        {

            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //服务端链接ip与端口号
            clientSocket.Connect(new IPEndPoint(IPAddress.Parse("192.168.1.105"), 92));

            byte[] data = new byte[1024];
            int count = clientSocket.Receive(data);
            string msg = Encoding.UTF8.GetString(data, 0, count);
            Console.Write(msg);


            string s = Console.ReadLine();
            Console.Write(s);
            clientSocket.Send(Encoding.UTF8.GetBytes(s));

            Console.ReadKey();
            clientSocket.Close();
        }
    }
}
