1.新建一个控制台工程，代码如下

        static void Main(string[] args)        {            // 定义IP地址            IPAddress address = IPAddress.Loopback;            IPEndPoint endPoint = new IPEndPoint(address, 50000);            // 创建socket对象            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            // bind            socket.Bind(endPoint);            // listen            socket.Listen(10);            Console.WriteLine("开始监听，端口号：{0}", endPoint.Port);            while (true)            {                // accept                Socket clientSocket = socket.Accept();                Console.WriteLine("建立了一个连接,对方端点{0}", clientSocket.RemoteEndPoint);                // 开始接受对方的信息,并显示                byte[] buffer = new byte[4096];                int length = clientSocket.Receive(buffer, 4096, SocketFlags.None);                System.Text.Encoding utf8 = System.Text.Encoding.UTF8;                string requestString = utf8.GetString(buffer, 0, length);                Console.WriteLine(requestString);                                // 发送响应信息                string statusLine = "HTTP/1.1 200 OK\r\n";                byte[] statusLineBytes = utf8.GetBytes(statusLine); // 状态行                string responseBody = "<html><head><title>response server</title></head><body>hello world!</body></html>";                byte[] responseBodyBytes = utf8.GetBytes(responseBody);//   内容部分                string responseHeader = String.Format("Content-Type: text/html;charset=UTF-8\r\nContent-Length:{0}\r\n",                                                                                        responseBody.Length);                byte[] responseHeaderBytes = utf8.GetBytes(responseHeader);//  回应头                //  发送消息                clientSocket.Send(statusLineBytes);                clientSocket.Send(responseHeaderBytes);                clientSocket.Send(new byte[] { 13, 10 });                clientSocket.Send(responseBodyBytes);                // 断开与客户端的连接                clientSocket.Close();                if (Console.KeyAvailable)                {                    break;                }                      }            socket.Close();        }

2.运行该工程

3.打开浏览器在地址栏中输入http://localhost:50000/ ，用httpwatch可大概了解浏览器与服务器的简要流程
