下面写个控制台应用程序的最简单的Socket通信:
客户端:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;
namespace cccc_ConsoleClient_1
{
class Program
{
private static byte[] result = new byte[1024];
static void Main(string[] args)
{
//绑定服务器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));
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接受数据
int num = clientSocket.Receive(result);
Console.WriteLine("接收服务器消息:{0}", Encoding.ASCII.GetString(result, 0, num));
//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();
}
}
}
服务器:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;
namespace cccc_ConsoleServer_1
{
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clientsocket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 num = myClientSocket.Receive(result);
Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, num));
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
myClientSocket.Shutdown(SocketShutdown.Both);
myClientSocket.Close();
break;
}
}
}
}
}
运行之后的结果:
