详解C# Socket简单例子(服务器与客户端通信)
这个例子只是简单实现了如何使用 Socket 类实现面向连接的通信。
注意:此例子的目的只是为了说明用套接字写程序的大概思路,而不是实际项目中的使用程序。在这个例子中,实际上还有很多问题没有解决,如消息边界问题、端口号是否被占用、消息命令的解析问题等。。
下面是两个程序的代码,(两个程序均为控制台程序)
先发服务端的(Server)完整代码如下:
引入命名空间:
using System.Net.Sockets;
using SystemNet;
using SystemThreading;
完整代码如下:
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 = IPAddressParse("1");
serverSocket = new Socket(AddressFamilyInterNetwork, SocketTypeStream, ProtocolTypeTcp);
serverSocketBind(new IPEndPoint(ip, myProt)); //绑定IP地址:端口
serverSocketListen(10); //设定最多10个排队连接请求
ConsoleWriteLine("启动监听{0}成功", serverSocketLocalEndPointToString());
//通过Clientsoket发送数据
Thread myThread = new Thread(ListenClientConnect);
myThreadStart();
ConsoleReadLine();
}
/// <summary>
/// 监听客户端连接
/// </summary>
private static void ListenClientConnect()
{
while (true)
{
Socket clientSocket = serverSocketAccept();
clientSocketSend(EncodingASCIIGetBytes("Server Say Hello"));
Thread receiveThread = new Thread(ReceiveMessage);
receiveThreadStart(clientSocket);
}
}
/// <summary>
/// 接收消息
/// </summary>
/// <param name="clientSocket"></param>
private static void ReceiveMessage(object clientSocket)
{
Socket myClientSocket = (Socket)clientSocket;
while (true)
{
try
{
//通过clientSocket接收数据
int receiveNumber = myClientSocketReceive(result);
ConsoleWriteLine("接收客户端{0}消息{1}", myClientSocketRemoteEndPointToString(), EncodingASCIIGetString(result, 0, receiveNumber));
}
catch(Exception ex)
{
ConsoleWriteLine(exMessage);
myClientSocketShutdown(SocketShutdownBoth);
myClientSocketClose();
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:
using SystemNet;
using SystemNetSockets;
using SystemThreading;
完整代码:
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 = IPAddressParse("1");
Socket clientSocket = new Socket(AddressFamilyInterNetwork, SocketTypeStream, ProtocolTypeTcp);
try
{
clientSocketConnect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口
ConsoleWriteLine("连接服务器成功");
}
catch
{
ConsoleWriteLine("连接服务器失败,请按回车键退出!");
return;
}
//通过clientSocket接收数据
int receiveLength = clientSocketReceive(result);
ConsoleWriteLine("接收服务器消息:{0}",EncodingASCIIGetString(result,0,receiveLength));
//通过 clientSocket 发送数据
for (int i = 0; i < 10; i++)
{
try
{
ThreadSleep(1000); //等待1秒钟
string sendMessage = "client send Message Hellp" + DateTimeNow;
clientSocketSend(EncodingASCIIGetBytes(sendMessage));
ConsoleWriteLine("向服务器发送消息:{0}" + sendMessage);
}
catch
{
clientSocketShutdown(SocketShutdownBoth);
clientSocketClose();
break;
}
}
ConsoleWriteLine("发送完毕,按回车键退出");
ConsoleReadLine();
}
}
}
编译成功后,先运行 服务端(server),再运行客户端(client)即可达到通信效果。
效果如下图:
该程序已在局域网测试通过。(192.168.X.X)
