小弟我想做一个聊天程序，但对SOCKET不懂，有哪位大哥有相关示例我吗？或相关网站，谢谢!

Question

MSDN中有这个的EXAMPLE的.
去看看吧.

Answer 1

给你一个例子：using System;
using System.Net.Sockets;
using System.Net;
using System.Text;
using System.IO;namespace SimplestChatConsole
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
private Socket soc;
private Socket clientSoc;
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
//
// TODO: Add code to start application here
//
Class1 example;
bool isServer=false;
System.Console.Out.WriteLine("Is the endpoint the server?\nY/N");
char c=(char)System.Console.Read();
if(c=='y'||c=='Y')
isServer=true;
example=new Class1(isServer);
if(isServer)
example.ServerSide();
else
example.ClientSide();
} public Class1(bool isServer)
{
IPEndPoint ep;
IPAddress ip=Dns.GetHostByName("localhost").AddressList[0];
if(isServer)
ep=new IPEndPoint(ip,999);
else
ep=new IPEndPoint(ip,998);
soc=new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);
soc.Bind(ep);
} public void ServerSide()
{
int count;
soc.Listen(1);
System.Console.WriteLine("Begin Listening...");
clientSoc=soc.Accept();
System.Console.WriteLine("Got a client");
System.Console.ReadLine();
string input="Hello";
byte[] buf=new byte[1024];
while(input!="\\q")
{
clientSoc.Send(Encoding.Default.GetBytes(input));
count=clientSoc.Receive(buf);
System.Console.WriteLine(Encoding.Default.GetString(buf,0,count));
input=System.Console.ReadLine();
}
clientSoc.Close();
soc.Close();
} public void ClientSide()
{
int count;
IPEndPoint ep;
byte[] buf=new byte[1024];
IPAddress ip=Dns.GetHostByName("localhost").AddressList[0];
ep=new IPEndPoint(ip,999);
soc.Connect(ep);
if(soc.Connected)
System.Console.WriteLine("Successfully Connected to the Server");
string input="Hello";
System.Console.ReadLine();
while(input!="\\q")
{
count=soc.Receive(buf);
System.Console.WriteLine(Encoding.Default.GetString(buf,0,count));
input=System.Console.ReadLine();
soc.Send(Encoding.Default.GetBytes(input));
}
soc.Close();
}
}
}
