给你一点例子吧~
5.点对点通信
/*
using System.Data;
using System.Net.Sockets;
using System.Net;
using System.Threading;
*/
Thread th;
TcpListener tpListen1;
bool listenerRun=true;
NetworkStream tcpStream;
StreamWriter reqStreamW;
TcpClient tcpc;
Socket skSocket;
protected void Listen()
{
try{
tpListen1=new TcpListener(Int32.Parse(%%2));
tpListen1.Start();
skSocket=tpListen1.AcceptSocket();
EndPoint tempRemoteEP=skSocket.RemoteEndPoint;
IPEndPoint tempRemoteIP=(IPEndPoint)tempRemoteEP;
IPHostEntry host=Dns.GetHostByAddress(tempRemoteIP.Address);
string HostName=host.HostName;
while(listenerRun)
{
Byte[] stream=new Byte[1024];
string time=DateTime.Now.ToString();
int i=skSocket.ReceiveFrom(stream,ref tempRemoteEP);
string %%5=Encoding.UTF8.GetString(stream);
//指定编码，从缓冲区中解析出内容
//time+" "+HostName+":"
}
}
catch(Security.SecurityException)
{
//防火墙安全错误！
}
try{
string sMsg=%%4;
string MyName=Dns.GetHostName();
reqStreamW=new StreamWriter(tcpStream);
reqStreamW.Write(sMsg);
reqStreamW.Flush();
string time=DateTime.Now.ToString();
//显示传送的数据和时间
//time+" "+MyName+":"
//sMsg
}
catch(Exception)
{
//无法发送信息到目标计算机！
}

protected override void Dispose(bool disposing)
{
try{
listenerRun=false;
th.Abort();
th=null;
tpListen1.Stop();
skSocket.Close();
tcpc.Close();
}
catch{}
if(disposing && component!=null)
{
components.Dispose();
}
}
base.Dispose(disposing);
}

1.简单服务器端
/*
using System.Data;
using System.Net.Sockets;
using System.Net;
using System.Threading;
*/
private static int port = %%2;
private static Thread thThreadRead;
private static TcpListener TcpListen;
private static bool bListener = true;
private static Socket stRead;
private static void Listen()
{
try
{
TcpListen = new TcpListener(port);
TcpListen.Start();
stRead = TcpListen.AcceptSocket();
EndPoint tempRemoteEP = stRead.RemoteEndPoint;
IPEndPoint tempRemoteIP = (IPEndPoint)tempRemoteEP;
IPHostEntry host = Dns.GetHostByAddress(tempRemoteIP.Address);
string sHostName = host.HostName;
while (bListener)
{
stRead.Send(Encoding.ASCII.GetBytes("Hello"));
string sTime = DateTime.Now.ToShortTimeString();
Byte[] byRead = new Byte[1024];
int iRead = stRead.ReceiveFrom(byRead, ref tempRemoteEP);
Byte[] byText = new Byte[iRead];
Array.Copy(byRead, 0, byText, 0, iRead);
string line = System.Text.Encoding.Default.GetString(byRead);
}
}
catch (System.Security.SecurityException)
{
//监听失败
}
}
thThreadRead = new Thread(new ThreadStart(Listen));
thThreadRead.Start();

2.简单客户端
/*
using System.Data;
using System.Net.Sockets;
using System.Net;
*/
private static IPEndPoint dateTimeHost;
string hostIPString=%%1;
string hostPortString=%%2;
IPAddress hostIP=IPAddress.Parse(hostIPString);
dateTimeHost=new IPEndPoint(hostIP,Int32.Parse(hostPortString));
Socket conn=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
conn.Connect(dateTimeHost);
int bytes=0;
Byte[] RecvBytes=new Byte[256];
bytes=conn.Receive(RecvBytes,RecvBytes.Length,0);
string RecvString=Encoding.ASCII.GetString(RecvBytes,0,bytes);
Console.WriteLine(RecvString);
conn.Shutdown(SocketShutdown.Both);
conn.Close();

3.获得本机IP
//using System.Net;
IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
string %%1=null;
for (int i = 0; i < addressList.Length; i++)
{
%%1 += addressList[i].ToString();
}

你试试ping一下通不通，可能是防火墙的问题。还要尤其注意windows防火墙，还有些杀毒软件也会阻止一些程序，而且关掉还不行。方法就是添到白名单里，或者卸载。。。

另外服务端写一个日志输出的功能
客户端登录的时候跟踪调试一下

不用试，本机下可以，两台机器不行，肯定就是防火墙的问题。

你这也没代码 就按楼上的都试下
