求一个简单的基于TCP/IP的Socket通讯例子

[倒大霉的上帝]

如题:求一个简单的基于TCP/IP的Socket传输例子。要求有客户端和服务器端两个程序。可传输文字和文件。
谢谢各位大虾！

MSDN里，搜索一下，Socket编程

[j_f0001]

服务器端： s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
s.Bind(new IPEndPoint(IPAddress.Any, 8089));
s.Listen(0);
while (true)
{
Socket c = s.Accept();
byte[] buff = new byte[c.EndReceive];
c.BeginReceive(buff, 0, buff.Length, SocketFlags.None, new AsyncCallback(SendCallBack), "dd");
string str = Encoding.UTF8.GetString(buff);

}

客户端： c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
c.Connect(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8089));
string str = "this is a temp";
byte[] buff = Encoding.UTF8.GetBytes(str);
c.Send(buff, 0, buff.Length, SocketFlags.None, new AsyncCallback(SendCallBack),"dd");
