希望对vb.net源码实例你有帮助
400分求vb.net,求一个socket的编程实例，详细见问题补充：至少需要
Imports System
Imports System.Net
Imports System.Net.Sockets
Imports System.Threading
Imports System.Text
还要了解异步与委托
简单点的话
sub tcplisten() '监听过程
Const LPort As Integer = 6850 '本地监听端口
Dim IPadd As IPAddress = Dns.GetHostEntry(Dns.GetHostName()).AddressList(1) ’本地IP
'addresslist里面包括IPV6和IPV4
Dim IPEP As New IPEndPoint(IPadd, LPort) '结点
TCPL = New TcpListener(IPEP) ’建立监听实例
TCPL.Start() '开始监听
If TCPL.Pending = True Then '如果有连接接入
Dim TCPLX As New Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp) '建立一个新的SOCKET
TCPLX=TCPL.Accept() ’将第一个接入挂起的连接传给新建SOCKET ， 因为监听的SOCKET还要继续监听
dim Ripep asnew ipendpoint=TCPLX.RemoteEndPoint '此时获得远程的ip与端口号
listbox.add(ripep.ip)
dim buff as byte()
buff=TCPLX.Receive() 'listenacceptrecieve这时候可以接受数据了
dim s as string=Encoding.Default.GetString(buff) '转换成文本
msg "s"
TCPLX.send(buff) '这个是发送
end if
End Sub
长时间没写 ， 可能有点小错误，你自己调试调试，大概步骤就是listenacceptrecieve，最好看看msdn，那个学起来才系统
