socket.bind(myserver) 错误提示提供了无效参数？？？？在线结贴

if (myServer == null)
{
myServer = new IPEndPoint(IP, Port);
socketlistener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
}
while (!isConnected)
{
try
{
socketlistener.Bind(myServer);
socketlistener.Listen(0);
isConnected = true;
thread = new Thread(new ThreadStart(target));//监听命令
thread.Start();
textBox1.AppendText("侦听已开始！");
}

为什么IP跟端口一样，第二次Bind时会出现提供参数无效异常？？？

代码没有问题啊，你是不是 Bind 了两次
