Question

我在Windows窗体应用程序中使用TcpListener;它有一个“开始”按钮，可以启动TcpListener。但是，当我单击开始按钮时，将抛出以下异常：

请求的地址在其上下文中无效

这是我用来启动监听器的代码：

IPAddress FriendIp = IPAddress.Parse(IpAddress);
server = new TcpListener(FriendIp, PortNum);
server.Start();

这是异常的调用堆栈：

Harold和Spender是正确的，TcpListener只能绑定到实例化它的机器上的本地IP地址。

tcplistener无法启动
