tcplistener没有启动

Question

我在Windows应用程序中使用TcpListener；该应用程序有一个启动TcpListener的“开始”按钮。但是，当我单击“开始”按钮时，将引发以下异常：

请求的地址在其上下文中无效

这是我用来启动侦听器的代码：

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

这是异常的调用堆栈：

哈罗德和斯彭德是正确的，TcpListener只能绑定到被实例化的机器上的本地IP地址。
