Question

我已经在Windows 10 Pro下的C＃中创建了一个TCP套接字，但是当我尝试使用Connect()方法时，它失败了，并说连接被拒绝。我试图关闭Windows防火墙，但是它根本没有帮助。

_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
_socket.setSocketOption(SocketOptionLevel.Tcp, SocketOptionName.NoDelay, true);
_socket.SendTimeout = 2000;
_socket.ReceiveTimeout = 2000;

IPHostEntry ipHost = Dns.Resolve("localhost");
IPAddress ipAddr = ipHost.AddressList[0];

//IPEndPoint ipEnd = new IPEndPoint(IPAddress, TCPPort);
//_socket.Connect(ipEnd);
_socket.Connect(new IPEndPoint(IPAddress, TCPPort));

c＃服务器套接字创建IPEndPoint 127.0.0.1，“连接被拒绝”，错误代码：10061
