您可以从System.Net.Sockets.TcpClient检索主机名和端口吗？

Question

是否可以从新的TcpClient检索底层主机名/端口？

TcpListener listener = new TcpListener(IPAddress.Any, port);
TcpClient client = listener.AcceptTcpClient();
// get the hostname
// get the port

我在client.Client(a System.Net.Socket)中绕过,但在那里也找不到任何东西.有任何想法吗？

谢谢大家.

未经测试,但我会尝试以下方法:

TcpListener listener = new TcpListener(IPAddress.Any, port);
TcpClient client = listener.AcceptTcpClient();

IPEndPoint endPoint = (IPEndPoint) client.Client.RemoteEndPoint;
// .. or LocalEndPoint - depending on which end you want to identify

IPAddress ipAddress = endPoint.Address;

// get the hostname
IPHostEntry hostEntry = Dns.GetHostEntry(ipAddress);
string hostName = hostEntry.HostName;

// get the port
int port = endPoint.Port;

如果您可以使用IPAddress,我会跳过反向DNS查找,但您明确要求输入主机名.
