c# - TcpListener TcpClient 获取 IPAddress

Question

我希望从中获取IPAddress

服务器端

TcpListener ftp_listener = new TcpListener(IPAddress.Any, ftpport);
 newclient = listener.AcceptTcpClient();

请问如何找到newclient ipaddress

客户端

TcpClient ftpclient = new TcpClient();
 ftpclient.Connect(ipAddress, ftpport);

如何找到ftpclient ipaddress

目前我正在使用

 TcpClient ftpclient = new TcpClient();

            //get IpAddress of Server
#pragma warning disable CS0618 // Type or member is obsolete
            IPAddress ipAddress = Dns.Resolve("localhost").AddressList[0];
#pragma warning restore CS0618 // Type or member is obsolete

            ftpclient.Connect(ipAddress, ftpport);// "192.168.1.160", ftpport);

有没有更好的办法 ...

谢谢

对于服务器和客户端，获取远程端点（IP 地址和端口）的方法是相同的。

1. 获取服务器上的客户端 IP 地址：

   IPEndPoint remoteIpEndPoint = newclient.Client.RemoteEndPoint as IPEndPoint;
   Console.WriteLine("Client IP Address is: {0}", remoteIpEndPoint.Address);
   

2. 获取客户端上的服务器 IP 地址：

       IPEndPoint remoteIpEndPoint = ftpclient.Client.RemoteEndPoint as IPEndPoint;
       Console.WriteLine("FTP Server IP Address is: {0}", remoteIpEndPoint.Address);
