如何使用套接字编程获取客户端IP c＃

Question

Is there anyone who knows how to get client IP address using socket programming while we are requesting the access of file transferring?? I am using C#.

Answer 1

Socket.LocalEndPoint或Socket.RemoteEndPoint应该可以解决问题，具体取决于您是否是客户端。

Answer 2

In order to get the actual IP address:

// Using the RemoteEndPoint property.
Console.WriteLine (
"I am connected to " + IPAddress.Parse (((IPEndPoint)s.RemoteEndPoint).Address.ToString ()) + 
"on port number " + ((IPEndPoint)s.RemoteEndPoint).Port.ToString ());

// Using the LocalEndPoint property.
Console.WriteLine (
"My local IpAddress is :" + IPAddress.Parse (((IPEndPoint)s.LocalEndPoint).Address.ToString ()) +
"I am connected on port number " + ((IPEndPoint)s.LocalEndPoint).Port.ToString ());

Answer 3

Assuming you have a TcpListener , after the AcceptSocket call you are returned a Socket . On this socket you can call RemoteEndPoint
