C#如何获取真实的IP地址~

Question

请教一下~

Answer 1

                IPEndPoint ipep = new IPEndPoint(IPAddress.Any, TcpPort);

Answer 2

IPEndPoint ipep = new IPEndPoint(IPAddress.Any, TcpPort);
The name 'TcpPort' does not exist in the current context报错

Answer 3

string str1=System.Net.Dns.GetHostName;   
System.Net.IpHostEntry   hostinfo=System.Net.Dns.GetHostByName(str1);   
System.Net.IpAddress   add1=hostinfo.AddressList[0];   

Answer 4

刚才发错了.你试试这个.
            string myIP, myMac;
            System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
            if (addressList.Length > 1)
            {
                myIP = addressList[0].ToString();
                myMac = addressList[1].ToString();
            }
            else
            {
                myIP = addressList[0].ToString();
            }
            Console.WriteLine(myIP);
            Console.ReadKey();
要引用system.net   

Answer 5

string myIP;
            IPAddress[] ipList = Dns.GetHostAddresses(Dns.GetHostName());
            myIP = ipList[0].ToString();
            Console.WriteLine(myIP);
            Console.ReadKey();

Answer 6

获得客户端Socket
然后:
Socket.RemoteEndPoint

Answer 7

  public string GetIp()
        {
            System.Net.WebClient client = new System.Net.WebClient();
            client.Encoding = System.Text.Encoding.Default;
            string reply = client.DownloadString("http://www.ip138.com/ip2city.asp");
            int start = reply.IndexOf("[");
            int end = reply.IndexOf("]");
            return reply.Substring((start + 1), (end - start - 1));
        } 

Answer 8

万一http://www.ip138.com/ip2city.asp这个地址失效了~~不就没有用了~
