C# 获取IP地址

      public List ipList { get; set; } 
 private void GetIP()
        {
            ipList = new List();
            string hostName = Dns.GetHostName();//本机名   
            //System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，   //我运行时且只返回了一个IPv4的地址   
            System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6   
            foreach (IPAddress ip in addressList)
            {
                if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                    ipList.Add(ip.ToString());
            }
            if (ipList.Count > 0)
            {
                ipComboBox.SelectedIndex = 0;
            }
        }
