尝试这种方法,它适合我.

 public static string GetIPAddress()
    {
        IPHostEntry host;
        string localIP = "?";
        host = Dns.GetHostEntry(Dns.GetHostName());
        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily == AddressFamily.InterNetwork)
            {
                localIP = ip.ToString();
            }
        }
        return localIP;
    }

谢谢,
