public static string GetIpAddress()  // Get IP Address
{
    string ip = "";
    IPHostEntry ipEntry = Dns.GetHostEntry(GetCompCode());
    IPAddress[] addr = ipEntry.AddressList;
    ip = addr[2].ToString();
    return ip;
}
public static string GetCompCode()  // Get Computer Name
{
    string strHostName = "";
    strHostName = Dns.GetHostName();
    return strHostName;
}

string IP = GetIP();

    public string  GetIP()
    {
        string Str = "";
        Str = System.Net.Dns.GetHostName();
        IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(Str);
        IPAddress[] addr = ipEntry.AddressList;
        return addr[addr.Length - 1].ToString();

    }
