How to get the IP address of the server on which my C# application is running on?

Question

I am running a server, and I want to display my own IP address.

What is the syntax for getting the computer\'s own (if possible, external) IP address?

Here is how i solved it. i know if you have several physical interfaces this might not select the exact eth you want.

private string FetchIP()
{
    //Get all IP registered
    List IPList = new List();
    IPHostEntry host;
    host = Dns.GetHostEntry(Dns.GetHostName());
    foreach (IPAddress ip in host.AddressList)
    {
        if (ip.AddressFamily == AddressFamily.InterNetwork)
        {
            IPList.Add(ip.ToString());
        }
    }

    //Find the first IP which is not only local
    foreach (string a in IPList)
    {
        Ping p = new Ping();
        string[] b = a.Split('.');
        string ip2 = b[0] + "." + b[1] + "." + b[2] + ".1";
        PingReply t = p.Send(ip2);
        p.Dispose();
        if (t.Status == IPStatus.Success && ip2 != a)
        {
            return a;
        }
    }
    return null;
}
