Get local IP address

Question

In the internet there are several places that show you how to get an IP address. And a lot of them look like this example:

String strHostName = string.Empty;         


        

Answer 1

Refactoring Mrcheif's code to leverage Linq (ie. .Net 3.0+). .

private IPAddress LocalIPAddress()
{
    if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
    {
        return null;
    }

    IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());

    return host
        .AddressList
        .FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork);
}
