Get IP of my machine C# with virtual machine installed

Question

I want to get the current IP address of the computer that has say 3 virtual machines (VM Ware) installed. I want to get LAN address of that computer.

current code that i have returns me an array but how to identify current computer lan address ?

public static string getThisCompIPAddress()
    {
        IPAddress[] addresslist = Dns.GetHostAddresses(Dns.GetHostName());
        return (addresslist[0].ToString());


    }

addresslist returns an array of 3 IP addresses

Answer 1

You could try the NetworkInterface class, and try to match the name or physical address of the LAN connection to find out the real one. Maybe searching within this class and it's members you can find something that suits your needs.

Here is a simple method to provide some usage info:

using System.Net.NetworkInformation;

...

static void ViewNetworkInfo()
{
    NetworkInterface[] networks = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface nw in networks)
    {
        Console.WriteLine(nw.Name);
        Console.WriteLine(nw.GetPhysicalAddress().ToString());

        IPInterfaceProperties ipProps = nw.GetIPProperties();
        foreach (UnicastIPAddressInformation ucip in ipProps.UnicastAddresses)
        {  
            Console.WriteLine(ucip.Address.ToString());
        } 

        Console.WriteLine();
     }
     Console.ReadKey();
}

public static ArrayList getThisCompIPAddress()
    {
        ArrayList strArrIpAdrs = new ArrayList();
        ArrayList srtIPAdrsToReturn = new ArrayList();
        addresslist = Dns.GetHostAddresses(Dns.GetHostName());
        for (int i = 0; i < addresslist.Length; i++)
        {
            try
            {
                long ip = addresslist[i].Address;
                strArrIpAdrs.Add(addresslist[i]);
            }
            catch (Exception ex) 
            {
                Console.WriteLine(ex.Message);
            }

        }

        foreach (IPAddress ipad in strArrIpAdrs)
        {

            lastIndexOfDot = ipad.ToString().LastIndexOf('.');
            substring = ipad.ToString().Substring(0, ++lastIndexOfDot);
            if (!(srtIPAdrsToReturn.Contains(substring)) && !(substring.Equals("")))
            {
                srtIPAdrsToReturn.Add(substring);
            }
        }

        return srtIPAdrsToReturn;
    }

this is 100% working, the real problem was that it was throwing error while calculating Address that returns long. Error Code is 10045
