Get IP from host in C#

hi i am wanting to get the ip of a host, the code I found is this:

    string howtogeek = "www.google.com";
    IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);
    foreach (IPAddress theaddress in addresslist)
    {
        test.AppendText(theaddress.ToString() + Environment.NewLine);
    }

the problem is that I only get the first IP found without using foreach because I just want the first one, anyone can help me?

The first IP address will be 

string howtogeek = "www.google.com";
IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);
IPAddress firstAddress = addresslist[0];

Normally a machine can have multiple ip addresses. If there is only one network adapter XX there will be at least two ip's: the network adapter XX ip and the loopback 127.0.0.1. That say, you can use the following code to get the first IP:

string howtogeek = "www.google.com";
IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);
if(addresslist.Lengt > 0){
   test.AppendText(addresslist[0].ToString() + Environment.NewLine);
}

You could just use:

string howtogeek = "www.google.com";
IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);
var firstIp = addresslist[0];

Depending on the framework you are using, you can also use Enumerable.FirstOrDefault().

string howtogeek = "www.google.com";
IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);
var firstIp = addresslist.FirstOrDefault();
