C#

I'm trying to write a program to find out what an iplogger's destination is like the one's you see goo.gl/???? and the only method I can find involves GET and you cannot use GET on link pointers. Sorry this may sound like a dumb question, I'm still a beginner at programmer and have been teaching myself.
So here is what I used but it involves GetResponse-

HttpWebRequest connection = (HttpWebRequest)WebRequest.Create(textBox8.Text);
connection.Method = WebRequestMethods.Http.Head;
connection.MaximumAutomaticRedirections = 2;
connection.AllowAutoRedirect = true;
HttpWebResponse response = (HttpWebResponse)connection.GetResponse();
textBox1.Text = ("redirected to: " + response.GetResponseHeader("Location"));
response.Close();

I Tried using a webBrowser but it got messy.
