I've linked right to the code you will need. The code (in case the link ever breaks) is as follows:

public ArrayList Groups()
{
    ArrayList groups = new ArrayList();
    foreach (System.Security.Principal.IdentityReference group in
        System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups)
    {
        groups.Add(group.Translate(typeof
            (System.Security.Principal.NTAccount)).ToString());
    }
    return groups;
}
