You might find the following snippet useful as a starter.

public static bool IsUserInGroup(string lanid, string group)
{
    DirectoryEntry entry = new DirectoryEntry("LDAP://" + LDAPPATH);
    if(entry != null)
    {
        entry.Username=@"LDAPUSER";
        entry.Password="LDAPPASSWORD";
        DirectorySearcher srch = new DirectorySearcher(entry);
        srch.Filter = String.Format("(&(objectClass=person)(sAMAccountName={0}))", lanid);
        srch.PropertiesToLoad.Add("memberOf");

        SearchResult result = srch.FindOne();
        if(result != null)
        {
            if(result.Properties.Contains("memberOf"))
            {
                string lookfor = String.Format("cn={0},", group.ToLower());
                foreach(string memberOf in result.Properties["memberOf"])
                {
                    if(memberOf.ToLower().StartsWith(lookfor))
                        return true;
                }
            }
        }
        return false;
    }
    throw new Exception(String.Format("Could not get Directory lanid:{0}, group{1}",   lanid, group));
}
