                {
                    dirEntry.Properties["member"].Add(userPrincipal.DistinguishedName);
                    dirEntry.CommitChanges();
                    dirEntry.Close();
                }
            }

Use this code:

DirectoryEntry dirEntry = new DirectoryEntry("LDAP://" + group);
                if (dirEntry != null)
                {
                    dirEntry.Properties["member"].Add(userPrincipal.DistinguishedName);
                    dirEntry.CommitChanges();
                    dirEntry.Close();
                }

if the user have access to active directory it will work fine but if user dont have permission operation will failed
