Return two parameter from stored procedure

Suppose in stored procedure we have like this

set @lastinserted=(select ident_current('user_referencerecord'))
 set @exist=0
Now to return two variables
select @exist as exist,@lastinserted as lastinserted

To recieve at .cs page

using (SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
            {
                while (rdr.Read())
                {
                    returnval1=rdr.GetInt32(rdr.GetOrdinal("exist"));
                    int returnval2 = rdr.GetInt32(rdr.GetOrdinal("lastinserted"));
                }


            }
