分页带输出分页总数的方法

以下是一个分页查询,并返回数据总行数的存储过程的调用
   //查看详情
        public DataSet GetDetailExamInformation(int pageSize, int currentPage, string where, out int count)
        {
            OleDbParameter[] parameters = {
                            new OleDbParameter("@pageSize",OleDbType.Integer),
                            new OleDbParameter("@currentPage",OleDbType.Integer),
                            new OleDbParameter("@Where", OleDbType.VarChar,2000),
                            new OleDbParameter("@totalCount", OleDbType.Integer)
                                          };
            parameters[3].Direction = ParameterDirection.Output;
            parameters[0].Value = pageSize;
            parameters[1].Value = currentPage;
            parameters[2].Value = where == null ? "" : where;
            DataSet ds = OleDBHelper.RunProcedure("proc_Get_DetailExamInfomation", parameters, "tablename");
            count = int.Parse(parameters[3].Value.ToString());        //这个参数被赋值后会传出去
            return ds;
        }
当这个方法执行完成的时候,count会被赋值,分页的总数也就得到了。
