调用分页存储过程

//调用
        public DataSet Query(string procName, ref int Total, SqlParameter[] sqlParameters)

            DataSet dataSet = new DataSet();
            using (SqlConnection connection = new SqlConnection(con))
            {
                //打开数据库
                connection.Open();
                //封装执行的sql语句
                using (SqlCommand command = new SqlCommand(procName, connection))
                {
                    //将存储过程的输入参数放到comand中
                    command.Parameters.AddRange(sqlParameters);
                    //指定执行的是存储过程
                    command.CommandType = CommandType.StoredProcedure;
                    //使用适配器关联command
                    SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(command);
                    //适配器填充数据
                    sqlDataAdapter.Fill(dataSet);
                    //获取输出参数
