填充数据表时，数据读取器是否比数据集更快? [英] Is datareader quicker than dataset when populating a datatable?

问题描述

哪个会更快.

1) 循环数据读取器并创建基于填充数据表的自定义行和列

1) Looping a datareader and creating a custom rows and columns based populated datatable

2) 或者创建一个 dataAdapter 对象并只(.Fill)一个数据表.

2) Or creating a dataAdapter object and just (.Fill)ing a datatable.

动态创建数据表后，数据读取器的性能是否仍然适用?

Does the performance of a datareader still hold true upon dynamic creation of a datatable?

推荐答案

DataAdapter 在幕后使用 DataReader，因此您的体验可能相同.

The DataAdapter uses a DataReader under the hood so your experience would likely be the same.

DataAdapter 的好处是您可以删除大量需要维护的代码.

The benefit of the DataAdapter is you cut out a lot of code that would need maintenance.
