MS数据访问应用程序块（daab）与ado.net数据读取器的性能比较如何

Question

I am going to use the DAAB to prevent a lot of manual labor in my database intensive application. But before I get started I would like to know if there would be any noticeable perfoemce differences between using the native ado.net datareader and the DAAB.

Answer 1

Most of your performance hit is going to be in the database reads/writes. That's true whether you use ADO.NET or DAAB, or any other DAL for that matter.
