代码性能 [英] Code Performance

问题描述

每隔一段时间我都会读到类似的内容：

"使用像File.Exists这样的防御性代码技术代替Try和

Catch因为它少了性能猪


当我编程时，我显然对如何编码

不同部分有不同的想法。那么如何从表演中找出最好的？b
观点？

Every so often I read something like:
"use a defensive code technique like File.Exists instead of a Try and
Catch because it''s less of a performance hog"

And when I program, I obviously have different ideas on how to code
different sections. So how to I findout what''s best from a performance
point-of-view?

推荐答案

测试和阅读。


您是否了解这个

场景中防御性编码技术的含义？

是的，但有没有办法找出两组相同代码之间的性能差异？

Yep, but is there a way of finding out the difference in performance
between two sets of the same code?
