而且还有AndAlso，表现？

问题描述

我很好奇是否有人知道And / AndAlso和

Or / OrElse的组合在性能方面的比较。

这需要更多的系统工作对And

进行两次评估或对AndAlso进行短路？


纯粹是为了启蒙。


提前谢谢。

解决方案

我更喜欢''AndAlso''/''OrElse''应该进行逻辑操作。

在许多情况下短路更快，因为通常不需要评估部分

表达式。

I was just curious if anyone knows how the combinations of And/AndAlso and
Or/OrElse compare in terms of performance.
Which takes more work for the system, performing two evaluations on an And
or performing short-circuiting on an AndAlso?

Purely for enlightenment.

Thanks in advance.

解决方案

I would prefer ''AndAlso''/''OrElse'' when a logical operation should be done.
Short circuiting is faster in many cases, because often parts of the
expression don''t need to be evaluated.
