在C＃中使用DeMorgan定理在条件语句中手动优化布尔表达式（例如if条件）是有用的， [英] Is it useful in C# to apply DeMorgan's theorem to manually optimize boolean expressions in conditional statements (e.g. if conditions)

问题描述

回到我在C和C ++中做大部分工作的那一天，当然，我会手动应用 deMorgan定理来优化任何非平凡的布尔表达式。

Back in the day when I did most of my work in C and C++, as a matter of course, I would manually apply deMorgan's theorem to optimize any non-trivial boolean expressions.

在C＃中这样做是有用的， ？

Is it useful to do this in C# or does the optimizer render this unnecessary?

推荐答案

在处理器上这种快速，实际上不可能重新布置布尔表达式使速度有任何实际差异。而C＃编译器是非常聪明的，它会优化它。优化可读性和清晰度！

On processors this fast, it's virtually impossible for rearranging boolean expressions to make any actual difference in speed. And the C# compiler is very smart, it will optimize it as well. Optimize for readability and clarity!
