Is it useful in C# to apply DeMorgan's theorem to manually optimize boolean expressions in conditional statements (e.g. if conditions)

Question

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.

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

Answer 1

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!
