c# - does, myval = (someconditon) ? someVal : myval get optimized to not set the value in case it's false -

- 

cpath = (cpath == null) ? request.path : cpath;

first of wish clr let me ? request.path , not bother me creating :

but i'm asking optimize away? or still assign.

well, write as:

if (cpath == null) {     cpath = request.path; }

to make clearer. alternative (as mentioned elsewhere) is

cpath = cpath ?? request.path;

but why care if there's assignment? really think that's going significant performance hit?

note if cpath field rather local variable, potentially make difference - because value of cpath change between first check , second evaluation, , again between evaluation , assignment. whether noticed depends on caching etc, it's not simple might @ first.
