.net - Disable compiler optimisation for a specific function or block of code (C#) -

-

the compiler great job of optimising release builds, can useful ensure optimisation turned off local function (but not entire project unticking project options > optimize code).

in c++ achieved using following (with #pragma commented out):

#pragma optimize( "", off ) // code such function (but not whole project) #pragma optimize( "", on )

is there equivalent in c#?

update

several excellent answers suggest decorating method methodimploptions.nooptimization. implemented in .net 3.5, though not in compact framework (cf) version. related follow-on question whether equivalent for:

* projects targeting .net 3.0 or earlier? * projects deployed device such windows ce 6.0 using .net 3.5 cf?

you can decorate specific method (or property getter/setter) [methodimpl(methodimploptions.nooptimization)] , [methodimpl(methodimploptions.noinlining)], prevent jitter optimizing , inlining method:

[methodimpl(methodimploptions.nooptimization | methodimploptions.noinlining)] private void methodwhichshouldnotbeoptimized() { }

however, there isn't way apply attribute block of code. nooptimization attribute added in .net 3.5, might important legacy code or compact framework.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
