c# - Detect 100% CPU load by a referenced library -

-

i have asp.net (c#) website uses third party dll process data users post via web form. call pretty straightforward: 

string result = thirdpartylib.processdata(mystring);

once in blue moon library hangs , (according hosting provider logs) consumes 100% of cpu. website hosted on shared hosting, have no access iis or event logs. when happens, website automatically stopped hosting provider performance monitor, , have manually switch on.

now, know right thing to investigate problem , fix (or replace) dll. it's third-party software, unuable fix it, , support not helpful @ all. moreover, can't reproduce problem. replacing library pain too.

is there way in c# detect when dll starts consuming 100%cpu , kill process automatically asp.net code?

you cannot "detect" if current process hanging because caller of method (third party or not) you're not in control until returns.

what can move call third party library separate executable , have output result via standard output (you can use console.writeline(string) this).

once you've done that, can start separate process runs executable, read result via standardoutput , use waitforexit(int) wait amount of time (maybe few seconds) process finish. return value of waitforexit() tells if process exited. in case didn't, can kill() , move on without iis worker process hanging whole.

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
