.net - Is there any benefit on declaring a local constant of string over a local variable C# -


is there noticeable benefit regarding performance on using constant on string. suppose following case

public void methodusingconstant() {   const string searchedtext = "foo";    //some operations using searchedtext string }  public void methodnousingconstant() {   string searchedtext = "foo";    //some operations using searchedtext string }

there option take class-struct constant field.

or, should avoid overthink these micro optimizations?

if think it, shouldn't different. because when computer sees variable, retrieves memory adress , value. have tried code , difference tiny (less 3ms: btw code ran in ~107 ms) down millions of other variables:

        //just changed non const         const string s = "hello";          string full = "";          int k = 0;          for(int = 0; < 10000; i++)         {             full += s;         }

in general, const vs non const comes down this: value stay same: set const, else leave it. here great link .net optimization.

to sum up, should these tiny details moment code can't optimized in other way, , when case, code fine.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
