c# - Why is the value of only this variable ignored when constructing an object with {}? -

i have apirequest class on need default value isinbackground variable.

apirequest class simplified :

public class apirequest {     public string url;     public bool isinbackground = true; } 

when this, value of isinbackground ignored , set default :

apirequest rq = new apirequest{         url = "/user/suggest/" + pseudo,         isinbackground = false }; 

then log value , 'true', url right value...

the way set 'false' do

rq.isinbackground = false; 

then value indeed 'false'

so question why behave way ? because isinbackground has default value ?

public class apitest {     public string url;     public bool background = true; }  public class testclass : monobehaviour {     // use initialization    void start () {        apitest t = new apitest{           url = "coucou",           background = false       };        debug.log(" url: " + t.url + " background: " + t.background);   } } 

edit : after trying set default value 'false' , set variable 'true' problem doesn't occur...

edit show full code :

private void showpseudosuggestionsfor(string pseudo){     debug.log("get suggestions");     remoterequest r = remoterequest.getnewrequest("pseudosuggestions");     apirequest rq = new apirequest{         url = "/user/suggest/" + pseudo,         successcallback = onsuggestionsloaded,         successcallbackargs = new hashtable{             { "pseudo", pseudo }         },         isinbackground = false     };     //rq.isinbackground = false;     debug.log("isinbackground : " + rq.isinbackground);     r.setrequest(rq);     debug.log("isinbackground : " + rq.isinbackground);     r.sendrequest(); } 

full apirequest class :

this code fails in unity because use mono. bug found in using mono , has nothing c# language spoke44 pointed, solution use properties :
