i pulling data 3rd party api , have myself code looks this...

public partial class form1 : form {     int playsystem = 2;     string playid = "";      public form1()     {         initializecomponent();     }      private void xbox_checkedchanged(object sender, eventargs e)     {         playsystem = 1;     }      public void playstation_checkedchanged(object sender, eventargs e)     {         playsystem = 2;     }      private async void searchbutton_click(object sender, eventargs e)     {         statdisplay.clear();          var username = namebox.text;          using (var client = new httpclient())         {             client.defaultrequestheaders.add("x-api-key", "xxxxxxxxxxxxxxxx");              var response = await client.getasync("https://bungie.net/platform/destiny/searchdestinyplayer/" + playsystem + "/" + username);             var content = await response.content.readasstringasync();             dynamic item = newtonsoft.json.jsonconvert.deserializeobject(content);              statdisplay.appendtext(item.tostring());         }     } }

instead of displaying information in object string, take specific value object, store variable, , use variable in httprequest.

the output getting looks this...

{   "response": [     {       "iconpath": "/img/theme/destiny/icons/icon_psn.png",       "membershiptype": 2,       "membershipid": "01234567890",       "displayname": "xxxxxxxxxx"     }   ],   "errorcode": 1,   "throttleseconds": 0,   "errorstatus": "success",   "message": "ok",   "messagedata": {} }

i focus on membershipid key/value.

var membershipid = (string)item.response[0].membershipid;

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
