java - How to Extract JSON value outside of Array -

-

at moment can loop through json array ''pos" , store variables within array list.

what i'm trying do:

how can parse tour & date outside "pos" array?

i store values in "tour" & "date" 2 separate string variables.

my understanding: json.getjsonarray() can't used in case, json.getjsonarray(tag_messages); pulls in "pos" array data.

json structure:

{     "pos": [         {             "pos": "",             "person": "",             "thur": "",             "score": "",             "round": ""        },         {             "pos": "2",             "person": "john",             "thur": "",             "score": "16",             "round": "3"        },        {             "pos": "3",             "person": "peter lynch",             "thur": "",             "score": "5",             "round": "2"        }     ],     "tour": "camping",     "date": "thursday jul 23 - sunday jul 26, 2015"   }

code parse json pos array:

 // json nodes private static final string tag_messages = "pos"; private static final string tag_id = "pos"; private static final string tag_from = "person"; private static final string tag_email = "thur"; private static final string tag_subject = "round"; private static final string tag_date = "score";   // these outside of array pos     private static final string tag_tour = "tour"; private static final string tag_tourdate = "date";     try {             inbox = json.getjsonarray(tag_messages);              inbox.tostring();               // looping through messages             (int = 0; < inbox.length(); i++) {                 jsonobject c = inbox.getjsonobject(i);                  // storing each json item in variable                 string id = c.getstring(tag_id);                 // creating new hashmap                 hashmap<string, string> map = new hashmap<string,    string>();                  // adding each child node hashmap key => value                 map.put(tag_id, id);                 map.put(tag_from, from);                 map.put(tag_email, mailer);                 map.put(tag_date, date);                 map.put(tag_subject, subject);                  // adding hashlist arraylist                 inboxlist.add(map);

as can jsonarray json , can string too.

something :

json.getstring("tour"); json.getstring("date");

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
