c# - foreach loop to fetch JSON value -

i trying fetch latitude , longitude of json result.

json result (have many records):

"results" : [   {      "geometry" : {         "location" : {            "lat" : 28.637255,            "lng" : 77.05202800000001         }      },      "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png",      "id" : "aef56d078ec3fcab6f4a966bd944d3d59973bd72",      "name" : "homeopati kendra",      "opening_hours" : {         "open_now" : false,         "weekday_text" : []      },      "place_id" : "chijqavdfrwfdtkrmrahjcbioni",      "reference" : "cnrjaaaawcobegdvsl4keqnpyt2osvf82b7fchipuhrfqvgg8b1er7fcv9i1nupn0lff50ovg9ug1pevkczg813lq9aae1dk5gcgn99ajpq1it9lafcwx3sauwtiinliepgptdhnz3ngdzhpvix70a2d1kzcchiqvd4os73_jmr2wyqg4jtrjxoujcngt2m4xzdixadjotga-lgrnr4",      "scope" : "google",      "types" : [ "hospital", "health", "establishment" ],      "vicinity" : "c-29 , vikas nagar,uttam nagar, vikas nagar extn, hastsal, new delhi"   }, 

for particular record (say record first):

jobject obj = jobject.parse(googleresult); jarray jarr = (jarray)obj["results"]; double lt = (double)jarr[0]["geometry"]["location"]["lat"]; double lg = (double)jarr[0]["geometry"]["location"]["lng"]; 

for fetching records:

foreach(var item in jarr) { double lt = convert.todouble(item[jarr["geometry"]["location"]["lat"]]); } 

for fetching 1 record works fine records not working.

you can use selecttokens pick out fields of interest json. since method supports jsonpath query syntax can use "*" wildcard loop through entries in "results" array:

        var locations = jtoken.parse(googleresult)             .selecttokens("results[*].geometry.location")             .select(t => new { lat = (double)t["lat"], lng = (double)t["lng"] })             .tolist(); 

or, if prefer foreach loop:

        jobject obj = jobject.parse(googleresult);         jarray jarr = (jarray)obj["results"];         foreach (var item in jarr)         {             double lt = (double)item.selecttoken("geometry.location.lat");             double lg = (double)item.selecttoken("geometry.location.lng");         }
