I am trying to fetch all the latitude and longitude of my 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 all records:

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

For fetching one record it works fine but for all records its not working.
