Retrieve data from JSON
Retrieve data from JSON
(OP)
I am trying to receive data from a json feed.
I can successfully perform the http request which gives me some json data like below:
jsonObject = {{
"data": [
{
"latitude": -20.025382,
"longitude": 143.314035,
"type": "address",
"name": "xxxx",
"number": "xxx",
"postal_code": "42111",
"street": "xxxx",
"confidence": 1,
...
But when I try to retrieve the latitude, it retrieves nothing.
Here is my code to perform the request and try to read the data:
Where am I going wrong?
Thanks

Private Sub GetCoordinates()

Dim request As HttpWebRequest
Dim WebResponse As HttpWebResponse = Nothing
Dim reader As StreamReader
request = DirectCast(WebRequest.Create(url), HttpWebRequest)
WebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
reader = New StreamReader(WebResponse.GetResponseStream())
Dim RawResponse = reader.ReadToEnd()
Dim json As String = RawResponse
Dim jsonObject As Newtonsoft.Json.Linq.JObject = Newtonsoft.Json.Linq.JObject.Parse(json)
Session("Latitude") = CStr(jsonObject("latitude"))
'Session("Latitude") = jsonObject.SelectToken("data.latitude")
End Sub Where am I going wrong?
