Can't access Second Level of JSON String
-2
For a programming school project, I am making a weather app where I need to display the current temperature. In the JSON string the current temp is in the second level which I can't figure out how to access. In future I would also like to access the hourly and daily forecasts included in this string- if you have any ideas for how to do that. Any help would be appreciated. Here is my data:

Like the error says "currently" is not an array, it's an object. Arrays are denoted using square brackets whereas objects use curly braces {}.
Try this instead:
Dim currentlyObject As JObject = DirectCast(jsonObject("currently"), JObject)
'Example usage.
MessageBox.Show(currentlyObject("temperature"))
