The second parameter, keyOrIndexOrPath, specifies the portion of the JSON data to operate on: key – the name of a key in a JSON object; index – the index of an element in a JSON array (the first element has an index of 0) path – a hierarchical string of key names, array indexes, or both Then I used Json.NET using JArray it parses the data and used JToken but could not get.
