VB.NET Json Path

I have created the following json :

{
  "emails": [
    {
      "someval": 0,
      "otherval": 2
    }
  ]
}

and I try to accessit like so :

priceObj.IntOf(".emails[0].otherval")
 priceObj.IntOf(".emails.otherval")

The output is 0 (invalid), tried my best to solve this but could not.

Can you please tell me how can I acces the value of "otherval" using path ? Thanks in advance.
