vb .net access json information

问题

I have the following json output:

{
   "id":"354asda-asd435544-35438738fd",
   "oid":"354asda-asd435544-35438738fd-asdasd1212",
   "mids":[
      476252
   ],
   "name":"This is my name",
   "language":"en",
   "released":"2020-01-24",
   "url":"https://myownurl",
   "url2":"https://myownurl2",
   "image":true,
   "image_url":{
      "small":"https://myownurl/img_sm.jpg",
      "large":"https://myownurl/img_lg.jpg",
      "png":"https://myownurl/img_sm.png",
   },
...
}

I'm trying to access this information, but getting some trouble with it, with the image_url property.

Dim selected As String = ListBox1.SelectedItem()
Dim splited() As String = selected.Split(" - ")

Dim card As String = ListBox2.SelectedItem()
Dim cardsplit() As String = card.Split(" - ")

Dim uriString As String = "https://myownapi/" & splited(0) & "/" & cardsplit(0)

Dim Request As HttpWebRequest = WebRequest.Create(New Uri(uriString))
Dim JSON_Response As String = New StreamReader(Request.GetResponse().GetResponseStream()).ReadToEnd()

Dim JSON_Obj1 As Object = New JavaScriptSerializer().DeserializeObject(JSON_Response)
TextBox2.Text = JSON_Response.ToString
Dim Test1 As String = JSON_Obj1("image_url")
TextBox1.Text = Test1("large")

How can I properly access all this information, including information inside those brackets [ ] and { }? Thanks.
