Read a web page in a variable in VB

To serialize a Json in Vb.Net DataContractAttribute . / p>

First you would have to create an object to receive this JSON, realize that your example pussui objects inside the Json itself, example:

"atividades_secundarias": [
    {
      "text": "Reprodução de vídeo em qualquer suporte",
      "code": "18.30-0-02"
    },

1. You will create a method that will receive this JSON and do deserialization

' VB.NET
Private Function DeserializarDataContractJsonSerializer() As List(Of SeuObjeto)
    Using Stream = New System.IO.FileStream(JsonQueVocêPassa, System.IO.FileMode.Open)
        Dim Serializer = New System.Runtime.Serialization.Json.DataContractJsonSerializer(GetType(List(Of Pedido)))
        Return DirectCast(Serializer.ReadObject(Stream), List(Of SeuObjeto))
    End Using
End Function

JsonQueVocêPassa = link

SeuObjeto = Object that you create with the Json framework you are trying to serialize.

In this example you are reading a Json from a file using the and mounting the object.
