Solved: JSON response syntax | Experts Exchange

Your JSON object translates loosely to this:

Class JsonData
	Public Property Status() As String
	Public Property [Product]() As Product
End Class

Class Product
	Public Property Name() As String
	Public Property Code() As String
	Public Property Price() As String
	Public Property Active() As Boolean
	Public Property [Contact]() As Contact
End Class

Class Contact
	Public Property Name() As String
	Public Property Phone() As String
	Public Property Email() As String
End Class

Open in new window

Example -

Imports Newtonsoft.Json
Imports System.Reflection
Imports System.Runtime.CompilerServices

Module Module1
	Const json = "{""status"": ""OK"",""product"":{""name"": ""ABC"",""code"": ""A"",""Price"": ""2.5"",""active"": true,""contact"":{""name"": ""X"",""phone"": ""999-999-9999"",""email"": ""X@company.com""}}}"
	Sub Main()
		Dim response = JsonConvert.DeserializeObject(Of JsonData)(json)
		Console.WriteLine(response.ToString())
		Console.ReadLine()
	End Sub
End Module

Class JsonData
	Public Property Status() As String
	Public Property [Product]() As Product

	Public Overrides Function ToString() As String
		Return Me.GetPropertiesString()
	End Function
End Class

Class Product
	Public Property Name() As String
	Public Property Code() As String
	Public Property Price() As String
	Public Property Active() As Boolean
	Public Property [Contact]() As Contact

	Public Overrides Function ToString() As String
		Return Me.GetPropertiesString()
	End Function
End Class

Class Contact
	Public Property Name() As String
	Public Property Phone() As String
	Public Property Email() As String

	Public Overrides Function ToString() As String
		Return Me.GetPropertiesString()
	End Function
End Class

Module Extensions
	<Extension()> _
	Public Function GetPropertiesString(Of T)(source As T) As String
		Dim result = String.Empty
		If source IsNot Nothing Then
			result = String.Join("; ", (From [property] As PropertyInfo In GetType(T).GetProperties() Select String.Format("{{ {0}, {1} }}", [property].Name, [property].GetValue(source, Nothing))))
		End If
		Return result
	End Function
End Module

In the future, you can use http://json2csharp.com/ in order to generate c# classes. Translating these classes into VB.NET is relatively straigthforward; e.g. the classes from your presented json are generated as:

public class Contact
{
    public string name { get; set; }
    public string phone { get; set; }
    public string email { get; set; }
}

public class Product
{
    public string name { get; set; }
    public string code { get; set; }
    public string Price { get; set; }
    public bool active { get; set; }
    public Contact contact { get; set; }
}

public class RootObject
{
    public string status { get; set; }
    public Product product { get; set; }
}
