VB.NET - Extract Pairs out of a string (JSON)

I use VB.Net and want to extract The Keypair values and put them into a class with the same variable (names) and values.

When I do a API call the outcome is shown as below.
How can I extract the KeyPair values? Like "Username":  "<text>"?

{
"License":
{
"LicenseKey": "Known",
"LicenseId": "****",
"Username": "++",
"Password": "*",
"ProductCode": "*",
"ProductName": "",
"Quantity": 1,
"PurchaseType": "Renew",
"CreatedDate": "28-07-2015",
"ExpirationDate": "27-07-2017",
"CustomerName": "*",
"CustomerCompany": "",
"CustomerEmail": "a@b.com",
"DiscountCode": 0,
"Status": "Active",
"BundleProductCode": "0",
"BundleProductName": "Advanced",
"BundleQuantity": 0,
"ELAPassword": "",
"CountryId": 60
},
"Result": true,
"Messages": []
}

you can create your custom class and then deserialize to get the values you want.

you can look for samples at Json.NET to do this

Import Newtonsoft.Json and try

Dim list As List(Of String) = Newtonsoft.Json.JsonConvert.DeserializeObject(Of List(Of String))(strJSON)

For Each item As String In list
	Console.WriteLine(item)
Next

In other words:
Module Module1
	Dim data = "{""License"":{""LicenseKey"": ""Known"", ""LicenseId"": ""****"", ""Username"": ""++"", ""Password"": ""*"", ""ProductCode"": ""*"", ""ProductName"": """", ""Quantity"": 1, ""PurchaseType"": ""Renew"", ""CreatedDate"": ""28-07-2015"", ""ExpirationDate"": ""27-07-2017"", ""CustomerName"": ""*"", ""CustomerCompany"": """", ""CustomerEmail"": ""a@b.com"", ""DiscountCode"": 0, ""Status"": ""Active"", ""BundleProductCode"": ""0"", ""BundleProductName"": ""Advanced"", ""BundleQuantity"": 0, ""ELAPassword"": """", ""CountryId"": 60 }, ""Result"": true, ""Messages"": [] }"

	Sub Main()
		Dim [response] = Newtonsoft.Json.JsonConvert.DeserializeObject(Of Response)(data)
		Console.WriteLine("UserName: {0}", [response].License.Username)
		Console.ReadLine()
	End Sub
End Module

Class Response
	Public Property [License]() As License
	Public Property Result() As Boolean
	Public Property Messages() As List(Of String)
End Class

Class License
	Public Property LicenseKey() As String
	Public Property LicenseID() As String
	Public Property Username() As String
	Public Property Password() As String
	Public Property ProductCode() As String
	Public Property ProductName() As String
	Public Property Quantity() As Integer
	Public Property PurchaseType() As String
	Public Property CreatedDate() As String
	Public Property ExpirationDate() As String
	Public Property CustomerName() As String
	Public Property CustomerCompany() As String
	Public Property CustomerEmail() As String
	Public Property DiscountCode() As Integer
	Public Property Status() As String
	Public Property BundleProductCode() As String
	Public Property BundleProductName() As String
	Public Property BundleQuantity() As Integer
	Public Property ELAPassword() As String
	Public Property CountryId() As Integer
End Class

Open in new window

Produces the following output -Capture.JPG-saige-
