Я пытаюсь разобрать это, это мой код:

Dim StoreWrapper = JsonConvert.DeserializeObject(Of StoreWrapper)(html) 
Dim AllStores = StoreWrapper.Stores 
Results.Text = AllStores(1).StoreID.ToString 

Public Class StoreWrapper 
    Public Property Store As List(Of Store) 
End Class 
Public Class Store 
Public Property StoreID As String 
Public Property IsDeliveryStore As Boolean 
Public Property MinDistance As Double 
Public Property MaxDistance As Double 
Public Property Phone As String 
Public Property AddressDescription As String 
Public Property HolidaysDescription As String 
Public Property HoursDescription As String 
'Public Property ServiceHoursDescription As String 
Public Property IsOnlineCapable As Boolean 
Public Property IsOnlineNow As Boolean 
Public Property IsNEONow As Boolean 
Public Property IsSpanish As Boolean 
Public Property LocationInfo As String 
'Public Property LanguageLocationInfo As String 
Public Property AllowDeliveryOrders As Boolean 
Public Property AllowCarryoutOrders As Boolean 
Public Property IsOpen As Boolean 
'Public Property ServiceIsOpen As String 
End Class

Ошибки я получаю:

необработанное исключение типа «System.NullReferenceException» произошло в LocationFinder.exe

Дополнительная информация rmation: Ссылка на объект не установлена в экземпляр объекта.

Пожалуйста, прочитайте [ask] и возьмите [тур], нам нужно знать, в какой строке это происходит. Также найдите время, чтобы узнать, как отформатировать код, чтобы он выглядел как код. – Plutonix

Ваш класс не совсем корректен. Не evenrything является строкой, есть некоторые логические переменные ('true' является bool,' 'true '' будет строкой) и удваивается; это также похоже на то, что вам не хватает некоторых типов: 'ServiceHoursDescription',' LanguageLocationInfo' и 'ServiceIsOpen' являются их собственными типами – Plutonix

Возможный дубликат [Что такое исключение NullReferenceException и как его исправить?] (http: // stackoverflow. com/questions/4660142/what-is-a-nullreferenceexception-and-how-do-i-fix-it) –

Необходимое изменение было Public Property Store As List(Of Store)

Спасибо!
