解碼複雜的JSON數組vb.net

我已經有一個問題很多麻煩了幾天，現在我對此感到非常沮喪！我想知道如何解碼VB.NET 4.5框架中的JSON數組。我試圖使用反序列化/序列化類。這裏是數組：解碼複雜的JSON數組vb.net

{ 「LaunchIDs」：[ 「2」，「3」，「4」，「5」，「6」，「7」，「8」，「9」，「10」]，「FavoriteID」：NULL，「用戶名」：「測試」，「錯誤」：0，「消息」：「您已經成功登錄」}

用於陣列中的代碼是

Public Class JSONCode 
    Public LaunchIDs As Integer 
    Public FavoriteIDAs Integer 
    Public username As String 
    Public [error] As Integer 
    Public message As Integer 
End Class

這是我在應用程序內部如何使用它。

Dim client As New WebClient() 
Dim jsonResponse As String = "{""LaunchIDs"":[""2"",""3"",""4"",""5"",""6"",""7"",""8"",""9"",""10""],""FavoriteID"":null,""username"":""Test"",""error"":0,""message"":""You have successfully logged in""}") 
Dim serializer As New JavaScriptSerializer() 
Dim response As JSONCode = serializer.Deserialize(Of JSONCode)(jsonResponse) 
     code = response.error 
     If code = 0 & response.message = "You have successfully logged in" Then 
      LoginFunction = True 
      botids = response.botids 
      ListBox1.AddItem(botids) 
     Else 
      Alert(Style.Critical, response.message) 
     End If 
End If

該數組將從Web地址檢索（我解決了這個問題後），所以它現在有點亂。 Alert（）只是一個小小的自定義msgBox函數。

當我嘗試和調試時出現此錯誤。類型'System.Int32'不支持數組的反序列化。

您的類的聲明是錯誤的，應該是

Public Class JSONCode_cor 
    Public LaunchIDs As Integer() 
    Public FavoriteID As Integer() 
    Public username As String 
    Public [error] As Integer 
    Public message As String 
End Class

這我在代碼中使用：

Dim jsonResponse As String = "{""LaunchIDs"":[""2"",""3"",""4"",""5"",""6"",""7"",""8"",""9"",""10""],""FavoriteID"":null,""username"":""Test"",""error"":0,""message"":""You have successfully logged in""}" 
Dim serializer As New Web.Script.Serialization.JavaScriptSerializer() 
Dim response As Object = serializer.Deserialize(Of JSONCode_cor)(jsonResponse)

和它的作品。你的問題是你聲明LaunchID爲Integer，但實際上它是一個數組Integer()

frmMain.FlatListBox2.AddItem（LaunchIDs）給出了「int32」或其他值，所以我試着用AddRange切換AddItem。現在我得到錯誤1由於'整數'不是參考類型，因此'1維數組整數'類型的值無法轉換爲'1維數組對象'。 – user2827489

@ user2827489查看更新後的答案。 – IvanH

這就是我已經使用的代碼。那麼我想出了這個問題，必須做一個函數來將整數轉換爲一個字符串數組。 – user2827489
