嵌套字典在VB .NET

Question

我想創建一個嵌套的通用字典，但分配內存時我正在運行時錯誤，我應該怎麼分配內存 我已經聲明瞭一個通用字典如下

dim tmp as generic.dictionary(of object,generic.dictionary (of int, object)) 

我用下面的語句來分配內存

dim tmp as generic.dictionary (of object,generic.dictionary (of int, object)) = New generic.dictionary (of object,generic.dictionary (of int, object)) 

問候， 維沙爾

下面的代碼compil es並且執行沒有問題。

Option Strict On 
Option Explicit On 

Module Module1 
    Public Sub Main() 
     Dim tmp As Generic.Dictionary(Of Object, Generic.Dictionary(Of Integer, Object)) 
     tmp = New Generic.Dictionary(Of Object, Generic.Dictionary(Of Integer, Object)) 
    End Sub 
End Module
