.net – Inherit SortedDictionary – 这是一个很好的编程实践吗

因此,在我的代码中,我有一个自定义类,用于保存每个日期的每个餐馆的数据 – 例如：

Public Class DateData
    Public Property Var1 As Double = 0
    Public Property Var2 As Double = 0
    Public Property Var3 As Double = 0
    Public Property Var4 As Double = 0

    Public Sub Sub1()
      ....
    End Sub

   ... etc ....
End Class

因为我每个日期都得到这些数据(因为日期顺序对我的计算很重要),所以我也设置了以下类(大部分工作/计算完成)：

Public Class RestaurantData
    Inherits SortedDictionary(Of Date,DateData)

   Public Property Name As String
   Public Property RestaurantLevelData1 As Double = 0
   Public Property RestaurantLevelData2 As Double = 0

   Public Sub New(ByVal strName As String,ByVal DatesList As List(Of Date))
       _Name = strName
       For Each daDate As Date In DatesList
           Me.Add(daDate)
       Next
   End Sub

   Public Overloads Sub Add(ByVal daDate As Date)
        MyBase.Add(daDate,New DateData)
   End Sub

   Public Sub Sub1()
       For i As Integer = 0 To Me.Keys.Count - 1
           Dim daDate As Date = Me.Keys(i)
           Me(daDate).Sub1()
           .... etc ....
       Next
   End Sub

   ... etc ....
End Class

最后,由于这是针对大量的餐馆,我有一个类在餐厅级别上保存这个字典 – 例如：

Public Class RestaurantsDict
    Inherits Dictionary(Of String,RestaurantData)

   Public Overloads Sub Add(ByVal strName As String,ByVal Dates As List(Of Date))
       MyBase.Add(strName,New RestaurantData(strName,Dates))
   End Sub
End Class

好的,现在我已经设置了这个,我有两个主要问题：

>这是一个很好的设置方法吗？
我原来的代码包括几十个字典(Of String,SortedDictionary(Of Date,Double))
但我是一个相当新手的程序员,并且很想知道我是否想要实现更高效的架构.
>我当前设置它的方式非常难以调试 – 例如,我的RestaurantData的Count属性抛出System.TypeLoadException类型的异常.

总的来说,这个解决方案运行得非常好,但我想从中学到如何成为一个更好的.Net& OOP程序员.

谢谢！
