for each sorted list

[vbgladiator]

Hey,

I have the following code in a class that inherits from SortedList.

Public Sub Dispose() Implements System.IDisposable.Dispose
        Dim entry As DictionaryEntry
        For Each entry In MyBase.Values
            CType(entry.Value, Invoice).Dispose()
        Next
    End Sub

The for each entry in mybase.value causes the following error
System.InvalidCastException - Specified cast is not valid.

Does anyone know why this is happening? I thought that Values return a dictionary entry.

Thanks,

Public Sub Dispose() Implements System.IDisposable.Dispose
        For Each Inv as Invoice In MyBase.Values
            Inv.Dispose()
        Next
End Sub

Thanks a lot. That worked fine.
I'm wondering though, how come the dictionary entry didn't work when the help file states that with teh for each loop you should use the dictionary entry.

i don't know, but possibly because when you inherit the sorted list and put your own objects in the collection, the collection consists of objects of type invoice, and not of type DictionaryEntry

The collection contains keys and values. But I was iterating through the Values collection which contained objects of type Invoice, so that's why I was getting that error.

Thanks a lot,
