For each loop

[rmatthew]

I have the following strongly typed class...

 

I would like to use a for... each loop to iterate through collections.... Is that possible.

 

Public Class Tags

Inherits CollectionBase

 

Default Public Property item(ByVal index As Integer) As Tag

Get

Return CType(List.Item(index), Tag)

End Get

Set(ByVal value As Tag)

List.Item(index) = value

End Set

End Property

 

Public Function Add(ByVal item As Tag) As Integer

Return List.Add(item)

End Function

 

End Class

For an object to be enumerable (meaning you can use for each), you need to create an enumerator class that implements IEnumerator, and the enumerable class needs to implement the IEnumerable interface to return the enumerator. That probably sounds like a headache, but I believe that the CollectionBase has already implemented the IEnumerable interface. Have you tried using your Tags class in a For Each loop?

Back and forth

 

Yes, did try -

I have a class that does one but not the other

 

I had one that used the inumerable and would indeed work in a for each loop, but it was based on a position variable and an array of objects....

 

Now that I have the strongly typed class, I end up with no array/position and am not familiar enough with the list that I get to implement the other.
