StringCollection Class

Represents a collection of strings.
StringCollection accepts Nothing as a valid value and allows duplicate elements.
String comparisons are case-sensitive.
Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.

Syntax:

  Dim sColl As New StringCollection()
  Dim colArr() As String = {"RED", "GREEN", "YELLOW", "BLUE"}
      sColl.AddRange(colArr)

ListDictionary Class

Implements IDictionary using a singly linked list.
Recommended for collections that typically contain 10 items or less.
It is smaller and faster than a Hashtable
This should not be used if performance is important for large numbers of elements.

Members, such as Item, Add, Remove, and Contains are O(n) operations, where n is Count.

Syntax:

For Each direntry As DictionaryEntry In myListDictionary
  ...
Next direntry
