It really depends on what it is that you want to do but for plain old look at all the content either of For Next loop or For Each works as well as any other method.

Don't use ArrayList and HashTable. They are outdated. Use List and Dictionary instead:

VB.NET

Dim x As New List(Of String) From {"a", "b"}
Dim y As New Dictionary(Of String, Integer) From {{"C", 3}, {"D", 8}}
For Each item As String In x
	MessageBox.Show(item)
Next
For Each key As String In y.Keys
	MessageBox.Show(key + ", " + y(key).ToString())
Next

There are many ways to "navigate" those collection types, but that's one way.
