示例1: PeopleEnum
' When you implement IEnumerable, you must also implement IEnumerator.
Public Class PeopleEnum
Implements IEnumerator
Public _people() As Person
' Enumerators are positioned before the first element
' until the first MoveNext() call.
Dim position As Integer = -1
Public Sub New(ByVal list() As Person)
_people = list
End Sub
Public Function MoveNext() As Boolean Implements IEnumerator.MoveNext
position = position + 1
Return (position < _people.Length)
End Function
Public Sub Reset() Implements IEnumerator.Reset
position = -1
End Sub
Public ReadOnly Property Current() As Object Implements IEnumerator.Current
