示例1: Keys
Public ReadOnly Property Keys() As ICollection Implements IDictionary.Keys
Get
' Return an array where each item is a key.
' Note: Declaring keyArray() to have a size of ItemsInUse - 1
' ensures that the array is properly sized, in VB.NET
' declaring an array of size N creates an array with
' 0 through N elements, including N, as opposed to N - 1
' which is the default behavior in C# and C++.
Dim keyArray() As Object = New Object(ItemsInUse - 1) {}
Dim n As Integer
For n = 0 To ItemsInUse - 1
keyArray(n) = items(n).Key
Next n
Return keyArray
End Get
End Property
