示例1: Example
' 导入命名空间
Imports System.Collections.Generic
Module Example
Public Sub Main()
Dim numbers As New HashSet(Of Integer)()
For i As Integer = 0 To 19
numbers.Add(i)
Next i
' Display all the numbers in the hash table.
Console.Write("numbers contains {0} elements: ", numbers.Count)
DisplaySet(numbers)
' Remove all odd numbers.
numbers.RemoveWhere(AddressOf IsOdd)
Console.Write("numbers contains {0} elements: ", numbers.Count)
DisplaySet(numbers)
' Check if the hash table contains 0 and, if so, remove it.
If numbers.Contains(0) Then
numbers.Remove(0)
End If
Console.Write("numbers contains {0} elements: ", numbers.Count)
DisplaySet(numbers)
End Sub
Private Function IsOdd(ByVal i As Integer) As Boolean
Return ((i Mod 2) = 1)
End Function
Private Sub DisplaySet(ByVal coll As HashSet(Of Integer))
Console.Write("{")
For Each i As Integer In coll
Console.Write(" {0}", i)
Next
Console.WriteLine(" }")
End Sub
End Module输出：
numbers contains 20 elements: { 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 }
numbers contains 10 elements: { 0 2 4 6 8 10 12 14 16 18 }
numbers contains 9 elements: { 2 4 6 8 10 12 14 16 18 }
