我试图在VBscript中创建一个简单的列表,但我找不到类似的东西。
基本上,我正在使用Active目录,我需要让用户所属的所有组成为域中所有用户的成员。现在,每个用户可能是不同数量的组的成员,因此我计划使用字典,其中密钥是用户的SAMID,值是他/她所属的所有组的列表。
我可以使用静态数组执行此操作,但是我必须为数组声明一个随机的大尺寸,这是不好的。我最喜欢做的是有一个类似python的列表,我可以简单地做一些像myList.Add这样的事情,不必担心调整大小。
我尝试使用System.Collection.ArrayList,但运行时遇到错误:
PS C:\tmp> cscript.exe .\foo.vbs
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.
C:\tmp\foo.vbs(1, 1) (null): 0x80131700
我该如何做到这一点?

摆脱字典并释放ArrayList的力量。
Option Explicit
dim list
Set list = CreateObject("System.Collections.ArrayList")
list.Add "Banana"
list.Add "Apple"
list.Add "Pear"
list.Sort
list.Reverse
wscript.echo list.Count ' --> 3
wscript.echo list.Item(0) ' --> Pear
wscript.echo list.IndexOf("Apple", 0) ' --> 2
wscript.echo join(list.ToArray(), ", ") ' --> Pear, Banana, Apple
编辑: 我看到你已经尝试过ArrayList,但是出现了错误。看来你的dotnet框架安装不正确(System.Collections.ArrayList是其中的一部分)。 Microsoft有一篇关于如何解决该问题的文章:http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/error-code-0x80131700/3add8d80-00e0-4355-a994-8630d01c18f5

Set dic = CreateObject("Scripting.Dictionary")
dic.Add "Item1", ""
dic.Add "Item2", ""
dic.Add "Item3", ""

这也是一个替代方案......我之前创建的实际List类。您可以自由使用/修改它以满足您的需求。我构建的原始类实际上依赖于另一个名为 ArrayIterator 的自定义类。
以下是如何使用它......
Set myList = New List
myList.Add("a")
myList.Add("b")
myList.Add("c")
' Iterate through the List using ArrayIterator. You can of course use other methods...
Set myListItr = myList.GetIterator
While myListItr.HasNext
MsgBox myListItr.GetNext
Wend
' Iterate through the List by getting the underlying Array.
Dim element
For Each element In myList.GetArray
MsgBox element
Next
列表类的源代码:
Class List
Private mArray
Private Sub Class_Initialize()
mArray = Empty
End Sub
' Appends the specified element to the end of this list.
Public Sub Add(element)
If IsEmpty(mArray) Then
ReDim mArray(0)
mArray(0) = element
Else
If mArray(UBound(mArray)) <> Empty Then
ReDim Preserve mArray(UBound(mArray)+1)
End If
mArray(UBound(mArray)) = element
End If
End Sub
' Removes the element at the specified position in this list.
Public Sub Remove(index)
ReDim newArray(0)
For Each atom In mArray
If atom <> mArray(index) Then
If newArray(UBound(newArray)) <> Empty Then
ReDim Preserve newArray(UBound(newArray)+1)
End If
newArray(UBound(newArray)) = atom
End If
Next
mArray = newArray
End Sub
' Returns the number of elements in this list.
Public Function Size
Size = UBound(mArray)+1
End Function
' Returns the element at the specified position in this list.
Public Function GetItem(index)
GetItem = mArray(index)
End Function
' Removes all of the elements from this list.
Public Sub Clear
mArray = Empty
End Sub
' Returns true if this list contains elements.
Public Function HasElements
HasElements = Not IsEmpty(mArray)
End Function
Public Function GetIterator
Set iterator = New ArrayIterator
iterator.SetArray = mArray
GetIterator = iterator
End Function
Public Function GetArray
GetArray = mArray
End Function
End Class
ArrayIterator 类的源代码:
Class ArrayIterator
Private mArray
Private mCursor
Private Sub Class_Initialize()
mCursor = 0
End Sub
Public Property Let SetArray(array)
mArray = array
End Property
Public Function HasNext
HasNext = (mCursor < UBound(mArray)+1)
End Function
Public Function GetNext
GetNext = mArray(mCursor)
mCursor = mCursor + 1
End Function
End Class
