你看过字典对象吗？

它作为 Microsoft Scripting Runtime 的一部分提供。 this SO answer 给出了如何添加它的清晰示例。 .

Sub DictExample1()

Dim dict As Dictionary
Dim v As Variant

    'Create the dictionary          
    Set dict = New Dictionary

   'Add some (key, value) pairs
    dict.Add "John", 34
    dict.Add "Jane", 42
    dict.Add "Ted", 402

    'How many items do we have?
    Debug.Print "Number of items stored: " & dict.Count

    'We can retrieve an item based on the key
    Debug.Print "Ted is " & dict.Item("Ted") & " years old"


   'We can test whether an item exists
    Debug.Print "We have Jane's age: " & dict.Exists("Jane")
    Debug.Print "We have Zak's age " & dict.Exists("Zak")

    'We can update a value by replacing it
   dict.Item("Ted") = dict.Item("Ted") / 10

    Debug.Print "Ted's real age is: " & dict.Item("Ted")

   'We can add more items
    dict.Add "Carla", 23

   'And we can iterate through the complete dictionary
    For Each v In dict.Keys
        Debug.Print "Name: " & v & "Age: "; dict.Item(v)
    Next

End Sub
