我可以在VBA集合中遍历键/值对吗？ [英] Can I loop through key/value pairs in a VBA collection?

问题描述

在VB.NET中，我可以遍历字典的键/值对：

In VB.NET, I can iterate through a dictionary's key/value pairs:

Dictionary<string, string> collection = new Dictionary<string, string>();
collection.Add("key1", "value1");
collection.Add("key2", "value2");

foreach (string key in collection.Keys)
{
    MessageBox.Show("Key: " + key + ".  Value: " + collection[key]);
}

我知道在VBA中我可以遍历值集合对象：

I know in VBA I can iterate through the values of a Collection object:

Dim Col As Collection
Set Col = New Collection
Dim i As Integer
Col.Add "value1", "key1"
Col.Add "value2", "key2"

For i = 1 To Col.Count
    MsgBox (Col.Item(i))
Next I

我也知道我这样做

推荐答案

，您无法从集合中检索键的名称。相反，您需要使用字典对象：

you cannot retrieve the name of the key from a collection. Instead, you'd need to use a Dictionary Object:

Sub LoopKeys()
    Dim key As Variant

    'Early binding: add reference to MS Scripting Runtime
    Dim dic As Scripting.Dictionary
    Set dic = New Scripting.Dictionary

    'Use this for late binding instead:
    'Dim dic As Object
    'Set dic = CreateObject("Scripting.Dictionary")

    dic.Add "Key1", "Value1"
    dic.Add "Key2", "Value2"

    For Each key In dic.Keys
        Debug.Print "Key: " & key & " Value: " & dic(key)
    Next
End Sub
