VBS基础篇 - Dictionary对象

Dictionary是存储数据键和项目对的对象，其主要属性有Count、Item、Key，主要方法有Add、Exists、Items、Keys、Remove、RemoveAll。

‘建立字典
Dim Dict : Set Dict = CreateObject("Scripting.Dictionary")

‘添加键值对
Dict.Add "Key1", "Item1"
Dict.Add "Key2", "Item2"
Dict.Add "Key3", "Item3"

‘字典中键值对数量
WScript.Echo "字典中现有键值对数量: " & Dict.Count ‘让一个脚本在屏幕上显示文本信息

WScript.Echo 

‘检查指定键是否存在
If Dict.Exists("Key1") Then
    WScript.Echo "Key1 存在!"
Else
    WScript.Echo "Key1 不存在!"
End If

If Dict.Exists("Keyn") Then
    WScript.Echo "Keyn 存在!"
Else
    WScript.Echo "Keyn 不存在!"
End If

WScript.Echo 

‘遍历字典
Sub TraverseDict
    Dim DictKeys, DictItems, Counter
    DictKeys = Dict.Keys
    DictItems = Dict.Items ‘Items返回一个包含所有Item值的数组
    For Counter = 0 To Dict.Count - 1 ‘Count返回Dictionary对象键数目
        WScript.Echo _
            "键: " & DictKeys(Counter) & _ ‘& 字符串连接运算符
            "值: " & DictItems(Counter)
    Next
End Sub

TraverseDict

WScript.Echo 

‘在一个键值对中，修改键或修改值
Dict.Key("Key2") = "Keyx"
Dict.Item("Key1") = "Itemx"
TraverseDict

WScript.Echo 

‘删除指定键
Dict.Remove("Key3")
TraverseDict

WScript.Echo 

‘删除全部键
Dict.RemoveAll
WScript.Echo "字典中现有键值对数量: " & Dict.Count
