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。
创建Dictionary对象

'定义并创建Dictionary对象，使用CreateObject创建并返回自动化对象的引用Dim DicSet Dic = CreateObject("Scripting.Dictionary") |
添加键值

Dim DicSet Dic = CreateObject("Scripting.Dictionary")'向Dictionary对象中添加键值对Dic.Add "Name", "Sirrah" 'Add方法第一个参数是Key值，第二个是Item值Dic.Add "Age", 23 |
删除键值

Dim DicSet Dic = CreateObject("Scripting.Dictionary")Dic.Add "Name", "Sirrah" '向Dictionary对象中添加键值对Dic.Add "Age", 23Dic.Item("Age") = 22 '修改键Age的值MsgBox Dic.Item("Age") '输出22 |
判断键是否存在

Dim DicSet Dic = CreateObject("Scripting.Dictionary")Dic.Add "Name", "Sirrah" '向Dictionary对象中添加键值对Dic.Add "Age", 23MsgBox Dic.Exists("Age") '判断键是否存在 |
输出所有键值
输出Dictionary对象所有键值，这边将介绍2种常用的循环方法，具体代码如下：

Dim Dic,DicsSet Dic = CreateObject("Scripting.Dictionary")Dic.Add "Name", "Sirrah" '向Dictionary对象中添加键值对Dic.Add "Age", 23Dics = dic.Items 'Items返回一个包含所有Item值的数组For i = 0 To dic.Count - 1 'Count返回Dictionary对象键数目 str = str & Dics(i) & vbCrlfNextMsgBox(str)Dim Dic,DicsSet Dics = CreateObject("Scripting.Dictionary")Dics.Add "Name", "Sirrah" '向Dictionary对象中添加键值对Dics.Add "Age", 23For Each Dic In Dics '循环遍历Dictionary键，并输出键值 MsgBox Dics.Item(Dic)Next |
补充一个实例
脚本文件：a.vbs，包含字典的添加、删除、判断键是否存在、修改键、修改值、遍历、统计键值对个数

调用方法：通过双击a.bat调用，a.bat代码如下：
cscript a.vbs
pause
