这次课程我们主要来讲解DICTIONARY对象的使用，讲解此对象的目的是为了后续在讲解《测试对象字典的应用》以及《面向对象的代码设计模式》做铺垫。因此虽然本次课程内容相对较为简单，但是DICTIONARY这个知识点是非常重要的，在后续的课程内容中我们会经常用到，因此希望大家在看完之后能够多多实践，掌握好它为后续课程打好扎实的基础。

• Dictionary ---- 字典对象

说明：一个能够增删改的容器，同时也是一个COM组件

• 添加项

Set dic=CreateObject("Scripting.Dictionary")
dic.Add "a","test was a"
dic.Add "b","test was b"
dic.Add "c","test was c"
MsgBox dic.Item("a") 'item可省略

• 删除项

Set dic=CreateObject("Scripting.Dictionary")
dic.Add "a","test was a"
dic.Add "b","test was b"
dic.Add "c","test was c"
MsgBox dic.Count '3个
dic.Remove("a")
MsgBox dic.Count '2个
Msgbox dic("a") '已空

• 修改项

Set dic=CreateObject("Scripting.Dictionary")
dic.Add "a","test was a"
dic.Add "b","test was b"
dic.Add "c","test was c"

MsgBox dic("a") '修改之前
dic.Item("a")="zzxxbb112"
MsgBox dic("a") '修改之后
