ASP-Dictionary对象-基础用法

1、存在
dim d

set d=Server.CreateObject("Scripting.Dictionary")

d.Add "c", "China"

d.Add "i", "Italy"

if d.Exists("c")= true then

    Response.Write("键存在。")

else

    Response.Write("键不存在。")

end if

set d=nothing

2、遍历值

a=d.Items

for i = 0 To d.Count -1

    s = s & a(i) & "<br />"

next

Response.Write(s)

3、遍历主键

a=d.Keys

for i = 0 To d.Count -1

    s = s & a(i) & "<br />"

next

Response.Write(s)

4、返回值

d.Add "c", "China"

d.Add "i", "Italy"

Response.Write("项目 i 的值是：" & d.item("i"))

5、修改主键

d.Add "c", "China"

d.Add "i", "Italy"

d.Key("i") = "it"

Response.Write("键 i 已设置为 it，其值是：" & d.Item("it"))

6、返回数量
d.Count

7、删除
DictionaryObject.Remove(key)
DictionaryObject.RemoveAll
