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)
next
Response.Write(s)

3、遍历主键

a=d.Keys
for i = 0 To d.Count -1
s = s & a(i)
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

    An interesting discussion is worth comment. I
    do think that you need to publish more about this subject, it might not be a taboo matter but generally people don’t talk about
    such subjects. To the next! Best wishes!!

    Hello, i read your blog occasionally and i own a similar one and i was just
    wondering if you get a lot of spam feedback? If so how do you protect against it, any plugin or anything you can recommend?
    I get so much lately it’s driving me crazy so any
    help is very much appreciated.
