我对一些小概念感到困惑 [英] i am confused in a small concepts

问题描述

我对 VBscript 非常陌生，并且正在努力学习所有概念.在我的练习中，我一直在怀疑.

I am very new to VBscript and learning hard all the concepts. During my practice I am stuck with a doubt.

dim a,b,c
set a = CreateObject("scripting.filesystemobject") 'initiate the file system object'
set b = a.GetFolder("E:\test") 'returns a object . and for the instance that varaiable b refers to that returned object'
c = b.datecreated 'accesing and storing the property to a variable /C/'
msgbox "folder: " &c

当我执行此操作时，没有错误消息并且工作正常.但是当我改变

When I execute this there is no error message and it works fine. But when I change

c = b.datecreated TO set c = b.datecreated 比

它显示此错误:

> object required:'datecreated'

我知道这是一件基本的事情，但有时小事情会让你学到很多东西，对未来有帮助.

I know it's a basic thing but some time small things make you learn a lot and helpful for future.

推荐答案

关键字 Set 在 VBScript 中仅用于对象分配:

The keyword Set is used in VBScript only for assignment of objects:

set a = CreateObject("scripting.filesystemobject")

非对象 - 如创建日期 - 在没有 Set 的情况下分配.

Non-objects - like the creation date - are assigned without Set.

c = b.datecreated

(这是我最喜欢的 VBScript 的坏处.)

(This is my favorite nastiness of VBScript.)
