The File Object
File(文件)对象

The File object is used to return information about a specified file.
文件对象是用来返回指定文件的信息的。

To work with the properties and methods of the File object, you will have to create an instance of the File object through the FileSystemObject object. First; create a FileSystemObject object and then instantiate the File object through the GetFile method of the FileSystemObject object or through the Files property of the Folder object.
通过运用文件对象的属性和方法,首先,你必须通过FileSystemObject对象建立一个文件对象的实体;通过FileSystemObject对象的GetFile方法或通过文件对象的Files属性建立一个FileSystemObject对象以及列出一个文件的对象。

The following code uses the GetFile method of the FileSystemObject object to instantiate the File object and the DateCreated property to return the date when the specified file was created:
下面的代码通过使用FileSystemObject对象的GetFile用法列出了文件对象,通过使用DateCreated属性返回了指定文件被创立的时间。

<%
Dim fs,f
Set fs=Server.CreateObject("Scripting.FileSystemObject")
Set f=fs.GetFile("c:test.txt")
Response.Write("File created: " & f.DateCreated)
set f=nothing
set fs=nothing
%>

Output:

File created: 9/19/2001 10:01:19 AM
