ASP File objekt

File-objektet bruges til at returnere information om den angivne fil.

Eksempel

Hvornår blev filen oprettet?
Dette eksempel viser, hvordan man først opretter et FileSystemObject-objekt og derefter bruger File-objektets DateCreated-egenskab til at få den dato og klokkeslæt, hvor den angivne fil blev oprettet.
Hvornår blev denne fil ændret?
Dette eksempel viser, hvordan man bruger DateLastModified-egenskaben til at få den dato og klokkeslæt, hvor den angivne fil blev ændret.
When was this file accessed?
This example demonstrates how to use the DateLastAccessed property to obtain the date and time when the specified file was last accessed.
Return the attributes of the specified file
This example demonstrates how to use Attributes to return the attributes of the specified file.

File object

The File object is used to return information about the specified file.

To operate on the properties and methods of the File object, we need to create an instance of the File object through the FileSystemObject. First, create a FileSystemObject object, and then create an instance of this File object through the GetFile method of the FileSystemObject object, or through the Files property of the Folder object.

The following code demonstrates how to use the GetFile method of the FileSystemObject object to create an instance of the File object and use the DateCreated property to return the date when the specified file was created:

<%
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: 8/8/2008 10:01:19 AM
