[英]Create Zip files in Classic ASP using DotNetZip or SharpZipLib
In ASP.Net two of the possible ways to make the zip files are 在ASP.Net中,制作zip文件的两种可能方法是
How can i use any of these in Classic ASP to make the zip files ? 如何在Classic ASP中使用其中任何一个来制作zip文件? And which one will be better ?
哪个会更好?
You can't use any of those libraries in classic asp. 您不能在经典ASP中使用任何这些库。 One way would be to try to register them as COM components using the regasm.exe utility, although I am not sure whether those assemblies are marked with the COMVisible attribute.
一种方法是尝试使用regasm.exe实用程序将它们注册为COM组件,尽管我不确定这些程序集是否用COMVisible属性标记。
You will need to create a COM wrapper for the .NET library of choice. 您将需要为所选的.NET库创建COM包装器 。
You will then be able to reference the wrapper in classic ASP and use it. 然后,您将能够在经典ASP中引用包装器并使用它。
Contrary to some perception, it's easy to use DotNetZip from COM environments, including ASP. 与某些看法相反,从COM环境(包括ASP)使用DotNetZip很容易。
DotNetZip includes examples that show creating zip files from VBScript and Javascript. DotNetZip包括显示从VBScript和Javascript创建zip文件的示例。 You can easily adapt this code to use it from ASP classic.
您可以轻松地修改此代码以在ASP classic中使用它。
There is also an example in the source code for reading a ZIP file from within an ASP classic page. 源代码中还有一个示例,用于从ASP经典页面中读取ZIP文件。 It looks like this:

' ASP DotNetZip Example
' -------------------------------------------------------
' This example ASP page uses DotNetZip (Ionic.Zip.dll) via COM
' interop. The page opens a zip file, then allows the user
' to download any individual file within the zip file.
'
'' To get this to work, you must be sure to register DotNetZip for COM
'' interop (regasm). Also you need to be sure that IIS/ASP has the correct
'' permissions to instantiate the ZipFile object. In my experience I Was
'' able to do this by copying Ionic.Zip.dll to the
'' c:\windows\system32\inetsrv directory, then calling "regasm /codebbase
'' Ionic.Zip.dll" from within that directory.
'' This example assumes that the ASP page is deployed into a directory,
'' that contains a subdirectory called "fodder". Fodder must be readable,
'' and should contain one or more zip files. This page allows the user to
'' select a zip file, then select a file within the zip file, and download
'' that file.
''
If Request.Form("Submit") = "Download" Then
dim pathForZipFile, fileToDownload
pathForZipFile= Request.Form("zipFile")
if pathForZipFile <> "" Then
fileToDownload = Request.Form("fileToDownload")
Response.Clear
Response.AddHeader "Content-Disposition", "attachment; filename=" & fileToDownload
Response.ContentType = "application/octet-stream"
pathForZipFile = Server.MapPath("fodder\" & pathForZipFile)
dim zip, ms
set zip = Server.CreateObject("Ionic.Zip.ZipFile")
zip.Initialize(pathForZipFile)
set ms = Server.CreateObject("System.IO.MemoryStream")
dim selectedEntry, entry
For Each entry in zip
If entry.FileName = fileToDownload Then
set selectedEntry = entry
End If
Next
selectedEntry.Extract_3(ms)
zip.Dispose
dim fred
fred = ms.ToArray
Response.BinaryWrite(fred)
ms.Dispose
