Listing the contents of a zip file

This topic demonstrates how to get a listing of all of the files contained in a zip file.

Basic steps

To list the contents of a zip file, the following steps must be performed:

Retrieve a reference to a zip file using the ZipArchive class.
Call the GetFiles method to retrieve a listing of the files contained within the zip file.
You can now loop through the files and extract the desired information.

This example demonstrates how to list the contents of a zip file.

VB.NET Copy Code

VB.NET	Copy Code
`Imports Xceed.Zip Imports Xceed.FileSystem` `Dim zip As New ZipArchive(New DiskFile("c:\test.zip")) Dim f As AbstractFile` `For Each f In zip.GetFiles( True ) ListBox1.Items.Add( f.FullName ) Next`

Imports Xceed.Zip Imports Xceed.FileSystem

Dim zip As New ZipArchive(New DiskFile("c:\test.zip")) Dim f As AbstractFile

For Each f In zip.GetFiles( True ) ListBox1.Items.Add( f.FullName ) Next

C#	Copy Code
`using Xceed.Zip; using Xceed.FileSystem; ZipArchive zip = new ZipArchive( new DiskFile( @"c:\test.zip" ) ); foreach( AbstractFile f in zip.GetFiles( true ) ) { Console.WriteLine( f.FullName ); }`

The main questions you should ask yourself when listing the contents of a zip file are:

Do you want to filter (specify specific files and folders) the items that are to be listed? Use filters.
Do you also want to retrieve a listing of the zipped folders? Use the GetFolders method.
Do you want to retrieve a reference to a single zipped file or folder? Use the GetFile or GetFolder methods.
Do you want to display the status of the operation? See the Events topic.
Do you want to list the contents of a specific folder within the zip file? Create an instance of a ZippedFolder object rather than a ZipArchive object.
Do you want to filter your list of items? See the Filters topic.
Do you only want to do basic zip file operations? Use the QuickZip class.
