Parameters

source: The compressed Stream.
destination: A directory path where decompressed files will be stored.

Exception	Description
ZipException	A critical zip operation error occurred during this activity. Please see ZipException.Message for details.

This method is a quick and easy way to use the Archive component to decompress a compressed Stream to a specified destination directory in one step. It combines the two operations of Archive.Open and Archive.Unzip.

The Archive.PreservePath property determines whether to preserve the paths. The Archive.Overwrite property determines whether and how an existing file will be overwritten. By default, the paths will not be preserved and the overwrite choice is Overwrite.Never. The Archive.Password property is used for decrypting the encrypted items.

If an error occurs for an individual item during this operation, the Archive.Exception Event will be raised.

The following example demonstrates using QuickUnzip with a stream destination.

Visual Basic

' Be sure to import the namespace by putting "Imports Dart.PowerTCP.Zip"
' at the top of your class.

' Preserve the path when unzipping
Archive1.PreservePath = True

' Overwrite any existing files
Archive1.Overwrite = Overwrite.Always

' Create a new stream with compressed data
Dim stream = New System.IO.FileStream("c:\test.zip", System.IO.FileMode.Open)

' Unzip the data in the stream to c:\test
Archive1.QuickUnzip(stream, "c:\Test")

C#

// Be sure to import the namespace by putting "using Dart.PowerTCP.Zip;"
// at the top of your class.

// Preserve the path when unzipping
archive1.PreservePath = true;

// Overwrite any existing files
archive1.Overwrite = Overwrite.Always;

// Create a new stream with compressed data
System.IO.FileStream stream = new System.IO.FileStream("c:\\test.zip", System.IO.FileMode.Open);

// unzip the data in the stream to c:\test
archive1.QuickUnzip(stream, "c:\\Test");
