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

An unzip operation on an ArchiveItem will only decompress the item and not any other items in the collection.

The following example demonstrates unzipping from an individual ArchiveItem.

Visual Basic

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

' Open a compressed stream.  This populates the Archive collection.
Archive1.Open("c:\test.zip")

If (Archive1.Count > 1) Then

    ' Unzip the first item in the collection to a file, preserving its path
    Archive1(0).Unzip("c:\Test", True, Overwrite.Always)

    ' Unzip the second item in the collection to a memory stream
    Dim stream = New System.IO.MemoryStream()
    Archive1(1).Unzip(stream)
End If

C#

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

// Open a compressed stream.  This populates the Archive collection.
archive1.Open("c:\\test.zip");

if (archive1.Count > 1)
{
	// Unzip the first item in the collection to a file, preserving its path
	archive1[0].Unzip("c:\\Test", true, Overwrite.Always);

	// Unzip the second item in the collection to a memory stream
	System.IO.MemoryStream stream = new System.IO.MemoryStream();
	archive1[1].Unzip(stream);
}
