Xceed Zip for .NET gives you the possibility to decompress compressed byte arrays. For more information, you can refer to the Decompressing a byte array and Decompressing stream data topics.
QuickCompression Example
The following example demonstrates how to decompress an array of bytes using the static Decompress method of the QuickCompression class.
| VB.NET |
 Copy Code |
|
Imports Xceed.Compression
Dim decompressedData() As Byte = QuickCompression.Decompress( compressedData )
' Display the decompressed data
MessageBox.Show( System.Text.Encoding.Default.GetString( decompressedData ) )
|
| C# |
Copy Code |
|
using Xceed.Compression;
byte[] decompressedData = QuickCompression.Decompress( compressedData );
// Display the decompressed data
MessageBox.Show( System.Text.Encoding.Default.GetString( decompressedData );
|
FileSystem Example
The following example demonstrates how to decompress an array of bytes using the FileSystem object model.
| VB.NET |
Copy Code |
|
Imports System.IO
Imports Xceed.Compression
' If you do not want the inner stream to be closed by the CompressedStream
' then set the CompressedStream's Transient property to true.
'
' The compressed data was compressed using the Compress example
Dim sourceStream = New MemoryStream(compressedData)
Dim compStream As New CompressedStream(sourceStream)
Dim destinationStream As New MemoryStream()
' 32K at at time.
Dim buffer(32768) As Byte
Dim bytesRead As Integer = 0
' Loop until we have nothing more to read from the source stream
Do
bytesRead = compStream.Read(buffer, 0, buffer.Length)
If bytesRead > 0 Then
destinationStream.Write(buffer, 0, bytesRead)
End If
Loop Until bytesRead = 0
' Close the destination stream and the CompressedStream.
'
' Because the CompressedStream will automatically close the source
' memory stream, there is no need to call Close once we are done with the stream.
destinationStream.Close()
compStream.Close()
' To get access to the MemoryStream's decompressed data, you can use:
byte[] decompressedData = destinationStream.ToArray();
' ToArray() works even when the memory stream is closed.
|
| C# |
Copy Code |
using System.IO;
using System.Compression;
// Because the CompressedStream will automatically close the source
// memory stream, there is no need to declare the memory stream within a using
// statement or to call Close once we are done with the stream.
//
// If you do not want the inner stream to be closed by the CompressedStream
// then set the CompressedStream's Transient property to true.
//
// The compressed data was compressed using the Compress example
MemoryStream sourceStream = new MemoryStream( compressedData );
using( CompressedStream compStream = new CompressedStream( sourceStream ) )
{
using( MemoryStream destinationStream = new MemoryStream() )
{
// 32K at at time.
byte[] buffer = new byte[ 32768 ];
int bytesRead = 0;
// Loop until we have nothing more to read from the source stream.
while( ( bytesRead = compStream.Read( buffer, 0, buffer.Length ) ) > 0 )
{
destinationStream.Write( buffer, 0, bytesRead );
}
// To get access to the MemoryStream's decompressed data, you can use:
byte[] decompressedData = destinationStream.ToArray();
// ToArray() works even when the memory stream is closed.
