    Decompressing a byte array
    In This Topic

    This topic demonstrates how to decompress a compressed byte array using the static Decompress method if the QuickCompression class.

    Basic steps

    To decompress a compressed byte array, the following steps must be taken:

    1. Retrieve a byte array containing the compressed data. For the purposes of this example, our compressed data is the data compressed using the Compress example. 

    2. Decompress the data. The resulting compressed data will be returned as a byte array.

    Demonstration

    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

    ' Note: Pathnames must be modified for code snippets to work under the .NET Compact Framework.

    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;

    // Note: Pathnames must be modified for code snippets to work under the .NET Compact Framework. 

    byte[] decompressedData = QuickCompression.Decompress( compressedData ); 

    // Display the decompressed data
    MessageBox.Show( System.Text.Encoding.Default.GetString( decompressedData ) );

    Things you should consider

    The main questions you should ask yourself when compressing data read from a stream are:

    • Do you want to decompress data as it is read from a stream? Use the Read method of the CompressedStream class. 

    • Do you need to convert the resulting decompressed byte array to a string? Use the GetString method of the .NET Framework's System.Text.Encoding class.
