(C#) Decompress Gzip Data In-Place Using BinData

See more Gzip Examples

This example demonstrates how to use the UncompressBd method to decompress Gzip data stored in a BinData object.

The compressed .gz file is first loaded into memory. The UncompressBd method then decompresses the data in-place, meaning the original compressed bytes in the BinData object are replaced with the uncompressed data.

After decompression, the example writes the resulting data to a file. This approach is useful when working entirely in memory before saving or further processing the uncompressed data.

Chilkat.Gzip gzip = new Chilkat.Gzip();
Chilkat.BinData bd = new Chilkat.BinData();

// Load a .gz file into BinData:
success = bd.LoadFile("example.txt.gz");

    Debug.WriteLine(bd.LastErrorText);
    return;
}

Debug.WriteLine("Compressed size (bytes): " + Convert.ToString(bd.NumBytes));

// Uncompress the data in-place:
success = gzip.UncompressBd(bd);
if (success == false) {
    Debug.WriteLine(gzip.LastErrorText);
    return;
}

Debug.WriteLine("Decompressed size (bytes): " + Convert.ToString(bd.NumBytes));

// Save the uncompressed data to a file:
success = bd.WriteFile("example.txt");
if (success == false) {
    Debug.WriteLine(bd.LastErrorText);
    return;
}

Debug.WriteLine("File successfully uncompressed to example.txt");
