Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

Dim gzip As ChilkatGzip
gzip.Initialize("gzip")

'  The string to be compressed:
Dim inputStr As String = "The quick brown fox jumps over the lazy dog."

'  Compress the string using UTF-8 and write to a file:
success = gzip.CompressStringToFile(inputStr, "utf-8", "output.gz")
If success = False Then
    Log(gzip.LastErrorText)
    Return
End If


Log("Compression successful.")
Log("Gzip file written to output.gz")
