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.

VB.NET

Dim success As Boolean = False

' This example demonstrates how to compress a string and save the result
' directly to a Gzip (.gz) file.

Dim gzip As New Chilkat.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
    Debug.WriteLine(gzip.LastErrorText)
    Exit Sub
End If


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