Add Text from a StringBuilder to a ZIP Using AddSb

See more Zip Examples

This example demonstrates how to use the AddSb method to add text from a StringBuilder object as a file entry within a ZIP archive.

The text is converted to bytes using the specified character encoding before being stored in the ZIP archive.

This method is useful for dynamically generating text files entirely in memory without creating temporary files on disk.

VB.NET

Dim success As Boolean = False

Dim zip As New Chilkat.Zip

success = zip.NewZip("stringBuilderData.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Create a StringBuilder containing text data.
Dim sb As New Chilkat.StringBuilder

sb.AppendLine("Line 1: Hello World!",True)
sb.AppendLine("Line 2: This text came from a StringBuilder.",True)

' Add the StringBuilder contents as a UTF-8 text file
' stored in the ZIP archive as "docs/readme.txt".
success = zip.AddSb("docs/readme.txt",sb,"utf-8")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Write the ZIP archive to disk and close it.
success = zip.WriteZipAndClose()
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("ZIP archive created successfully.")
