Add Text Files to a ZIP Using AddString

See more Zip Examples

This example demonstrates how to use the AddString method to add multiple text files directly from string variables into a ZIP archive.

Each string is converted to bytes using the specified character encoding and stored as a separate file entry within the ZIP archive.

This method is useful for dynamically generating small text files such as configuration files, reports, JSON documents, XML, or log files entirely in memory.

VB.NET

Dim success As Boolean = False

Dim zip As New Chilkat.Zip

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


' Add a README text file.
Dim readmeText As String = "This ZIP archive was created using AddString."

success = zip.AddString("docs/readme.txt",readmeText,"utf-8")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Add a JSON configuration file.
Dim jsonText As String = "{ ""server"": ""example.com"", ""port"": 443 }"

success = zip.AddString("config/settings.json",jsonText,"utf-8")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Add a small XML document.
Dim xmlText As String = "<root><status>OK</status></root>"

success = zip.AddString("xml/status.xml",xmlText,"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.")
