Examples

This example shows how to define a WriteDelegate that obtains a DataSet, and then writes the XML for the DataSet into the zip archive. There's no need to save the XML to a disk file first.

private void WriteEntry (String filename, Stream output)
{
    DataSet ds1 = ObtainDataSet();
    ds1.WriteXml(output);
}

private void Run()
{
    using (var zip = new ZipFile())
    {
        zip.AddEntry(zipEntryName, WriteEntry);
        zip.Save(zipFileName);
    }
}

Private Sub WriteEntry (ByVal filename As String, ByVal output As Stream)
    DataSet ds1 = ObtainDataSet()
    ds1.WriteXml(stream)
End Sub

Public Sub Run()
    Using zip = New ZipFile
        zip.AddEntry(zipEntryName, New WriteDelegate(AddressOf WriteEntry))
        zip.Save(zipFileName)
    End Using
End Sub

Remarks

When you add an entry and specify a WriteDelegate, via AddEntry(string, WriteDelegate), the application code provides the logic that writes the entry data directly into the zip file.
