Creating a Zip File with Multiple Entries

To stream multiple XML files directly into the zip file, use the OpenWriter method. That returns a stream that you can write to, and when the stream is closed it is added to the zip file.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim zip As New C1ZipFile()

    zip.Create("c:\temp\test.zip")

    Dim s As Stream = zip.Entries.OpenWriter("entry1", True)

    Dim sw As New C1ZStreamWriter(s)

    sw.WriteLine("Hello world")

' Continue writing as much as you want...

    sw.Close()

    s = zip.Entries.OpenWriter("entry2", True)

    sw = New C1ZStreamWriter(s)

    sw.WriteLine("Hello again")

' Continue writing as much as you want...

    sw.Close()

End Sub

private void button1_Click(object sender, System.EventArgs e)

    C1ZipFile zip = new C1ZipFile();

    zip.Create(@"c:\temp\test.zip");

    Stream s = zip.Entries.OpenWriter("entry1", true);

    C1ZStreamWriter sw = new C1ZStreamWriter(s);

    sw.WriteLine("Hello world");

// Continue writing as much as you want...

    sw.Close();

    s = zip.Entries.OpenWriter("entry2", true);

    sw = new C1ZStreamWriter(s);

    sw.WriteLine("Hello again");

// Continue writing as much as you want...

    sw.Close();

To read an entry without saving it to a file, use the OpenReader method on the entry object.
