        (filename,System.IO.FileMode.Create);

    // Create a new XmlTextWriter object with the FileStream.
    System.Xml.XmlTextWriter writer =
        new System.Xml.XmlTextWriter(stream,
        System.Text.Encoding.Unicode);

    // Write the schema into the DataSet and close the reader.
    thisDataSet.WriteXmlSchema(writer );
    writer.Close();
}

Private Sub WriteSchemaWithXmlTextWriter(thisDataSet As DataSet)
    ' Set the file path and name. Modify this for your purposes.
