How to write an xsl trasform to stream?

[pax82]

hi, sorry for my english but i don't speak good english.

in this web service i send 2 data stream(xml and xsl file) and i would like to return a xslt trasform-file byte array (now i return string because i'm in testing)
when the transResult file is been created, it's source is all NULL char.
why? where i'm wrong?

    public string getData(byte[] xmlData, byte[] xslData)
    {
 
        string workDir = "D:\\provaWebService\\";
 
 
        int xmlFileSize = xmlData.Length;
        int xslFileSize = xslData.Length;
 
 
        Stream xmlStreamData = new MemoryStream(xmlData);
        Stream xslStreamData = new MemoryStream(xslData);
        Stream output = new MemoryStream();
 
        XPathDocument XPathDoc = new XPathDocument(xmlStreamData);
        XslCompiledTransform xslTrans = new XslCompiledTransform();
 
        XmlReader reader = XmlReader.Create(xslStreamData);
 
        xslTrans.Load(reader);
 
 
        output.Position = 0;
        XmlTextWriter writer = new XmlTextWriter(output,Encoding.UTF8);
        writer.Formatting = Formatting.Indented;
 
        xslTrans.Transform(XPathDoc.CreateNavigator(), null, writer);
 
 
        FileStream outFile = new FileStream(workDir + "result.html", FileMode.Create);
        byte[] byteArray = new byte[output.Length];
        int numBytesToRead = (int)output.Length;
        int n = output.Read(byteArray, 0, numBytesToRead);
 
        outFile.Write(byteArray, 0, byteArray.Length);
        outFile.Close();
 

Thanks,
P.
