My program is about triggering XSL transformation,

Its fact that this code for carrying out the transformation, creates some dll and tmp files and deletes them pretty soon after the transformation is completed.

It is almost untraceable for me to monitor the creation and deletion of files manually, so I want to include some chunk of codelines to display "which codeline has created/modified which tmp and dll files" in console window.

This is the relevant part of the code:

            string strXmlQueryTransformPath = @"input.xsl";
            string strXmlOutput = string.Empty;
            StringReader srXmlInput = null;
            StringWriter swXmlOutput = null;
            XslCompiledTransform xslTransform = null;
            XPathDocument xpathXmlOrig = null;
            XsltSettings xslSettings = null;

            MemoryStream objMemoryStream = null;
            objMemoryStream = new MemoryStream();

            xslTransform = new XslCompiledTransform(false);
            xpathXmlOrig = new XPathDocument("input.xml");

            xslSettings = new XsltSettings();
            xslSettings.EnableScript = true;
            xslTransform.Load(strXmlQueryTransformPath, xslSettings, new XmlUrlResolver());

            xslTransform.Transform(xpathXmlOrig, null, objMemoryStream);
            objMemoryStream.Position = 0;
            StreamReader objStreamReader = new StreamReader(objMemoryStream);
            strXmlOutput = objStreamReader.ReadToEnd();
// make use of Data in string "strXmlOutput"

google and msdn search couldn't help me much..
