You need to output trace
information in an XML format. Unfortunately, the
Debug classes are
sealed and therefore cannot be inherited from in order to create more
specialized classes. This limitation poses somewhat of a problem if
you need to create a
Debug class that outputs XML instead of plain
text. You could start from scratch and build new
Debug classes from
the ground up, but you would have to handle configuration files,
listener collections, and switch information, among other things.
This way can become quite time-consuming; you need a better way.
You could use the Log4Net package found at the SourceForge web site (http://log4net.sourceforge.net); it is a complete logging system that can easily be added to your application. However, if you use the XML logging, you should realize that the XML output is not well-formed. This is done by design so that the XML fragments output from Log4Net can be included as external entities in a different XML file to create a well-formed XML file.
Another solution is to create a new trace
listener class, such as
inherits from the framework-provided
XMLTraceListener class is defined as
follows (note that the
