I've written a Windows Service using the .NET framework. I want to write
EventLogs to a text file, rather than to one of the EventLogs themselves.
I'm aware that this is something to do with using the
TextWriterTraceListener class which redirects output to an instance of the
TextWriter class or to anything that is a Stream class.

But I'm not sure how can this be done.
Any pointers?

Thanks

Dexter,

One of the easiest ways is to specify a trace listner in
the configuration files like this:

    <configuration>
        <system.diagnostics>
            <trace autoflush="true" indentsize="0">
                <listeners>
                    <add
                        name="MyListener"

type="System.Diagnostics.TextWriterTraceListener,System"

initializeData="MyListener.log"
                        />
                </listeners>
            </trace>
        </system.diagnostics>
    </configuration>

This gives you some runtime flexibility because if
you wanted you could then flip it over to record
in the event log (or both). The snippet above is
straight out of the SDK documentation for the <trace />
configuration element.

Once you have done this all you have to do is make
calls like this in your code:

    Trace.WriteLine("Doing something especially complicated here.");

Hope this helps.

A better approach to solving the problem is to centralize this code into
a component that you can get re-use out of. Microsoft has an exception
management application block on MSDN Downloads that provides an
infrastructure for publishing exception information. The default
publisher is to the Windows event log, but there is an interface defined
to publishing out to other sources (an example of publishing to an XML
document is included in the docs). This app block from MS is an
'exceptional' way of dealing with exceptions.
