In our last installment we found our hero investigating the tracing changes found in Connector/Net 6.2.  This time we’ll take a closer look at the format of the trace data and how developers can use that information to write new and interesting trace listeners.

Understanding the plumbing

The first thing we need to understand is a little about how the trace messages are routed.  The main method we are interested in is TraceSource.TraceEvent.  Here is the signature.

public void TraceEvent(
    TraceEventType eventType,
    int id,
    string format,
    params Object[] args
)

All the other TraceSource methods like TraceInformation eventually boil down to a call to …

For years, Connector/Net has been a key part of any MySQL & .NET developer’s toolbox.  Tracing is also a key part of a developer’s life and Connector/Net has always output trace messages. 

This first post is a review of .NET tracing systems and how we changed our trace output.  The second post will cover how developers can use the new tracing format to develop new applications.

Tracing in .NET 1.x

.NET shipped with a very simple tracing system.  You have a static class named Trace that has static methods such as Write and WriteLine.  An application can use code like the following to output a message to the trace log. 

Now that we have output our message, how do we direct it somewhere?  You do that with listeners.  There are a few standard listeners included in the framework (ConsoleTraceListener, XmlTraceListener, EventLogTraceListener) but you …
