What is the system.diagnostic.trace class?
The System.Diagnostics.Trace class is the cornerstone of instrumentation and allows you to write tracing code that sends diagnostic information to all of the current trace listeners. It has several methods for this purpose. I describe these methods in the sections that follow.
Why do you need to switch off tracing?
This is necessary because you usually don't need to produce copious amounts of tracing information unless your testers or your end users are actually seeing a problem. During normal everyday use, you probably want to switch off most of the instrumentation to improve performance and to avoid generating useless information.
What is the purpose of System.Diagnostics.EventLogTraceListener class?
The System.Diagnostics.EventLogTraceListener class allows you to direct tracing information to any of the Windows event logs. This can be very useful, especially for middle- tier application servers where administrators often expressly monitor these logs. It can also be useful for remote diagnostics because you can easily view another machine's Windows event log using your machine's event viewer if you have the right permissions.
What is the Write Line method?
The Write and WriteLine Methods. The Write method is used to produce diagnostic information without a linefeed , so that further information can then be appended to the same line. The Write-Line method is used to produce diagnostic information with a linefeed.
