Tracing allows you to keep track of the application, how it is performing, what errors are produced etc
Being able to collect information about an application is extremely useful when trying to track down errors and improving performance.
The System.Diagnostics.DebuggerStepThrough attribute can be used on class properties and methods when you don't want the debugger to step into them
Check the Options
Define TRACE constant - Build tab
This is a compilation constant
For any of this to happen you must make sure the option is selected
A release solution configuration includes all the Debug class methods
Trace switches allow you to enable, disable and filter tracing output
They can be configured externally in the .config file
A trace listener is an object that receives output and sends it somewhere else.
All the trace listeners are derived from the abstract TraceListener class.
If you inherit from this class then you must at least implement the Write and WriteLine methods.
The System.Diagnostics namespace somes with several trace listeners built in.
DefaultTraceListener - created and enabled automatically when tracing or debugging is enabled
This is the default trace listener and is used when we want to see tracing output in the Visual Studio editor.
If we want to capture messages outside of Visual Studio then you must use a different trace listener.
TextWriterTraceListener - used to log to a file
This type of trace listener will redirect the tracing output to an instance of the TextWriter class or to any stream, for example a log file, console etc.
[copy code from Tracer_Start
EventLogTraceListener - used to log to windows event viewer
This type of trace listener will direct the tracing output to the windows event log
This class can even be used to direct the output to a remote computer.
|Close||closes the stream to receive no more output|
|Fail||outputs the text with the call stack|
|Flush||flushes the output buffer|
|Write||outputs the text|
|WriteLine||outputs the text with a carriage return|
