Get Write, Trace, & Say The Numbers 11-20

Tracing helps to see the information of issues at the runtime of the application. By default Tracing is disabled. Tracing has the following important features: We can see the execution path of the page and application using the debug statement. We can access and manipulate trace messages programmatically.

The Trace class is in the System. Diagnostics namespace, additional documentation can be found on MSDN. When we start the Application from Visual Studio (with debugging) the output is written to the Output window or if you changed your VS configuration it might be written to the Immediate window instead.

TraceSource Class (System. Diagnostics) Provides a set of methods and properties that enable applications to trace the execution of code and associate trace messages with their source.

Trace log locations Console trace logs are saved in the trace log directories of the WebSphere Application Server node where the administration console is installed.

TraceSource provides tracing methods that allow you to easily trace events, trace data, and issue informational traces. In . NET Framework apps, trace output from TraceSource can be controlled by configuration file settings.

To define the TRACE conditional compilation symbol in C#, add the /d:TRACE option to the compiler command line when you compile your code using a command line, or add #define TRACE to the top of your file. In Visual Basic, add the /d:TRACE=True option to the compiler command line or add #Const TRACE=True to the file.

WriteLine(String) Writes a message to the trace listeners in the Listeners collection. WriteLine(Object, String) Writes a category name and the value of the object's ToString() method to the trace listeners in the Listeners collection.
