Define the term tracing

Question

Define the term tracing? And also explain that where it can be used?

Answer 1

Tracing displays details regarding the code that was executed. This refers to collecting information about application when it is running. The tracing information could help us to troubleshoot the application. This enables us to record information in a variety of log files about errors which might occur during run time. We can examine the log files to find cause of the errors.

In .NET, we have objects known as Trace Listeners. The listener is the object which gets a trace output and stores it to different places, like a file on your locale drive, the window, or a SQL Server.

System.Diagnostics namespace contains a classes,predefined interfaces, and structures which are used for the tracing. It provides two classes Debug and Trace that allows us to write errors and logs associated to application execution. Trace listeners are the objects which collect the output of the tracing processes.
