So let’s say you have a few operations to run and it takes a while to finish the execution. You would like to know which step is taking so long and how to improve the performance of the application.
First, you could simply put a break point in each methods, but what if you want to be more precise and be able to give a report on the timing of the execution?
Create a timer or a StopWatch:
Stopwatch sw = new Stopwatch();
//Long task to measure
This is really useful for log files.
