Calculating the execution time of each functions/methods

How can we calculate the execution time of each functions/methods in any project so that we should know which funtion is take so much time and we need to work on that?

Is there any prebuild method or property so that we can calculate the execution time?

If you have knowledge of Data Structures  (which is usually course in Computer Sciences field), you may have imagination of how to calculate execution time.

Anyway, you can try something like this:

1. Create DateTime dtStart = DateTime.Now;

2. Call the function you want to test

3. After function call line, add DateTime dtEnd = DateTime.Now

At last, create TimeSpan ts = dtEnd - dtStart

Example:

DateTime dtStart = DateTime.Now;

functionName(params);

DateTime dtEnd = DateTime.Now;

TimeSpan ts = dtEnd - dtStart;

// you have the  time in the ts value so play with it :).

Thankx for the suggestion for this logic.

Go with profilers. There are many, I will suggest to go with ANTS Performance Profiler™ and dotTrace
