How to calculate the code execution time in C#?

May 14, 2016· Execution Time: 100 ms In the above example, first we create an instance of the Stopwatch class. The Start() method starts measuring time for executing the code until we call the Stop() method. The ElapsedMilliseconds property gets the total time measured by the current instance in milliseconds. Here, it will return the time taken in executing the for loop.
