I found a simple code to know the execution time of a method. First of all you have to import the following namespace:
using System.Diagnostics;
Then you use Stopwatch to know the execution time.
Stopwatch sw = Stopwatch.StartNew();
DoSomeWork();
sw.Stop();
Console.WriteLine("Time taken: {0}ms", sw.Elapsed.TotalMilliseconds);
Happy coding!
