Best way to measure the execution time of methods [closed]

Answer 1

What I did was create an IDisposable class that would start a stopwatch in the constructor and stop/print the result in the dispose:

public class Superwatch : IDisposable
{
    static Stopwatch Watch = new Stopwatch();
    static Superwatch()
    {
        Watch.Start();
    }

    TimeSpan Start;
    public Superwatch()
    {
        Start = Watch.Elapsed;
    }

    public void Dispose()
    {
        TimeSpan elapsed = Watch.Elapsed - Start;
        Console.WriteLine($"Time elapsed: {elapsed}");
    }
} 

Then just pack the method into a using of an instance of the class you created.

using (var watch = new Superwatch())
{
      //piece of code
}

Not as clean as a decorator, but relatively clean imo and configurable for pieces of code.
