Question

I need to measure the execution of many different methods within the context of an application.

.NET of course has the Stopwatch class which allows one to easily time a section of code with it’s .Start() and .Stop() methods.

However, use of the Stopwatch class in its normal manner requires me to decorate every method with an instance of a Stopwatch object and calls to it’s .Start() and .Stop() methods.

I need to use Stopwatch functionality on literally hundreds of methods and do not want to pollute every method with this code. I would also like to have the ability to turn timing on and off.

Is there a simple way I can implement a generic timing solution within my own code? If so, how? Code profilers do it, so I think it must be possible.

Just a thought. declare a method as below

public static long Measure(Action action)
{
    Stopwatch sw = Stopwatch.StartNew();
    action();
    return sw.ElapsedMilliseconds;
}

and use as

var duration = Measure(() => MyMethod(param1));
