C# Problem..

I know the title looks strange.. but this issue is provoking me to a very high extent...
I'll tell u why I wrote so...well, When we were testing our Algo project b4 delivering it, we noticed a strange behavior in the performance of our code..
Let me explain wt we were doing first... well, we wanted to calculate the approximate time taken to run the algorithm.. so we made an object from Stopwatch class.. our code looked sth like those lines:

Stopwatch s = new StopWatch();
s.Start();
OurFunction();
s.Stop();

Then later on we display the elapsed time.... Where's the problem then??.. well I will tell u.. the first time we try calling this function, the elapsed time is 4.xxx ms.. while when we try the same input once again (while the exe is still running).. the elapsed time is 0.xxxx.. a gr8 difference !!!!
well.. we noticed sth in our function like creating an object from a class we created.. ex:
Class c = new Class(Var1,Var2); //inside function's body

we thought that this was the reason (sth related with memory allocation , variables initialization.. etc..) we tried initializing everything globally, but still the same thing happened.. we thought about many things (We with the help of Dr Karim), but all in vain..

So, I still don't know why that happens.. mm.. Maybe C# is googling for the place of the function in the memory when we call it for the first time ,so it takes more time !!???

Anyway, please, If anyone has any idea about why this may happen.. Comments are very welcomed..
