Implementing a loop using a timer in C#

Question

I wanted to replace a counter based while loop with the timer based while loop in C#.

Example :

while(count < 100000)
{
   //do something 
}

You might as well use the DateTime.Now.Ticks counter:

long start = DateTime.Now.Ticks;
TimeSpan duration = TimeSpan.FromMilliseconds(1000);
do
{
  //
}
while (DateTime.Now.Ticks - start < duration);

However, this seems to be something like busy waiting. That means that the loop will cause one core of your CPU to run at 100%. It will slow down other processes, speed up fans a.s.o. Although it depends on what you intend to do I would recommend to include Thread.Sleep(1) in the loop.
