Should I Stop Stopwatch at the end of the method?

Question

Let's imagine we have simple measurements using Stopwatch

public void DoWork()
{
    var timer = Stopwatch.StartNew();
    // some hard work
    Logger.Log("Time elapsed: {0}", timer.Elapsed);
    timer.Stop(); // Do I need to call this?
}

According to MSDN:

In a typical Stopwatch scenario, you call the Start method, then eventually call the Stop method, and then you check elapsed time using the Elapsed property.

I'm not sure if I should call this method when I'm no longer interested with timer instance. Should I "clear up" using Stop method?

EDIT

Keep in mind that Logger.Log(..) costs nothing because timer.Elapsed is read before the logger logs.

No, you don't need to stop it. Stop() just stops tracking elapsed time. It does not free up any resources.
