    For and Foreach loops are common and tremendously powerful constructs. Many times when using these constructs,each iteration depends on a calculation or action in the previous iteration. But this isn’t always the case.If the iterations are independent of each other, and you’re running on a multiprocessor machine, it might be a huge advantage if you could put different iterations on different processors and process them in parallel. This is exactly what the

    Parallel.For and Parallel.ForEach constructs do.
