Apply function to all elements of collection through LINQ [duplicate]

Answer 1

You could also consider going parallel, especially if you don't care about the sequence and more about getting something done for each item:

SomeIEnumerable.AsParallel().ForAll( Action / Delegate / Lambda )

For example:

var numbers = new[] { 1, 2, 3, 4, 5 };
numbers.AsParallel().ForAll( Console.WriteLine );

HTH.
