AsOrdered C# with Example
This example shows how PLINQ can be used to calculate the even numbers between 1 and 10,000 using multiple threads. Order will be maintained in the resulting list, however keep in mind that AsOrdered may hurt performance for a large numbers of elements, so un-ordered processing is preferred when possible. var sequence = Enumerable.Range(1, 10000); var evenNumbers = sequence.AsParallel() .AsOrdered() .Where(x => x % 2 == 0) .ToList(); // evenNumbers = { 2, 4, 6, 8, ..., 10000 }
