Using the Parallel class

This recipe shows you how to use the Parallel class APIs. You will learn how to invoke methods in parallel, how to perform parallel loops, and tweak parallelization mechanics.

Getting ready

To work through this recipe, you will need Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter7\Recipe1.

How to do it...

To invoke methods in parallel, perform parallel loops, and tweak parallelization mechanics using the Parallel class, perform the given steps:

1. Start Visual Studio 2015. Create a new C# console application project.

2. In the Program.cs file, add the following using directives:

   using System;
   using System.Linq;
   using System.Threading;
   using System.Threading.Tasks;
   using static System.Console;
   using static System.Threading.Thread;

3. Add the following code snippet below the Main method:

   static string EmulateProcessing(string taskName)
   {
     Sleep(TimeSpan.FromMilliseconds(
       new Random(DateTime.Now.Millisecond...
