Multithreading with C# Cookbook, Second Edition - Second Edition

By: Evgenii Agafonov

Overview of this book

Multi-core processors are synonymous with computing speed and power in today’s world, which is why multithreading has become a key concern for C# developers. Multithreaded code helps you create effective, scalable, and responsive applications. This is an easy-to-follow guide that will show you difficult programming problems in context. You will learn how to solve them with practical, hands-on, recipes. With these recipes, you’ll be able to start creating your own scalable and reliable multithreaded applications. Starting from learning what a thread is, we guide you through the basics and then move on to more advanced concepts such as task parallel libraries, C# asynchronous functions, and much more. Rewritten to the latest C# specification, C# 6, and updated with new and modern recipes to help you make the most of the hardware you have available, this book will help you push the boundaries of what you thought possible in C#.

Implementing asynchronous processing using ConcurrentQueue


This recipe will show you an example of creating a set of tasks to be processed asynchronously by multiple workers.

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\Chapter6\Recipe2.

How to do it...

To understand the working of creating a set of tasks to be processed asynchronously by multiple workers, perform the following 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.Collections.Concurrent;
    using System.Threading;
    using System.Threading.Tasks;
    using static System.Console;
  3. Add the following code snippet below the Main method:

    static async Task RunProgram()
    {
      var taskQueue = new ConcurrentQueue<CustomTask>();
      var cts = new CancellationTokenSource();
    
      var taskSource = Task.Run(() => TaskProducer...
