Overview of this book

During your application development workflow, there is always a moment when you need to get out of a tight spot. Through a recipe-based approach, this book will help you overcome common programming problems and get your applications ready to face the modern world. We start with C# 6, giving you hands-on experience with the new language features. Next, we work through the tasks that you perform on a daily basis such as working with strings, generics, and lots more. Gradually, we move on to more advanced topics such as the concept of object-oriented programming, asynchronous programming, reactive extensions, and code contracts. You will learn responsive high performance programming in C# and how to create applications with Azure. Next, we will review the choices available when choosing a source control solution. At the end of the book, we will show you how to create secure and robust code, and will help you ramp up your skills when using the new version of C# 6 and Visual Studio

Cancelling a parallel foreach loop


When dealing with parallel foreach loops, the obvious question is how one would terminate the loop prematurely based on a certain condition, such as a timeout. As it turns out, the parallel foreach loop is quite easy to terminate prematurely.

Getting ready

We will create a method that takes a collection of items and loops through this collection in a parallel foreach loop. It will also be aware of a timeout value that, if exceeded, will terminate the loop and exit the method.

How to do it…

  1. Start off by creating a new method called CancelParallelForEach() in the Recipes class, which takes two parameters. One is a collection of List<string>, while the other is an integer specifying a timeout value. When the timeout value is exceeded, the Parallel.ForEach loop must terminate:

    public class Recipes
    {
        public void CancelParallelForEach(List<string> intCollection, int timeOut)
        {        
    
        }    
    }
  2. Inside the CancelParallelForEach() method, add a...
