Using ConcurrentDictionary

This recipe shows a very simple scenario, comparing the performance of a usual dictionary collection with the concurrent dictionary in a single-threaded environment.

Getting ready

To work through this recipe, you will need Visual Studio 2012. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter6\Recipe1.

How to do it...

To understand the difference between performance of a usual dictionary collection with the concurrent dictionary, perform the following steps:

1. Start Visual Studio 2012. 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.Collections.Generic;
   using System.Diagnostics;

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

   const string Item = "Dictionary item";
   public static string CurrentItem;

4. Add the following code snippet inside the Main method:

   var concurrentDictionary = new ConcurrentDictionary...
