This recipe shows how to program a Lazy-evaluated, thread-safe shared state object.
To start this recipe, you will need to run Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter10\Recipe1
.
To implement Lazy-evaluated shared states, perform the following steps:
Start Visual Studio 2015. Create a new C# console application project.
In the
Program.cs
file, add the followingusing
directives:using System; using System.Threading; using System.Threading.Tasks; using static System.Console; using static System.Threading.Thread;
Add the following code snippet below the
Main
method:static async Task ProcessAsynchronously() { var unsafeState = new UnsafeState(); Task[] tasks = new Task[4]; for (int i = 0; i < 4; i++) { tasks[i] = Task.Run(() => Worker(unsafeState)); } await Task.WhenAll(tasks); WriteLine(" --------------------------- "); ...
