In this recipe, you will learn how to use await
to run asynchronous operations in parallel instead of the usual sequential execution.
To step 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\Chapter5\Recipe4
.
To understand the use of the await
operator for parallel asynchronous task execution, 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.Tasks; using static System.Console; using static System.Threading.Thread;
Add the following code below the
Main
method:static async Task AsynchronousProcessing() { Task<string> t1 = GetInfoAsync("Task 1", 3); Task<string> t2 = GetInfoAsync("Task 2", 5); string[] results = await Task.WhenAll(t1...
