Write asynchronous method c#

When no result value is needed, an async Task method is better than an async void method because it allows the caller to also use await to wait for it, making ordering and exception handling easier. Let's start by updating this code so that the thread doesn't block while tasks are running.

That signals to the compiler that this method contains an await statement; it contains asynchronous operations.

The core actions are still clear from reading the code. You should use void when you know that no caller will ever need to know when the operation is finished or whether it succeeded. Before serving breakfast, you want to await the task that represents toasting the bread before adding butter and jam.

Once the asynchronous method completes the execution, the async methods updates the state to Task object marking it completed and the string value is returned to msg variable.

Consider applying the await operator to the result of the call.

Asynchronous programming: Microsoft Docs Concept. Note: An async method will be run synchronously if it does not contain the await keyword. We perform some computations. Writing Async Methods Now we know how great asynchronous code is, but how hard it is to write? And: Thanks to Andrew Dennison for reviewing the Allocate method code which had an unnecessary statement. It looks much more like the original synchronous version of the code. With these keywords, we run methods in an asynchronous way. Its exception will not be observed, and depending on. Display its results. C program that shows await operator warnings using System; using System. Your application shouldn't make a phone appear frozen while it's downloading data from the web. Async methods must contain await.

It looks much more like the original synchronous version of the code. Sometimes the wrong Task can be waited on. All rights reserved. Some C syntax features can help here—we can use a local method declaration InnerMethod in the example.
