How to Synchronously Execute an Async Task Method in C#?

Simultaneously execute C#asynchronous task

Method In the asynchronous programming,

The keywords are used to pause methods until the specific asynchronous operation is completed. However, in some cases, such as testing or interacting with other frameworks/components, the asynchronous method may be required synchronously.

await There are many ways to achieve this, but not all methods are suitable for all scenes. Here are some common methods:

Method 1: Use task.wait () method

blocking the current thread until the asynchronous operation is completed. But if the task is executed on the same thread that is waiting for it, it may lead to a deadlock.

Method 2: Use task.runsynachronously () method

Task.Wait()

Run asynchronous operations on the current thread without obstruction. But this method requires that the task is not bound to the commission, which is not always feasible.

<code class="language-csharp">Task<Customer> task = GetCustomers();
task.Wait();</code>

Method 3: Use TaskcompleTionSource class

Task.RunSynchronously() Allows manual creation tasks and completes it after the asynchronous operation is completed.

<code class="language-csharp">Task<Customer> task = GetCustomers();
task.RunSynchronously();</code>

Method 4: Use the custom auxiliary class Some third -party libraries provide auxiliary methods to run asynchronous tasks in synchronization. For example, asynchelpers library:

TaskCompletionSource<T> The best way depends on specific scenarios and application needs. When choosing a synchronous execution mechanism, be sure to consider potential dead locks and performance effects.
