Await vs. Task.Wait: When Does Synchronous Blocking Create a Deadlock?

and : The trap of the deadlock await Task.Wait In asynchronous programming, understanding the difference between

and

is very important. This article will analyze a case that uses to cause dead locks. await Task.Wait Task.WaitAll : Synchronous blocking

will block the current thread simultaneously until the task is completed. In the example code, Waiting for the 10 tasks returned by the Task.Wait method to complete. This will block threads and prevent them from performing follow -up operations.

: Waiting asynchronous Task.Wait Task.WaitAll Ros() The allowable method will return the unfinished tasks to the caller while waiting for the task asynchronous. When the task is completed, the remaining code in the method is scheduled to be scheduled to be followed.

Dead lock scene await In the example code, the

method blocks the thread by calling

, and the await method calls the asynchronous method

and

to create a series of asynchronous operations. This effectively prevented the task from completing and release of threads. As a result, the method will never exit, resulting in dead locks. The obstruction operation in the asynchronous code

Get It is usually not recommended to use obstruction in asynchronous code. When the blocking occurs, the thread cannot handle the inlet request, resulting in a decline in performance and might be a deadlocked lock. Task.WaitAll Ros Conclusion Foo Bar The difference between Get understanding and

is essential for avoiding dead locks and effective use of asynchronous programming.

It should only be used in specific scenes that need to be synchronized. In most cases, it is recommended to use a "complete asynchronous" method to use to maintain asynchronous and prevent blocking problems in the entire code.
