所有Web API异步等待方法的全局try catch处理程序

Question

I am aware of the fact that await operator is clean and if used with async/await all the way down it will throw the exceptions properly.

I have a bulk of API calls (Web API) written in controllers which uses async await all the way down. Is there any way to write a common try catch for all those async await methods or do I need to go for a harder way to add try catch in each of those API methods to handle all the unhandled exceptions.

Answer 1

You can write an exception filter .

Note that exception filters apply whether or not the method is async . The same exception filter will work fine for both synchronous and asynchronous methods that throw exceptions.
