c#  Task.FromResult 的基本用法和实例

This method is useful when you perform an asynchronous operation that returns a Task object, and the result of that Task object is already computed

There are two common use cases I‘ve found:

  1. When you‘re implementing an interface that allows asynchronous callers, but your implementation is synchronous.
  2. When you‘re stubbing/mocking asynchronous code for testing

上面总体来说是用于单元测试;

然后还有在我们读取缓存的时候有用; 微软官方博客实例;

上面的思想:

This method is useful when you perform an asynchronous operation that returns a Task object, and the result of that Task object is already computed.

已经计算出来了,或者已经缓存好了,基本想要的值;
