However, I am keen to understand if there are any downsides. For example, is it something that is in widespread use and is transparent enough that it won't cause a maintenance headache? Is there any appreciable performance hit of the empty event subscriber call?
推荐答案
唯一的缺点是非常轻微的性能损失，因为您调用了额外的空委托.除此之外，没有维护费用或其他缺点.
The only downside is a very slight performance penalty as you are calling extra empty delegate. Other than that there is no maintenance penalty or other drawback.
