事件处理程序是否异步处理？ [英] Are Event Handlers processed Asynchronously?

问题描述

在VB .NET中，当调用RaiseEvent X（）时，是处理异步处理或同步处理的事件X的函数。我的印象是RaiseEvent和事件的处理是同步的，除非在另一个线程上明确地创建。除非另有说明，否则我会被告知。

In VB .NET, when you call RaiseEvent X(), is the function that handles the event X processed asynchronously or synchronously. I was under the impression that RaiseEvent and the processing of the event were Synchronous unless created explictly on another thread. I've been told otherwise though.

推荐答案

由于 MulticastDelegates 被设计为支持异步调用，可以异步调用事件的调用列表中的委托，但这不是默认行为。

Events are raised synchronously by default. Since MulticastDelegates are designed to support asynchronous invocation it is possible to invoke the delegates in an event's invocation list asynchronously but this is not the default behavior.
