是事件处理程序处理异步？ [英] Are Event Handlers processed Asynchronously?

问题描述

在VB .NET中，当你调用的RaiseEvent X（），是处理点¯x同步或异步处理事件的函数。我是IM pression说的RaiseEvent和事件的处理是同步，除非显式地在另一个线程创建下。有人告诉我，否则虽然。

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

事件被同步默认情况下提出的。由于<一个href=\"http://msdn.microsoft.com/en-us/library/system.multicastdelegate.aspx\"><$c$c>MulticastDelegates旨在支持异步调用，可以调用在异步事件的调用列表代表，但这不是默认的行为。

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.
