Remarks

处理程序不需要执行任何操作,你的代码应避免生成异常或允许异常传播到调用方法。The handler is not required to perform any action, and your code should avoid generating exceptions or allowing exceptions to propagate to the calling method. 任何访问调用方的异常都将被忽略。Any exceptions that do reach the caller are ignored.

创建 SqlRowUpdatedEventArgs 委托时,需要标识将处理该事件的方法。When you create a SqlRowUpdatedEventArgs delegate, you identify the method that will handle the event. 若要将事件与事件处理程序关联,请将该委托的一个实例添加到事件中。To associate the event with your event handler, add an instance of the delegate to the event. 除非移除了该委托,否则每当发生该事件时就会调用事件处理程序。The event handler is called whenever the event occurs, unless you remove the delegate. 有关事件处理程序委托的详细信息,请参阅处理和引发事件For more information about event handler delegates, see Handling and Raising Events.
