注解

使用EventInfo类来检查事件,并挂接事件处理程序中的代码示例所示AddEventHandler方法。Use the EventInfo class to inspect events and to hook up event handlers, as shown in the example code for the AddEventHandler method.

备注

EventInfo 不是要用来引发事件。EventInfo is not intended to be used to raise events. 对象由其内部状态指示引发事件。An object raises events as dictated by its internal state.

事件与委托一起使用。Events are used with delegates. 事件侦听器实例化时引发的事件源调用的事件处理程序委托。An event listener instantiates an event-handler delegate that is invoked whenever the event is raised by an event source. 若要连接到事件源,事件侦听器将此委托添加到源上的调用列表。In order to connect to the event source, the event listener adds this delegate to the invocation list on the source. 当引发事件时,调用事件处理程序委托的 invoke 方法。When the event is raised, the invoke method of the event-handler delegate is called. 支持这两个多路广播和单路事件通知。Both multicast and single-cast event notifications are supported. AddRemove必须在元数据中标记方法,以及与事件相关联的事件处理程序委托类。The Add and Remove methods, as well as the event-handler delegate class associated with an event, must be marked in the metadata.

委托是面向对象的函数指针。Delegates are object-oriented function pointers. 在 C 或 c + + 中,函数指针是一种方法对的引用。In C or C++, a function pointer is a reference to a method. 委托与 C 或 c + + 函数指针不同包含两个引用: 对方法,并对支持该方法的对象的引用的引用。In contrast to the C or C++ function pointer, a delegate contains two references: a reference to a method and a reference to an object that supports the method. 委托可以调用的方法,而不必知道类类型声明或继承的方法。Delegates can invoke a method without knowing the class type that declares or inherits the method. 委托只需知道该方法的返回类型和参数列表。Delegates need only know the return type and parameter list of the method.

事件模型同样适用于单强制转换和多路广播委托。The event model works equally well for single-cast and multicast delegates. 当调用委托的调用时调用方法时,只有单个对象可以对其进行调用的方法。When the delegate's invoke method is called, only a single object will have a method called on it. 多路广播的修饰符可以应用于委托声明,它允许多个方法时调用该委托的 invoke 方法调用。A multicast modifier can be applied to a delegate declaration, which allows multiple methods to be called when the invoke method of the delegate is called.

调用ICustomAttributeProvider.GetCustomAttributesEventInfoinherit参数GetCustomAttributestrue不会遍历类型层次结构。Calling ICustomAttributeProvider.GetCustomAttributes on EventInfo when the inherit parameter of GetCustomAttributes is true does not walk the type hierarchy. 使用System.Attribute继承的自定义特性。Use System.Attribute to inherit custom attributes.

继承者说明
