圣杰兄请教一个问题下,我结合了Autofac实现了事件总线的注册和Trigger的解耦,但是唯独Action的注册和调用没法通过Autofac做到,后面尝试使用反射实现也没办法,原因是ActionEventHandler的构造函数就是一个Action,希望 圣杰兄帮忙指点下。这是我触发事件的那一段代码:
public void Trigger(TEventData eventData) where TEventData : IEventData { //从事件映射集合里获取匹配当前EventData(事件源数据)的Handler List handlerTypes = _eventStore.GetHandlersForEvent(eventData.GetType()).ToList(); if (handlerTypes.Count <= 0) return; //循环执行事件处理函数 foreach (var handlerType in handlerTypes) { var handlerInterface = handlerType.GetInterface("IEventHandler`1"); var eventHandler = ContainerManager.Current.Container.Resolve(handlerInterface); if (eventHandler.GetType().FullName == handlerType.FullName) { var handler = eventHandler as IEventHandler; handler?.HandleEvent(eventData); } else { //如果Ioc容器里没有则需要反射生成 //因为ActionEventHandler的构造函数需要有指定的入参:Action,这里没法反射!! MethodInfo methodInfo = handlerType.GetMethod("HandleEvent").MakeGenericMethod(); if (methodInfo != null) { object obj = Activator.CreateInstance(handlerType); methodInfo.Invoke(obj, new object[] { eventData }); } } }
}
