EventInfos 类
Contains a collection of EventInfo objects. The run-time engine exposes an EventInfos collection on all containers in the package hierarchy. The collection that a task receives is a reference to EventInfos collection on the TaskHost that is wrapping the task. Other containers' EventInfos collections contain aggregated contents of their children’s EventInfos collections. This class cannot be inherited.

注释
The EventInfos collection is used to hold custom events and events that you want the task to raise during execution. When creating a custom task, use this class to add your own custom events to the runtime.
