Silverlight 4中的C#处理队列

你可以做一个 IAction Execute Completed 事件

s和流行音乐 当前项的处理程序。

您甚至可以创建一个迭代器方法 yield return s IAction MoveNext() 之后 IAction

编辑 :例如:

class ActionEnumerator : IAction {
    readonly IEnumerator<IAction> enumerator;
    public ActionEnumerator(IEnumerator<IAction> enumerator) {
        this.enumerator = enumerator;
    }

    public void Execute() {
        //If the enumerator gives us another action,
        //hook up its Completed event to continue the
        //the chain, then execute it.
        if (enumerator.MoveNext()) {
            enumerator.Current.Completed += delegate { Execute(); };
            enumerator.Current.Execute();
        } else     //If the enumerator didn't give us another action, we're finished.
            OnCompleted();
    }
}

IEnumerator<IAction> SomeMethod() { 
    ...
    yield return new SomeAction();
    //This will only run after SomeAction finishes
    ...
    yield return new OtherAction();
    ...
}
