抽象代表注册

是否可以通过创建Function或其他方法，以某种方式抽象以下if/else语句，从而使此操作更通用，减少"重复"代码？

我有2个不同的类（生命周期和选择）和4个代表类型，如以下示例：

foreach (Delegate d in delegates)
{
  if (d.GetType ().Equals (typeof (LifeCycle.OnCreatedEvent)))
    Lifecycle.OnCreatedHandlers += (LifeCycle.OnCreatedEvent) d;
  else if (d.GetType ().Equals (typeof (LifeCycle.OnDeletedEvent)))
    LifeCycle.OnDeletedHandlers += (LifeCycle.OnDeletedEvent) d;
  else if (d.GetType ().Equals (typeof (Selection.OnSelectEvent)))
    Selection.OnSelectHandlers += (Selection.OnSelectEvent) d;
  else if (d.GetType ().Equals (typeof (Selection.OnDeselectEvent)))
    Selection.OnDeselectHandlers += (Selection.OnDeselectEvent) d;
}

我已经考虑过泛型，但我真的不确定如何以一种适当的、兼容的方式抽象接收/转换部分，从而接受+=操作。

有什么建议吗？

谢谢！

foreach (Delegate d in delegates)
{
    LifeCycle.OnCreatedHandlers  += d as LifeCycle.OnCreatedEvent;
    LifeCycle.OnDeletedHandlers  += d as LifeCycle.OnDeletedEvent;
    Selection.OnSelectHandlers   += d as Selection.OnSelectEvent;
    Selection.OnDeselectHandlers += d as Selection.OnDeselectEvent;
}
