C#中为什么 List<T>类实现了IList接口又实现 ICollection接口啊？IList接口已经实现了 ICollcetion接口啊

如题 ,我的理解是既然实现了IList接口，那么似乎实现ICollection接口是多余的了啊，因为IList接口已经继承自ICollection接口。

你没发现么？IList继承的只是ICollection 接口，而List<T> 实现的是ICollection<T>接口么？一个是泛型的，一个不是泛型的啊…… ICollection<T>是.Net2.0出现 泛型思想以后 添加的接口。原来的时候只有ICollection，所以List<T>为了 兼容以前的把ICollection<T>接口也实现啦啊
