Both implement IList<T> and hold the data in an ordered fashion, but only List expose the sorting semantics....
两者都实现 IList<T> 并以有序的方式保存数据，但只有 List 公开排序语义....

Collection<T>:Provides the base class for a generic collection.
List<T>:Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.
Collection<T>：提供泛型集合的基类。
List<T>：表示可以通过索引访问的对象的强类型列表。提供搜索、排序和操作列表的方法。
So, according the docs, one is intended as a base class for collections. The other is intended for use as a container.
因此，根据文档，一个旨在作为集合的基类。另一个用作容器。
So useList<T>and inheritfrom Collection<T>.
所以使用List<T>并继承自Collection<T>.
