One may find it interesting to know that IList does not inherit from IReadOnlyList, even though it has all the same members and all lists can be expressed as a read-only list. Immo Landwerth explains.

尽管IList接口与IReadOnlyList接口具有全部相同的成员、并且所有IList类型的列表都可表示为只读列表，但是IList不是继承自ireadonlylist，当有人得知这些以后可能会觉得很有趣。
