C#和.Net为什么所有数组都继承自IList? [英] C# and .Net why do all arrays inherit from IList?

问题描述

我最近注意到C#中的所有数组都是从IList接口继承的，但是您不能真正像标准列表那样处理数组.

I recently noticed that all arrays in C# inherit from the IList interface but you can't really handle an array like a standard list.

为什么在.net和C#中引入这种继承

Why was this inheritance introduced in .net and C#

推荐答案

能够将 any IList传递给某种算法通常很有用.该算法可能只是关心能够索引到该集合中.许多东西都可以满足此要求:数组，List<T>，许多自定义集合.

It is often useful to be able to pass any IList to some algorithm. That algorithm might just care about being able to index into this collection. Many things fulfill this requirement: Arrays, List<T>, many custom collections.
