作为c#工程师,c# list, set, map是否继承自collection接口?


在C#中,List<T>, Set<T>, 和 Dictionary<T, K> 这些集合类型都实现了 System.Collections.Generic.IEnumerable<T> 和 System.Collections.Generic.ICollection<T> 接口,但它们并没有直接继承自 Collection 接口。 Collection 接口在 System.Collections.Generic 命名空间下,它表示一个集合,可以被写入和读取,同时提供了枚举操作以及其他方法。它提供了一些方法和属性,如 Add, Remove, Contains, Count 等。 List<T> 是实现了 ICollection<T> 和 IList<T> 接口的类,主要提供了一种方便的方式去存储和访问一组对象。List<T> 可以包含重复的元素,并且可以动态地增加和减少元素。 Set<T> 是实现了 ICollection<T> 和 ISet<T> 接口的类,它是一个不包含重复元素的集合。Set<T> 的主要目的是提供一种不含重复元素的数据结构。 Dictionary<TKey, TValue> 是实现了 IDictionary<TKey, TValue> 接口的类,它提供了一种键值对的数据结构,可以快速地根据键来查找值。 虽然这些集合类型没有直接继承自 Collection 接口,但它们都实现了与 Collection 接口类似的方法和属性,因此在使用上可以看作是实现了 Collection 接口的集合类型。 [2023-11-09 17:55:07 | AI写代码神器 | 299点数解答]
