定义

提供用于集的抽象的基接口。Provides the base interface for the abstraction of sets.

generic <typename T>
public interface class ISet : System::Collections::Generic::ICollection<T>, System::Collections::Generic::IEnumerable<T>
public interface ISet<T> : System.Collections.Generic.ICollection<T>, System.Collections.Generic.IEnumerable<T>
type ISet<'T> = interface
    interface ICollection<'T>
    interface seq<'T>
    interface IEnumerable
Public Interface ISet(Of T)

实现

注解

此接口提供用于实现集合的方法,这些方法是具有唯一元素和特定操作的集合。This interface provides methods for implementing sets, which are collections that have unique elements and specific operations. @No__t 0 和 @no__t 1 集合实现此接口。The HashSet<T> and SortedSet<T> collections implement this interface.
