IList<T> IList<T> IList<T> IList<T> Interface

定义

表示可按照索引单独访问的一组对象。Represents a collection of objects that can be individually accessed by index.

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

类型参数

T
