ArraySegment<T>.IList<T>.Item[Int32] 屬性

定義

命名空間:

System

組件:

System.Runtime.dll

來源:

ArraySegment.cs

在指定的索引位置上取得或設定項目。

property T System::Collections::Generic::IList<T>::Item[int] { T get(int index); void set(int index, T value); };

T System.Collections.Generic.IList<T>.Item[int index] { get; set; }

member this.System.Collections.Generic.IList<T>.Item(int) : 'T with get, set

 Property Item(index As Integer) As T Implements IList(Of T).Item

參數

index

Int32

要取得或設定的以零為起始元素索引。

屬性值

T

在指定索引上的項目。

實作

Item[Int32]

例外狀況

ArgumentOutOfRangeException

index 不是 ArraySegment<T> 中的有效索引。

NotSupportedException

已設定該屬性，陣列區段是唯讀的。

備註

這個成員是明確介面成員實作， 只有當實例轉換成 IList<T> 介面時 ArraySegment<T> ，才能使用它，如下列範例所示。
