List<T>.Reverse List<T>.Reverse List<T>.Reverse List<T>.Reverse Method

定義

List<T> またはその一部の要素の順序を反転させます。Reverses the order of the elements in the List<T> or a portion of it.

オーバーロード

Reverse() Reverse() Reverse() Reverse()

List<T> 全体の要素の順序を反転させます。Reverses the order of the elements in the entire List<T>.

Reverse(Int32, Int32) Reverse(Int32, Int32) Reverse(Int32, Int32) Reverse(Int32, Int32)

指定した範囲の要素の順序を反転させます。Reverses the order of the elements in the specified range.

Reverse() Reverse() Reverse() Reverse()

List<T> 全体の要素の順序を反転させます。Reverses the order of the elements in the entire List<T>.

public:
 void Reverse();
public void Reverse ();
member this.Reverse : unit -> unit
Public Sub Reverse ()

次の例の両方のオーバー ロード、Reverseメソッド。The following example demonstrates both overloads of the Reverse method. 例は、作成、List<T>の文字列し、6 つの文字列を追加します。The example creates a List<T> of strings and adds six strings. Reverse() 、リストを反転させるメソッド オーバー ロードを使用し、Reverse(Int32, Int32)要素 1 で始まると、4 つの要素を含む、リストの中央を反転させるメソッド オーバー ロードを使用します。The Reverse() method overload is used to reverse the list, and then the Reverse(Int32, Int32) method overload is used to reverse the middle of the list, beginning with element 1 and encompassing four elements.
