Array.Sort メソッド

2008-03-28

1 次元 Array オブジェクト内の要素を並べ替えます。

オーバーロードの一覧

Array の各要素によって実装された IComparable インターフェイスを使用して、1 次元 Array 全体の要素を並べ替えます。

.NET Compact Framework でもサポート。

[C#] public static void Sort(Array);

[C++] public: static void Sort(Array*);

[JScript] public static function Sort(Array);

2 つの 1 次元 Array オブジェクト (一方のオブジェクトがキーを格納し、他方のオブジェクトがそれらに対応する項目を格納する) を、最初の Array 内のキーに基づき、各キーによって実装された IComparable インターフェイスを使用して並べ替えます。

[Visual Basic] Overloads Public Shared Sub Sort(Array, Array)

[C#] public static void Sort(Array, Array);

[C++] public: static void Sort(Array*, Array*);

[C#] public static void Sort(Array, IComparer);

[C++] public: static void Sort(Array*, IComparer*);

[JScript] public static function Sort(Array, IComparer);

2 つの 1 次元 Array オブジェクト (一方のオブジェクトがキーを格納し、他方のオブジェクトがそれらに対応する項目を格納する) を、最初の Array 内のキーに基づき、指定した IComparer インターフェイスを使用して並べ替えます。

[Visual Basic] Overloads Public Shared Sub Sort(Array, Array, IComparer)

[C#] public static void Sort(Array, Array, IComparer);

[C++] public: static void Sort(Array*, Array*, IComparer*);

[JScript] public static function Sort(Array, Array, IComparer);

Array の各要素によって実装された IComparable インターフェイスを使用して、1 次元 Array の範囲内の要素を並べ替えます。

[Visual Basic] Overloads Public Shared Sub Sort(Array, Integer, Integer)

[C#] public static void Sort(Array, int, int);

[C++] public: static void Sort(Array*, int, int);

[JScript] public static function Sort(Array, int, int);

[JScript] public static function Sort(Array, Array, int, int);

1 次元 Array の範囲内の要素を、指定した IComparer インターフェイスを使用して並べ替えます。

.NET Compact Framework でもサポート。

[Visual Basic] Overloads Public Shared Sub Sort(Array, Integer, Integer, IComparer)

[C#] public static void Sort(Array, int, int, IComparer);

[C++] public: static void Sort(Array*, int, int, IComparer*);

[JScript] public static function Sort(Array, int, int, IComparer);

.NET Compact Framework でもサポート。

[Visual Basic] Overloads Public Shared Sub Sort(Array, Array, Integer, Integer, IComparer)

[C++] public: static void Sort(Array*, Array*, int, int, IComparer*);

[JScript] public static function Sort(Array, Array, int, int, IComparer);

使用例

[Visual Basic, C#, C++] キーと値をそれぞれ含む 2 つの関連付けられた配列を並べ替える方法を次の例に示します。既定の比較演算子と並べ替え順序を反転するカスタム比較演算子を使用して並べ替えを行います。現在の CultureInfo によって結果が異なることがあります。

[Visual Basic, C#, C++] メモここでは、Sort のオーバーロード形式のうちの 1 つだけについて、使用例を示します。その他の例については、各オーバーロード形式のトピックを参照してください。
