ArrayList.SetRange メソッド

.NET Framework クラス ライブラリ リファレンス

ArrayList.SetRange メソッド

コレクションの要素を ArrayList 内の要素の範囲にコピーします。

名前空間: System.Collections
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Overridable Sub SetRange
 ( _
    index As Integer, _
    c As ICollection _
)

Visual Basic (使用法)

Dim instance As ArrayList
Dim index As Integer
Dim c As ICollection

instance.SetRange(index, c)

C#

public virtual void SetRange (
    int index,
    ICollection c
)

C++

public:
virtual void SetRange (
    int index, 
    ICollection^ c
)

J#

public void SetRange (
    int index, 
    ICollection c
)

JScript

public function SetRange (
    index : int, 
    c : ICollection
)

パラメータ

index

c の要素のコピーを開始する位置を示す、0 から始まる ArrayList インデックス。

c

要素を ArrayList にコピーする ICollection。コレクション自体を null 参照 (Visual Basic では Nothing) にすることはできませんが、コレクションに格納する要素は null 参照 (Visual Basic では Nothing) であってもかまいません。

例外

例外の種類	条件
ArgumentOutOfRangeException	index が 0 未満です。 または index と、c 内の要素の数を合計した値が、Count よりも大きい値です。
ArgumentNullException	c が null 参照 (Visual Basic では Nothing) です。
NotSupportedException	ArrayList は読み取り専用です。

解説

ArrayList は、null 参照 (Visual Basic では Nothing) を有効な値として受け取り、要素の重複を許可します。

ICollection 内の要素の順序は、ArrayList に保持されます。

このメソッドは O(n) 操作です。ここで、n は Count です。

使用例

ArrayList の一連の要素を設定または取得する方法を次のコード例に示します。
