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。
Public Overridable Sub SetRange( _
ByVal index As Integer, _ ByVal c As ICollection _)
[C#]
public virtual void SetRange(intindex,ICollectionc);
[C++]
public: virtual void SetRange(intindex,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 (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 が読み取り専用です。 |
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。
使用例
ArrayList 内の要素の範囲を設定および取得する方法の例を次に示します。
