構文

Visual Basic (宣言)

Public Sub CopyTo ( _
    array As XmlAttribute(), _
    index As Integer _
)

Visual Basic (使用法)

Dim instance As XmlAttributeCollection
Dim array As XmlAttribute()
Dim index As Integer

instance.CopyTo(array, index)

public void CopyTo (
    XmlAttribute[] array,
    int index
)

C++

public:
void CopyTo (
    array<XmlAttribute^>^ array, 
    int index
)

public void CopyTo (
    XmlAttribute[] array, 
    int index
)

JScript

public function CopyTo (
    array : XmlAttribute[], 
    index : int
)

パラメータ

array: このコレクションからコピーされたオブジェクトのコピー先の配列。

index: 配列内のコピー開始位置を示すインデックス。

解説

このメソッドは、DOM (Document Object Model) に対する Microsoft 拡張機能です。

使用例

CopyTo を使用して、コレクション内のすべての属性を配列にコピーする例を次に示します。
