Stack.CopyTo(Array, Int32) メソッド

定義

名前空間:

System.Collections

アセンブリ:

System.Collections.NonGeneric.dll

ソース:

Stack.cs

Stack を既存の 1 次元 Array に、指定の配列インデックスを開始位置としてコピーします。

public:
 virtual void CopyTo(Array ^ array, int index);

public virtual void CopyTo (Array array, int index);

abstract member CopyTo : Array * int -> unit
override this.CopyTo : Array * int -> unit

Public Overridable Sub CopyTo (array As Array, index As Integer)

パラメーター

array

Array

Array から要素がコピーされる 1 次元の Stack。 Array には、0 から始まるインデックス番号が必要です。

index

Int32

コピーの開始位置とする array のインデックス (0 から始まる)。

実装

CopyTo(Array, Int32)

例外

ArgumentNullException

array が nullです。

ArgumentOutOfRangeException

index が 0 未満です。

ArgumentException

array が多次元です。

または

コピー元の Stack の要素数が、コピー先 array の index から最後までの使用可能領域を超えています。

InvalidCastException

コピー元の Stack の型をコピー先の array の型に自動的にキャストすることはできません。

例

次の例は、 を 1 次元配列にコピー Stack する方法を示しています。

   // Displays the values of the target Array.
   PrintValues( myTargetArray, ' ' );
