StringDictionary.CopyTo-Methode

Kopiert die Werte des Zeichenfolgenwörterbuchs am angegebenen Index in eine eindimensionale Array-Instanz.

Namespace: System.Collections.Specialized
Assembly: System (in system.dll)

Syntax

'Declaration
Public Overridable Sub CopyTo ( _
    array As Array, _
    index As Integer _
)
'Usage
Dim instance As StringDictionary
Dim array As Array
Dim index As Integer

instance.CopyTo(array, index)

public virtual void CopyTo (
    Array array,
    int index
)

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

public void CopyTo (
    Array array, 
    int index
)

public function CopyTo (
    array : Array, 
    index : int
)

Parameter

• array
  Das eindimensionale Array, das das Ziel der aus dem StringDictionary kopierten Werte ist.

• index
  Der Index im Array, bei dem mit dem Kopieren begonnen wird.

Ausnahmen

Hinweise

CopyTo kopiert Objekte, für die eine Typumwandlung in System.Collections.DictionaryEntry durchgeführt werden kann. DictionaryEntry enthält den Schlüssel und den Wert.

Die Elemente, die nach Array kopiert werden, werden in derselben Reihenfolge sortiert, in der der Enumerator das StringDictionary durchläuft.

Diese Methode ist ein O(n)-Vorgang, wobei n der Count ist.

Beispiel

Das folgende Codebeispiel veranschaulicht das Kopieren eines StringDictionary in ein Array.
