SortedList.GetKeyList-Methode

Ruft die Schlüssel in SortedList ab.

Namespace: System.Collections
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Overridable Function GetKeyList As IList
'Usage
Dim instance As SortedList
Dim returnValue As IList

returnValue = instance.GetKeyList

public virtual IList GetKeyList ()

public:
virtual IList^ GetKeyList ()

public IList GetKeyList ()

public function GetKeyList () : IList

Rückgabewert

Eine IList, die die Schlüssel in SortedList enthält.

Hinweise

Die zurückgegebene IList ist eine schreibgeschützte Ansicht der Schlüssel von SortedList. Änderungen, die an der zugrunde liegenden SortedList vorgenommen wurden, werden sofort in IList wiedergegeben.

Die Elemente der zurückgegebenen IList sind in derselben Reihenfolge sortiert wie die Schlüssel in SortedList.

Ähnlich Keys, wobei jedoch eine IList anstelle einer ICollection zurückgegeben wird.

Diese Methode ist eine O(1)-Operation.

Beispiel

Im folgenden Beispiel wird gezeigt, wie ein oder alle Schlüssel bzw. Werte in SortedList abgerufen werden.
