EventLogEntryCollection.CopyTo(EventLogEntry[], Int32) Metodo

Definizione

Copia gli elementi dell'insieme EventLogEntryCollection in una matrice di istanze EventLogEntry, cominciando da un particolare indice di matrice.Copies the elements of the EventLogEntryCollection to an array of EventLogEntry instances, starting at a particular array index.

public:
 void CopyTo(cli::array <System::Diagnostics::EventLogEntry ^> ^ eventLogEntries, int index);
public void CopyTo (System.Diagnostics.EventLogEntry[] eventLogEntries, int index);
member this.CopyTo : System.Diagnostics.EventLogEntry[] * int -> unit
Public Sub CopyTo (eventLogEntries As EventLogEntry(), index As Integer)

Parametri

entries
EventLogEntry[]

Matrice unidimensionale delle istanze EventLogEntry, ovvero la destinazione degli elementi copiati dall'insieme.The one-dimensional array of EventLogEntry instances that is the destination of the elements copied from the collection. La matrice deve avere un'indicizzazione in base zero.The array must have zero-based indexing.

index
Int32

Indice in base zero nella matrice in corrispondenza del quale ha inizio la copia.The zero-based index in the array at which copying begins.

Esempi

Nell'esempio seguente viene creata EventLogEntry una matrice e viene CopyTo utilizzato il metodo per copiarvi il EventLogEntryCollection contenuto di un oggetto.The following example creates an EventLogEntry array and uses the CopyTo method to copy the contents of an EventLogEntryCollection into it.


// Copy the EventLog entries to Array of type EventLogEntry.
EventLogEntry[] myEventLogEntryArray =
   new EventLogEntry[myEventLogEntryCollection.Count];
myEventLogEntryCollection.CopyTo(myEventLogEntryArray, 0);
IEnumerator myEnumerator = myEventLogEntryArray.GetEnumerator();
while (myEnumerator.MoveNext())
{
    EventLogEntry myEventLogEntry = (EventLogEntry)myEnumerator.Current;
    Console.WriteLine("The LocalTime the Event is generated is "
       + myEventLogEntry.TimeGenerated);
}
' Copy the EventLog entries to Array of type EventLogEntry.
Dim myEventLogEntryArray(myEventLogEntryCollection.Count-1) As EventLogEntry
myEventLogEntryCollection.CopyTo(myEventLogEntryArray, 0)
Dim myEnumerator As IEnumerator = myEventLogEntryArray.GetEnumerator()
While myEnumerator.MoveNext()
   Dim myEventLogEntry As EventLogEntry = CType(myEnumerator.Current, EventLogEntry)
   Console.WriteLine("The LocalTime the Event is generated is " + _
                        myEventLogEntry.TimeGenerated)
End While

Commenti

Poiché le nuove voci vengono aggiunte all'elenco esistente, l'esecuzione nella raccolta consente di accedere alle voci create dopo la EventLogEntryCollectioncreazione iniziale di.Because new entries are appended to the existing list, stepping through the collection enables you to access the entries that were created after you originally created the EventLogEntryCollection. Una matrice di EventLogEntry istanze è fissa nel momento in cui viene creata un'istanza.An array of EventLogEntry instances is fixed at the time it is instantiated. Non è pertanto possibile leggere nuove voci utilizzando la matrice restituita dal CopyTo metodo.Therefore, you cannot read new entries by using the array that is returned by the CopyTo method.
