EntryWrittenEventArgs-Konstruktor (EventLogEntry)

Initialisiert eine neue Instanz der EntryWrittenEventArgs-Klasse mit dem angegebenen Eintrag im Ereignisprotokoll.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

Syntax

'Declaration
Public Sub New ( _
    entry As EventLogEntry _
)
'Usage
Dim entry As EventLogEntry

Dim instance As New EntryWrittenEventArgs(entry)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

public:
EntryWrittenEventArgs (
    EventLogEntry^ entry
)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

public function EntryWrittenEventArgs (
    entry : EventLogEntry
)

Parameter

• entry
  Ein EventLogEntry, der den geschriebenen Eintrag darstellt.

Beispiel

Im folgenden Beispiel wird der EntryWrittenEventArgs-Konstruktor veranschaulicht. Es wird ein benutzerdefiniertes EventLog-Objekt erstellt und ein Eintrag in dieses geschrieben. Anschließend wird ein EntryWrittenEventArgs-Objekt unter Verwendung des ersten Eintrags im benutzerdefinierten EventLog erstellt. Dieses Objekt wird zum Benachrichtigen einer Meldung verwendet.
