EntryWrittenEventArgs-Klasse

Stellt Daten für das EntryWritten-Ereignis bereit.

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

Syntax

'Declaration
Public Class EntryWrittenEventArgs
    Inherits EventArgs
'Usage
Dim instance As EntryWrittenEventArgs

public class EntryWrittenEventArgs : EventArgs

public ref class EntryWrittenEventArgs : public EventArgs

public class EntryWrittenEventArgs extends EventArgs

public class EntryWrittenEventArgs extends EventArgs

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.
