EventLogEntry.EntryType Eigenschaft

public:
 property System::Diagnostics::EventLogEntryType EntryType { System::Diagnostics::EventLogEntryType get(); };

public System.Diagnostics.EventLogEntryType EntryType { get; }

member this.EntryType : System.Diagnostics.EventLogEntryType

Public ReadOnly Property EntryType As EventLogEntryType

Eigenschaftswert

Der Ereignistyp, der dem Ereignisprotokolleintrag zugeordnet ist.

Beispiele

Im folgenden Codebeispiel wird die Verwendung des EntryType-Attributs veranschaulicht. In diesem Beispiel verwendet eine switch Anweisung die Konsoleneingabe, um nach Ereignisprotokolleinträgen für das angegebene EntryTypezu suchen. Wenn eine Übereinstimmung gefunden wird, werden Die Informationen zur Protokolleintragsquelle in der Konsole angezeigt.

Hinweise

Alle Ereignistypen verfügen über klar definierte gemeinsame Daten und können optional ereignisspezifische Daten enthalten. Jedes Ereignis hat einen einzelnen Typ, den die Anwendung angibt, wenn sie das Ereignis meldet. Die Ereignisanzeige verwendet den Ereignistyp, um zu bestimmen, welches Symbol in der Listenansicht des Ereignisprotokolls angezeigt werden soll.
