Hinweise

Dieser Konstruktor legt die Log Eigenschaft auf den logName Parameter, die MachineName Eigenschaft auf den machineName Parameter und die Source Eigenschaft auf den source Parameter fest. Die Source Eigenschaft ist beim Schreiben in ein Ereignisprotokoll erforderlich. Wenn Sie jedoch nur aus einem Ereignisprotokoll lesen, sind nur die und MachineName die Log Eigenschaften erforderlich (sofern das Ereignisprotokoll auf dem Server bereits eine Quelle zugeordnet ist). Wenn Sie nur aus dem Ereignisprotokoll lesen, reicht möglicherweise eine andere Überladung des Konstruktors aus.

In der folgenden Tabelle sind die anfänglichen Eigenschaftswerte für eine Instanz von EventLog.
