Copies the property values of an EventLog component that are required at installation time for an event log.
Namespace: System.Diagnostics Assembly: System.Configuration.Install (in system.configuration.install.dll)
The component specified by the component parameter must be an EventLog; otherwise, an exception is thrown.
Typically, you do not call the methods of the EventLogInstaller from within your code; they are generally called only by the Installer Tool (Installutil.exe). CopyFromComponent is used by Installutil.exe to set the property values for the EventLogInstaller to the values of an existing EventLog.
If the Log of the EventLog that is passed in is an empty string (""), you must set the Log property to a valid value before the installer executes.
