EventLog Constructor (String)
Initializes a new instance of the EventLog class. Associates the instance with a log on the local computer.
Assembly: System (in System.dll)
This overload sets the Log property to the logName parameter. Before calling WriteEntry, specify the Source property of the EventLog instance. If you are only reading Entries from the log, you can alternatively specify only the Log and MachineName properties.
The following table shows initial property values for an instance of EventLog.
The following example reads entries in the event log, "myNewLog", on the local computer.
