EventLog Constructor (String)

Initializes a new instance of the EventLog class. Associates the instance with a log on the local computer.

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

public function EventLog(
	logName : String
)

Parameters

logName
Type: System.String

The name of the log on the local computer.

ExceptionCondition
ArgumentNullException

The log name is a null reference (Nothing in Visual Basic).

ArgumentException

The log name is invalid.

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.

NoteNote:

If you do not specify a MachineName, the local computer (".") is assumed. This overload of the constructor specifies the Log property, but you can change this before reading the Entries property.

If the source you specify in the Source property is unique from other sources on the computer, a subsequent call to WriteEntry creates a log with the specified name, if it does not already exist.

The following table shows initial property values for an instance of EventLog.

Property

Initial Value

Source

An empty string ("").

Log

The logName parameter.

MachineName

The local computer (".").

The following example reads entries in the event log, "myNewLog", on the local computer.
