EventLog.Exists Method (String, String)

public static bool Exists (
	string logName,
	string machineName
)

public static boolean Exists (
	String logName, 
	String machineName
)

public static function Exists (
	logName : String, 
	machineName : String
) : boolean

Not applicable.

Parameters

logName

The log for which to search. Possible values include: Application, Security, System, other application-specific logs (such as those associated with Active Directory), or any custom log on the computer.

machineName

The name of the computer on which to search for the log, or "." for the local computer.

Return Value

Use this method to determine if a log exists on a remote computer. If you want to determine whether a source exists on a remote computer, use SourceExists.

Because this method accesses the registry, you must have the appropriate registry permissions on the specified computer; otherwise, the query returns false.

Because you cannot give a new log the name of an existing log on the same computer, use this method before creating a new log to determine if one with the specified logName already exists on the server specified by the machineName parameter. The logName and machineName parameters are not case sensitive.

Exists is a static method, so it can be called on the class itself. It is not necessary to create a new instance of EventLog to call Exists.
