Ejemplos

En el ejemplo siguiente se obtiene una lista de registros en el equipo "myServer". A continuación, genera el nombre de cada registro.

#using <System.dll>

using namespace System;

int main()

   while ( myEnum->MoveNext() )
   {
      EventLog^ log = safe_cast<EventLog^>(myEnum->Current);
      Console::WriteLine( "Log: {0}", log->Log );
   }
}

Comentarios

La matriz de objetos es una instantánea de EventLog todos los registros de eventos en el equipo especificado por el machineName parámetro cuando se realiza la llamada a GetEventLogs . Esta no es una colección dinámica, por lo que no refleja la eliminación ni la creación de registros en tiempo real. Debe comprobar que existe un registro en la matriz antes de leerlo o escribir en ella. La matriz suele incluir al menos tres registros: Aplicación, Sistema y Seguridad. Si ha creado registros personalizados en el equipo especificado, también aparecerán en la matriz.

GetEventLogs es un static método, por lo que se puede llamar a en la EventLog propia clase. No es necesario crear una instancia de un EventLog objeto para realizar una llamada al método .

Para recuperar la lista de registros de eventos, debe tener los permisos del Registro adecuados. Estos permisos son idénticos a los necesarios para llamar Exists a y SourceExists.
