Exemples

L’exemple suivant illustre le EntryWrittenEventArgs constructeur. Il crée un objet personnalisé EventLog et y écrit une entrée. Ensuite, il crée un EntryWrittenEventArgs objet à l’aide de la première entrée dans le personnalisé EventLog. Cet objet est utilisé pour notifier un message.

#using <System.dll>

using namespace System;
using namespace System::Diagnostics;

void MyOnEntry( Object^ source, EntryWrittenEventArgs^ e )
{
   if ( !e->Entry )
      Console::WriteLine( "A new entry is written in MyNewLog." );
}

int main()
{
   try
   {
      EventLog^ myNewLog = gcnew EventLog;
      myNewLog->Log = "MyNewLog";
      myNewLog->Source = "MySource";
      
      // Create the source if it does not exist already.
      if (  !EventLog::SourceExists( "MySource" ) )
      {
         EventLog::CreateEventSource( "MySource", "MyNewLog" );
         Console::WriteLine( "CreatingEventSource" );
      }
      
      // Write an entry to the EventLog.
      myNewLog->WriteEntry( "The Latest entry in the Event Log" );
      int myEntries = myNewLog->Entries->Count;
      EventLogEntry^ entry = myNewLog->Entries[ myEntries - 1 ];
      EntryWrittenEventArgs^ myEntryEventArgs = gcnew EntryWrittenEventArgs;
      MyOnEntry( myNewLog, myEntryEventArgs );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception Raised{0}", e->Message );
   }
}

Méthodes

Equals(Object)	Détermine si l'objet spécifié est égal à l'objet actuel. (Hérité de Object)
GetHashCode()	Fait office de fonction de hachage par défaut. (Hérité de Object)
GetType()	Obtient le Type de l'instance actuelle. (Hérité de Object)
MemberwiseClone()	Crée une copie superficielle du Object actuel. (Hérité de Object)
ToString()	Retourne une chaîne qui représente l'objet actuel. (Hérité de Object)
