Exemplos

O exemplo a seguir demonstra o EntryWrittenEventArgs construtor. Ele cria um objeto personalizado EventLog e grava uma entrada nele. Em seguida, ele cria um EntryWrittenEventArgs objeto usando a primeira entrada no personalizado EventLog. Esse objeto é usado para notificar uma mensagem.

#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 );
   }
}

Construtores

EntryWrittenEventArgs()	Inicializa uma nova instância da classe EntryWrittenEventArgs.
EntryWrittenEventArgs(EventLogEntry)	Inicializa uma nova instância da classe EntryWrittenEventArgs com a entrada de log de eventos especificado.

Propriedades

Entry

Obtém a entrada de log de eventos que foram gravados no log.

Métodos

Equals(Object)	Determina se o objeto especificado é igual ao objeto atual. (Herdado de Object)
GetHashCode()	Serve como a função de hash padrão. (Herdado de Object)
GetType()	Obtém o Type da instância atual. (Herdado de Object)
MemberwiseClone()	Cria uma cópia superficial do Object atual. (Herdado de Object)
ToString()	Retorna uma cadeia de caracteres que representa o objeto atual. (Herdado de Object)
