Exemplos

O exemplo de código a seguir grava uma entrada de evento informativo e, em seguida, reutiliza a EventInstance gravação de uma entrada para um evento de aviso em um log de eventos existente. O texto da mensagem de evento é especificado usando um identificador de recurso em um arquivo de recurso de mensagem. O exemplo de código pressupõe que o arquivo de recurso de mensagem correspondente foi registrado para a origem.


// Ensure that the source has already been registered using
// EventLogInstaller or EventLog.CreateEventSource.

string sourceName = "SampleApplicationSource";
if(EventLog.SourceExists(sourceName))
{
    // Define an informational event with no category.
    // The message identifier corresponds to the message text in the
    // message resource file defined for the source.
    EventInstance myEvent = new EventInstance(UpdateCycleCompleteMsgId, 0);

    // Write the event to the event log using the registered source.
    EventLog.WriteEvent(sourceName, myEvent);

    // Reuse the event data instance for another event entry.
    // Set the entry category and message identifiers for
    // the appropriate resource identifiers in the resource files
    // for the registered source.  Set the event type to Warning.

    myEvent.CategoryId = RefreshCategoryMsgId;
    myEvent.EntryType = EventLogEntryType.Warning;
    myEvent.InstanceId = ServerConnectionDownMsgId;

    // Write the event to the event log using the registered source.
    // Insert the machine name into the event message text.
    EventLog.WriteEvent(sourceName, myEvent, Environment.MachineName);
}
else
{
    Console.WriteLine("Warning - event source {0} not registered",
        sourceName);
}

' Ensure that the source has already been registered using
' EventLogInstaller or EventLog.CreateEventSource.
Dim sourceName as String = "SampleApplicationSource"
If EventLog.SourceExists(sourceName)
    
    ' Define an informational event with no category.
    ' The message identifier corresponds to the message text in the
    ' message resource file defined for the source.
    Dim myEvent As EventInstance = New EventInstance(UpdateCycleCompleteMsgId, 0)
    ' Write the event to the event log using the registered source.
    EventLog.WriteEvent(sourceName, myEvent)

    ' Reuse the event data instance for another event entry.
    ' Set the entry category and message identifiers for
    ' the appropriate resource identifiers in the resource files
    ' for the registered source.  Set the event type to Warning.

    myEvent.CategoryId = RefreshCategoryMsgId
    myEvent.EntryType = EventLogEntryType.Warning
    myEvent.InstanceId = ServerConnectionDownMsgId

    ' Write the event to the event log using the registered source.
    ' Insert the machine name into the event message text.
    EventLog.WriteEvent(sourceName, myEvent, Environment.MachineName)

Else 
    Console.WriteLine("Warning - event source {0} not registered", _
        sourceName)
End If

O exemplo de código usa o arquivo de texto de mensagem a seguir, integrado à biblioteca de recursos EventLogMsgs.dll. Um arquivo de texto de mensagem é a origem da qual o arquivo de recurso de mensagem é criado. O arquivo de texto da mensagem define os identificadores de recurso e o texto para as cadeias de caracteres de categoria, mensagem de evento e inserção de parâmetro.
