Beispiele

Im folgenden Beispiel wird eine Implementierung der Send-Methode veranschaulicht. In dieser Implementierung werden Verfolgungsmeldungen nach Beendigung eines Workflows in das Ereignisprotokoll geschrieben. Dieses Beispiel stammt aus dem Termination Tracking Service SDK-Beispiel. Weitere Informationen finden Sie im Beispiel zum Beenden des Nachverfolgungsdiensts.

/// <summary>
/// Receives tracking events.  Instance terminated events are written to the event log.
/// </summary>
protected override void Send(TrackingRecord record)
{
    WorkflowTrackingRecord instanceTrackingRecord = record as WorkflowTrackingRecord;

    if ((null == instanceTrackingRecord) || (TrackingWorkflowEvent.Terminated != instanceTrackingRecord.TrackingWorkflowEvent))
        return;

    // Create an EventLog instance and assign its source.
    EventLog log = new EventLog();
    log.Source = sourceValue;

    // Write an informational entry to the event log.
    TrackingWorkflowTerminatedEventArgs terminatedEventArgs = instanceTrackingRecord.EventArgs as TrackingWorkflowTerminatedEventArgs;

    StringBuilder message = new StringBuilder(512);
    message.AppendLine(string.Format(System.Globalization.CultureInfo.InvariantCulture, "Workflow instance {0} has been terminated.", parametersValue.InstanceId.ToString()));
    message.AppendLine();

    if (null != terminatedEventArgs.Exception)
        message.AppendLine(terminatedEventArgs.Exception.ToString());

    log.WriteEntry(message.ToString(), EventLogEntryType.Warning);
}

    Dim Message As New StringBuilder(512)
    Message.AppendLine(String.Format(System.Globalization.CultureInfo.InvariantCulture, "Workflow instance 0} has been terminated.", parametersValue.InstanceId.ToString()))
    Message.AppendLine()

Hinweise

Die Laufzeitverfolgungsinfrastruktur ruft Send auf, um einen TrackingRecord über den TrackingChannel zu senden, wenn sie mit einem Verfolgungspunkt in einem TrackingProfile übereinstimmt. Sie können die über einen TrackingChannel gesendeten Verfolgungsinformationen den Anforderungen Ihrer Anwendung entsprechend beliebig verarbeiten.
