範例

下列程式碼範例示範如何使用 WebEventBufferFlushInfo 類別。 此程式碼範例是針對 類別提供的較大範例的 BufferedWebEventProvider 一部分。

// Processes the messages that have been buffered.
// It is called by the ASP.NET when the flushing of 
// the buffer is required.
public override void ProcessEventFlush(
    WebEventBufferFlushInfo flushInfo)
{

    // Customize event information to be sent to 
    // the Windows Event Viewer Application Log.
    customInfo.AppendLine(
        "SampleEventLogWebEventProvider buffer flush.");

    customInfo.AppendLine(
        string.Format("NotificationType: {0}",
        GetNotificationType(flushInfo)));

    customInfo.AppendLine(
        string.Format("EventsInBuffer: {0}",
        GetEventsInBuffer(flushInfo)));

    customInfo.AppendLine(
        string.Format(
        "EventsDiscardedSinceLastNotification: {0}",
        GetEventsDiscardedSinceLastNotification(flushInfo)));

    // Read each buffered event and send it to the
    // Application Log.
    foreach (WebBaseEvent eventRaised in flushInfo.Events)
        customInfo.AppendLine(eventRaised.ToString());

    // Store the information in the specified file.
    StoreToFile(customInfo, logFilePath, FileMode.Append);
}

    ' Processes the messages that have been buffered.
    ' It is called by the ASP.NET when the flushing of 
    ' the buffer is required according to the parameters 
    ' defined in the <bufferModes> element of the 
    ' <healthMonitoring> configuration section.
    Public Overrides Sub ProcessEventFlush(ByVal flushInfo _
    As WebEventBufferFlushInfo)

        ' Customize event information to be sent to 
        ' the Windows Event Viewer Application Log.
        customInfo.AppendLine( _
        "SampleEventLogWebEventProvider buffer flush.")

        customInfo.AppendLine(String.Format( _
        "NotificationType: {0}", _
        GetNotificationType(flushInfo)))

        customInfo.AppendLine(String.Format( _
        "EventsInBuffer: {0}", _
        GetEventsInBuffer(flushInfo)))

        customInfo.AppendLine(String.Format( _
        "EventsDiscardedSinceLastNotification: {0}", _
GetEventsDiscardedSinceLastNotification( _
flushInfo)))

        ' Read each buffered event and send it to the
        ' Application Log.
        Dim eventRaised As WebBaseEvent
        For Each eventRaised In flushInfo.Events
            customInfo.AppendLine(eventRaised.ToString())
        Next eventRaised
        ' Store the information in the specified file.
        StoreToFile(customInfo, logFilePath, _
        FileMode.Append)
    End Sub

備註

ASP.NET 健康情況監視可讓生產與作業人員管理已部署的 Web 應用程式。 System.Web.Management命名空間包含負責封裝應用程式健康狀態資料的健全狀況事件種類，以及負責處理此資料的提供者類型。 它也包含支援類型，可協助管理健康情況事件。

類別 WebEventBufferFlushInfo 會定義識別緩衝區目前狀態的值。 類別的實例會當做參數傳遞至 ProcessEventFlush 處理已緩衝訊息的方法。 當需要清除緩衝區時，ASP.NET 健康情況監視會呼叫此方法。 這是由組態區段中的 bufferModes 元素 healthMonitoring 所定義的參數所決定。
