TraceContext.TraceFinished Event

Definition

Generato dall'oggetto TraceContext per esporre i messaggi di traccia dopo la raccolta di tutte le informazioni sulla richiesta.Raised by the TraceContext object to expose trace messages after all request information is gathered.

public:
 event System::Web::TraceContextEventHandler ^ TraceFinished;
public event System.Web.TraceContextEventHandler TraceFinished;
member this.TraceFinished : System.Web.TraceContextEventHandler 
Public Custom Event TraceFinished As TraceContextEventHandler 

Examples

Nell'esempio di codice riportato di seguito viene illustrato come registrare un TraceContextEventHandler per gestire l'evento TraceFinished.The following code example demonstrates how you can register a TraceContextEventHandler to handle the TraceFinished event. In questo esempio, il delegato scorre i messaggi di traccia e li scrive nel flusso di risposta. Tuttavia, è possibile scrivere le stesse informazioni in un database o in un consumer dello strumento di profilatura.In this example, the delegate iterates through the trace messages and writes them to the response stream; however, you could write the same information to a database or a profiling tool consumer.

<%@ Page language="c#" Trace="true" %>
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
    // Register a handler for the TraceFinished event.
    Trace.TraceFinished += new 
        TraceContextEventHandler(this.OnTraceFinished);

    // Write a trace message.
    Trace.Write("Web Forms Infrastructure Methods", "USERMESSAGE: Page_Load complete.");
}
 
// A TraceContextEventHandler for the TraceFinished event.
void OnTraceFinished(object sender, TraceContextEventArgs e)
{
    TraceContextRecord r = null;    
    
    // Iterate through the collection of trace records and write 
    // them to the response stream.
    foreach(object o in e.TraceRecords)
    {
        r = (TraceContextRecord)o;
        Response.Write(String.Format("trace message: {0} <BR>", r.Message));
    }
}       
</script>
<%@ Page language="VB" Trace="true" %>
<script runat="server">
' The Page_Load method.
Private Sub Page_Load(sender As Object, e As EventArgs)

    ' Register a handler for the TraceFinished event.
    AddHandler Trace.TraceFinished, AddressOf OnTraceFinished

    ' Write a trace message.
    Trace.Write("Web Forms Infrastructure Methods", "USERMESSAGE: Page_Load complete.")
End Sub ' Page_Load
 
' A TraceContextEventHandler for the TraceFinished event.
Private Sub OnTraceFinished(sender As Object, e As TraceContextEventArgs)

    Dim r As TraceContextRecord
    Dim o As Object
    
    ' Iterate through the collection of trace records and write 
    ' them to the response stream.

    For Each o In e.TraceRecords
        r = CType(o, TraceContextRecord)
        Response.Write(String.Format("trace message: {0} <BR>", r.Message))
    Next

End Sub ' OnTraceFinished
</script>

Remarks

L'evento TraceFinished viene generato durante la fase di EndRequest dell'elaborazione della richiesta HTTP.The TraceFinished event is raised during the EndRequest stage of HTTP request processing. Viene generato da un oggetto TraceContext dopo la raccolta di tutte le informazioni sulla richiesta, per esporre la raccolta di messaggi di TraceContextRecord a delegati TraceContextEventHandler registrati.It is raised by a TraceContext object after all request information is gathered, to expose the collection of TraceContextRecord messages to registered TraceContextEventHandler delegates.
