Public Custom Event TraceFinished As TraceContextEventHandler
Jenis Acara
Contoh
Contoh kode berikut menunjukkan bagaimana Anda dapat mendaftarkan TraceContextEventHandler untuk menangani TraceFinished peristiwa. Dalam contoh ini, delegasi melakukan iterasi melalui pesan pelacakan dan menulisnya ke aliran respons; namun, Anda dapat menulis informasi yang sama ke database atau konsumen alat pembuatan profil.
<%@ 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>
Keterangan
Peristiwa TraceFinished dinaikkan selama EndRequest
tahap pemrosesan permintaan HTTP. Ini dimunculkan oleh TraceContext objek setelah semua informasi permintaan dikumpulkan, untuk mengekspos kumpulan TraceContextRecord pesan ke delegasi terdaftar TraceContextEventHandler .
