ASP.NET 2.0允许通过代码在TraceFinished事件里来访问每个请求的跟踪信息。TraceFinished事件是由TraceContext对象引发，用于在收集完所有请求信息后公开跟踪消息。可以利用此事件对跟踪信息进行不同的输出。以下代码就是用程序输出跟踪信息。

C#：

<%@ Page Language="C#" %>

protected void Page_Load(object sender, System.EventArgs e)

{

Trace.TraceFinished += new TraceContextEventHandler(OnTraceFinished);

Trace.Write("自定义类别", "自定义跟踪消息");

}

private void OnTraceFinished(object sender, TraceContextEventArgs e)

{

foreach (TraceContextRecord tcr in e.TraceRecords)

{

Response.Write(string.Format("

跟踪类别：{0} 跟踪消息：{1}", tcr.Category, tcr.Message));

}

VB.NET：

<%@ Page Language="VB"%>

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

AddHandler Trace.TraceFinished, AddressOf OnTraceFinished

Trace.Write("自定义类别", "自定义跟踪消息")

End Sub

Private Sub OnTraceFinished(ByVal sender As Object, ByVal e As TraceContextEventArgs)

Dim tcr As TraceContextRecord

For Each tcr In e.TraceRecords

Response.Write(String.Format("

跟踪类别：{0} 跟踪消息：{1}", tcr.Category, tcr.Message))
