在ASP.NET代碼里訪問跟蹤信息
ASP.NET 2.0允許通過代碼在TraceFinished事件里來訪問每個請求的跟蹤信息。TraceFinished事件是由TraceContext對象引發，用于在收集完所有請求信息后公開跟蹤消息。可以利用此事件對跟蹤信息進行不同的輸出。以下代碼就是用程序輸出跟蹤信息。
C#:
VB.NET:
C#:
| ＜%@ Page Language="C#" %＞ ＜SCRIPT runat="server"＞ protected void Page_Load(object sender, System.EventArgs e) { Trace.TraceFinished += new TraceContextEventHandler(OnTraceFinished); Trace.Write("自定義類別", "自定義跟蹤消息"); } private void OnTraceFinished(object sender, TraceContextEventArgs e) { foreach (TraceContextRecord tcr in e.TraceRecords) { Response.Write(string.Format(" ＜li＞跟蹤類別:{0} 跟蹤消息:{1}", tcr.Category, tcr.Message)); } } ＜/SCRIPT＞ |
VB.NET:
| ＜%@ Page Language="VB"%＞ ＜SCRIPT runat="server"＞ Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) AddHandler Trace.TraceFinished, AddressOf OnTraceFinished Trace.Write("自定義類別", "自定義跟蹤消息") 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(" ＜li＞跟蹤類別:{0} 跟蹤消息:{1}", tcr.Category, tcr.Message)) Next End Sub ＜/SCRIPT＞ |
