我在ASP.NET應用程序中使用日誌記錄應用程序塊（LAB）以及異常處理應用程序塊來記錄任何未處理的異常。我正在使用Global.asax中的Application_Error方法來捕獲這些錯誤。我正在寫入滾動平面文件。這一切都很好。使用日誌記錄應用程序塊編寫調試信息
當我在web.config的appSettings部分設置開關時，我還想使用LAB記錄調試消息。但我不知道如何將這些調試消息發送到不同日誌文件。我真的很感激，如果有人會看我的代碼和web.config的部分，看看是否有任何東西跳出來。謝謝！
這裏是我目前如何嘗試寫入調試記錄器的例子：
private void LogDebugInfo()
{
using (new Tracer("Debugging"))
{
StringBuilder msg = new StringBuilder();
msg.AppendLine("Querystring: " + Request.QueryString.ToString());
foreach (string item in Request.Form)
{
msg.AppendLine("Form item name: " + item + " value: " + Request.Form[item]);
}
HttpFileCollection files = Request.Files;
foreach (string f in files)
{
msg.AppendLine("Posted filename: " + files[f].FileName + " type: " + files[f].ContentType + " length: " + files[f].ContentLength);
}
LogEntry log = new LogEntry();
log.Message = msg.ToString();
Logger.Write(log);
}
}
這裏是web.config中的相關章節：
