利用Global.asax的Application_Error實現錯誤記錄 

錯誤日志 

復制代碼代碼如下:

void Application_Error(object sender, EventArgs e) 
{ 
// 在出現未處理的錯誤時運行的代碼 
Exception ex = Server.GetLastError().GetBaseException(); 
StringBuilder str = new StringBuilder(); 
str.Append("\r\n" + DateTime.Now.ToString("yyyy.MM.dd HH:mm:ss")); 
str.Append("\r\n.客戶信息："); 


string ip = ""; 
if (Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR") != null) 
{ 
ip = Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR").ToString().Trim(); 
} 
else 
{ 
ip = Request.ServerVariables.Get("Remote_Addr").ToString().Trim(); 
} 
str.Append("\r\n\tIp:" + ip); 
str.Append("\r\n\t瀏覽器:" + Request.Browser.Browser.ToString()); 
str.Append("\r\n\t瀏覽器版本:" + Request.Browser.MajorVersion.ToString()); 
str.Append("\r\n\t操作系統:" + Request.Browser.Platform.ToString()); 
str.Append("\r\n.錯誤信息："); 
str.Append("\r\n\t頁面：" + Request.Url.ToString()); 
str.Append("\r\n\t錯誤信息：" + ex.Message); 
str.Append("\r\n\t錯誤源：" + ex.Source); 
str.Append("\r\n\t異常方法：" + ex.TargetSite); 
str.Append("\r\n\t堆棧信息：" + ex.StackTrace); 
str.Append("\r\n--------------------------------------------------------------------------------------------------"); 
//創建路徑 
string upLoadPath = Server.MapPath("~/log/"); 
if (!System.IO.Directory.Exists(upLoadPath)) 
{ 
System.IO.Directory.CreateDirectory(upLoadPath); 
} 
//創建文件 寫入錯誤 
System.IO.File.AppendAllText(upLoadPath + DateTime.Now.ToString("yyyy.MM.dd") + ".log", str.ToString(), System.Text.Encoding.UTF8); 
//處理完及時清理異常 
Server.ClearError(); 
//跳轉至出錯頁面 
Response.Redirect("~/error.html"); 
}
