. NET captures global exceptions and logs, Multithreading sends MailTips

In the software, the site will inevitably appear a variety of anomalies, if you have unhandled exceptions in your project and do not want to add an exception everywhere then you can learn from the next scenario

1. Create a new global application file Global.asax This file is used when counting the number of people online

2. There is a Application_Error method in this file that is used by this method, adding the following code to catch the exception

1 //code to run when an unhandled error occurs
2Exception ex = Server.GetLastError ();
3StringBuilder SB =NewStringBuilder ();
4         stringDT = DateTime.Now.ToString ();
5Sb. Append ("------\ r \ n"). Append (DT). Append ("\ r \ n Internal error:"). Append (ex. Innerexception.tostring ())
6. Append ("\ r \ n Stack:"). Append (ex. StackTrace). Append ("\ r \ n Content:"). Append (ex. Message)
7. Append ("\ r \ n Source:"). Append (ex. Source). Append ("\ r \ n");
8Log.setlog (sb.) ToString ());
9Server.ClearError ();
TenServer.Transfer ("error.aspx",false);

3. Create a new record log and automatically send a mail alert class

1 usingSystem;
2 usingSystem.Collections.Generic;
3 usingSystem.Linq;
4 usingsystem.web;
5 usingSystem.IO;
6 usingSystem.Threading;
7 /// <summary>
8 ///Summary description of Log
9 /// </summary>
Ten  Public classLog
 One{
 A      PublicLog ()
 -{
 -         //
 the //TODO: Add constructor logic here
 - //
 -}
 -     Private stringLogbody;
 +      Public stringLogbody
 -{
 +         Get{returnLogbody; }
 A         Set{logbody = value;}
 at}
 -      Public Static voidSetlog (stringStr
 -{
 -         stringPath = HttpContext.Current.Server.MapPath ("Log.log");
 -File.appendalltext (path, str);
 -         //Thread.Sleep (+);
 inLog Log1 =NewLog ();
 -Log1. Logbody = str;
 toThread T =NewThread (NewThreadStart (Log1. SendEmail));
 +T.isbackground =true;
 -T.start ();
 the}

Panax Notoginseng{
 -System.Net.Mail.SmtpClient client =NewSystem.Net.Mail.SmtpClient ();
 theClient. Host ="---";
 +Client. useDefaultCredentials =false;
 AClient. Credentials =NewSystem.Net.NetworkCredential ("---","---");
 theClient. Deliverymethod = System.Net.Mail.SmtpDeliveryMethod.Network;
 +Client. Timeout =9000;
 -System.Net.Mail.MailMessage message =NewSystem.Net.Mail.MailMessage ("---","---");
 $Message. Subject ="---";

Wuyi{
 theClient. Send (message);
 - 
 Wu}
 -         Catch(Exception ex)

4. Create a new error.aspx file for the tip page to catch the exception after the turn
