LOG4NET用法(个人比较喜欢的用法)（转）

web.config配置如下：

LOG操作类

[c-sharp] view plaincopy

1. using System;
2. using System.IO;
3. namespace TankAction.SystemLog
4. {
5. /**//// <summary>
6. /// LogHelper的摘要说明。
7. /// </summary>
8. public class LogHelper
9. {
10. private SystemLog()
11. {
12. }
13. public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");
14. public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");
15. public static void SetConfig()
16. {
17. log4net.Config.DOMConfigurator.Configure();
18. }
19. public static void SetConfig(FileInfo configFile)
20. {
21. log4net.Config.DOMConfigurator.Configure(configFile);
22. }
23. public static void WriteLog(string info)
24. {
25. if(loginfo.IsInfoEnabled)
26. {
27. loginfo.Info(info);
28. }
29. }
30. public static void WriteLog(string info,Exception se)
31. {
32. if(logerror.IsErrorEnabled)
33. {
34. logerror.Error(info,se);
35. }
36. }
37. }
38. }

Global.asax.cs文件配置如下：

[c-sharp] view plaincopy

1. protected void Application_Start(Object sender, EventArgs e)
2. {
3. SystemLog.SetConfig();
4. }
5. protected void Application_Error(Object sender, EventArgs e)
6. {
7. Exception objExp = HttpContext.Current.Server.GetLastError();
8. LogHelper.WriteLog("/r/n客户机IP:"+ Request.UserHostAddress +"/r/n错误地址:"+ Request.Url +"/r/n异常信息:"+ Server.GetLastError().Message,objExp);
9. }

eg:
   try
   {}
   catch(Exception ex)
   {
       LogHelper.WriteLog("ErrorInfo"ex);
   }
