Step by step to teach you to implement simple custom error tracking

One, design XML, should contain the following information:

1. DateTime: Date and time when error/exception occurred

2. File name: FileName with error/exception

3, class name: The names of the classes where the error/exception occurred

4. MethodName: The name of the method in which the error/exception occurred

5, Errormethod: The name of the function containing the error code

6, Message: Error/exception information

7. Error Details: Errors/anomalies Particulars

8, IP: Client IP Address

9, url: The URL where the error occurred

Demoxml:

<?xml　version="1.0"　encoding="utf-8"?>
<errorlog>
　　 <error>
　　　　 <datetime>datetime</datetime>
　　　　 <filename>filename</filename>
　　　　 <classname>classname</classname>
　　　　 <methodname>methodname</methodname>
　　　　 <errormethod>errormethod</errormethod>
　　　　 <messsage>ErrorMessage</messsage>
　　　　 <errordetails>Details　goes　here</errordetails>
　　　　 <IP>IP　adress</IP>
　　　　 <url>URL</url>
　　 </error>
</errorlog>

Second, the design error processing class: ErrorHandler.cs, inside the Writeerror method needs exception and filename two parameters:

ErrorHandler.cs

using System;


using System.Collections.Generic;


using System.Text;


using System.Xml;


using System.Reflection;


using System.Diagnostics;


namespace Code_center


{


public class ErrorHandler


　　　　 {


string _strerrormessage, _strdetails, _strclassname, _strmethodname;


datetime _dtoccurancetime = new DateTime ();


Public ErrorHandler ()


　　　　　　　　 {


　　　　　　　　 }


Public ErrorHandler (DateTime time, String className, String methodname,


string errormessage, string details)


　　　　　　　　 {


_dtoccurancetime = time;


_strclassname = ClassName;


_strdetails = details;


_strerrormessage = errormessage;


_strmethodname = methodname;


　　　　　　　　 }


public static void Writeerror (Exception ex)


　　　　　　　　 {


Writeerror (ex, "");


　　　　　　　　 }


public static void Writeerror (Exception ex, string fileName)


　　　　　　　　 {


XmlDocument doc = new XmlDocument ();


string strrootpath =


system.configuration.configurationmanager.appsettings["LogFilePath"]. ToString ();


string xmlpath = System.Web.HttpContext.Current.Server.MapPath (Strrootpath);


Doc. Load (@xmlPath);


XmlNode Newxmlnode, Oldxmlnode;


Oldxmlnode = doc. CHILDNODES[1]. Childnodes[0];


Newxmlnode = Oldxmlnode.clonenode (true);


StackTrace stacktrace = new StackTrace ();


stackframe stackframe = stacktrace.getframe (1);


MethodBase methodbase = Stackframe.getmethod ();


Newxmlnode.childnodes[0]. innertext = DateTime.Now.ToString ();


Newxmlnode.childnodes[1]. innertext = FileName;


newxmlnode.childnodes[2]. innertext = MethodBase.DeclaringType.FullName;


Newxmlnode.childnodes[3]. innertext = Methodbase.name;


Newxmlnode.childnodes[4]. InnerText = ex. Targetsite.name;


Newxmlnode.childnodes[5]. InnerText = ex. message;


Newxmlnode.childnodes[6]. InnerText = ex. StackTrace;


NEWXMLNODE.CHILDNODES[7]. innertext = System.Web.HttpContext.Current.Request.UserHostAddress;


Newxmlnode.childnodes[8]. innertext = System.Web.HttpContext.Current.Request.Url.OriginalString;


Doc. CHILDNODES[1]. AppendChild (Newxmlnode);


Doc. Save (@xmlPath);


Doc. RemoveAll ();


　　　　　　　　 }


　　　　 }
