一步一步教你实现简单的自定义错误跟踪
一、设计xml,应该包含下面信息:
1、Datetime: 发生错误/异常的日期和时间
2、File name: 发生错误/异常的文件名
3、Class name : 发生错误/异常的类名
4、Methodname: 发生错误/异常的方法名
5、Errormethod : 包含错误代码的函数名字
6、Message :错误/异常的信息
7、Error details: 错误/异常详情
8、IP : 客户端IP地址
9、URL : 发生错误的URL
DemoXML:
DemoXML
xml version="1.0" encoding="utf-8"?>
<errorlog>
<error>
<datetime>datetimedatetime>
<filename>filenamefilename>
<classname>classnameclassname>
<methodname>methodnamemethodname>
<errormethod>errormethoderrormethod>
<messsage>ErrorMessagemesssage>
<errordetails>Details goes hereerrordetails>
<IP>IP adressIP>
<url>URLurl>

errorlog>
<errorlog>
<error>
<datetime>datetimedatetime>
<filename>filenamefilename>
<classname>classnameclassname>
<methodname>methodnamemethodname>
<errormethod>errormethoderrormethod>
<messsage>ErrorMessagemesssage>
<errordetails>Details goes hereerrordetails>
<IP>IP adressIP>
<url>URLurl>
error>
errorlog>
二、设计错误处理类:errorHandler.cs,里面的WriteError方法需要Exception和FileName两个参数:
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();
}
}
}
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();
}
}
}
三、 在Web.config加入:
<appSettings>
<add key="logfilepath" value="~/errorHandling/errorlog.xml"/>
appSettings>
<add key="logfilepath" value="~/errorHandling/errorlog.xml"/>
appSettings>
四、测试:在你的网站中加入两段测试代码
1、在Page_Load:
Page_Load
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
throw new Exception("Custom error");
}
catch (Exception ex)
{
Response.Write(ex.Message);
kirin.errorHandler.WriteError(ex, "Default.aspx.cs");
}
}
}
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
throw new Exception("Custom error");
}
catch (Exception ex)
{
Response.Write(ex.Message);
kirin.errorHandler.WriteError(ex, "Default.aspx.cs");
}
}
}
2、在Application_Error中加入:
void Application_Error(object sender, EventArgs e)
{
code_center.errorHandler.WriteError(Server.GetLastError().GetBaseException(),
"Global.asax");
}
{
code_center.errorHandler.WriteError(Server.GetLastError().GetBaseException(),
"Global.asax");
}
3、Page_Load异常的结果:
errorXML
<error>
<datetime>2010-1-29 9:29:24datetime>
<filename>Default.aspx.vbfilename>
<classname>kirin._Defaultclassname>
<methodname>Page_Loadmethodname>
<errormethod>Page_Loaderrormethod>
<messsage>Custom errormesssage>
<errordetails> 在 kirin._Default.Page_Load(Object sender, EventArgs e) 位置 C:\Demo\kirin_code_center\kirin\Default.aspx.cs:行号 16errordetails>
<IP>127.0.0.1IP>
<url>http://localhost:2192/default.aspxurl>
