效果图:
1:第一步创建SQL表结构
-
CREATE TABLE [dbo].[LogDetails] (
-
[LogID] int NOT NULL IDENTITY(1,1) ,
-
[LogDate] datetime NOT NULL ,
-
[LogThread] nvarchar(100) NOT NULL ,
-
[LogLevel] nvarchar(200) NOT NULL ,
-
[LogLogger] nvarchar(500) NOT NULL ,
-
[LogMessage] nvarchar(3000) NOT NULL ,
-
[LogActionClick] nvarchar(4000) NULL ,
-
[UserName] nvarchar(30) NULL ,
-
[UserIP] varchar(20) NULL
-
)
2:创建项目然后下载log4net.dll 在项目中添加引用http://logging.apache.org/log4net/download_log4net.cgi下载Binaries 下面的
3:创建 log4net.config
-
<?xml version="1.0" encoding="utf-8" ?>
-
-
<log4net debug="false">
-
<!-- name属性指定其名称,type则是log4net.Appender命名空间的一个类的名称,意思是,指定使用哪种介质-->

</layout>
-
</parameter>
-
</appender>
-
<!-- setup the root category, add the appenders and set the default level -->
-
<root>
-
<level value="Warn"/><!-- 定义记录的日志级别-->

-
</layout>
-
</appender>
-
-
-
-
-
</log4net>
4:在Web.config 里面加 configSections 节点 (CS可直接写在app.config里面,或者都写在一个config里面)
-
<configuration>
-
<strong> <span style="color:#FF0000;"> <configSections>
-
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
-
</configSections>
-
<log4net configSource="log4net.config"/></span></strong>
-
-
<system.web>
-
<compilation debug="true" targetFramework="4.5" />
-
<httpRuntime targetFramework="4.5" />
-
</system.web>
-
-
</configuration>
5:Properties 属性下面的AssemblyInfo.cs 追加 必须有这个,否则写入不到数据库中
-
//[assembly: log4net.Config.XmlConfigurator(Watch = true)]
-
//注意: ConfigFile 可以指定相对路径 和 绝对路径。 eg: /log/xxxx.log 或者 d://log//xxxx.log
-
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]
6:添加 Global.asax
然后在Application_Start 追加 读取配置程序文件
-
protected void Application_Start(object sender, EventArgs e)
-
{
-
//应用程序启动时,自动加载配置log4Net
-
XmlConfigurator.Configure();
-
}
7:创建自定义类 LogPublicClass.cs,为了方便写入数据库中 自定义的一些信息
-
using log4net.Layout;
-
using log4net.Layout.Pattern;
-
using System;
-
using System.Collections.Generic;
-
using System.Linq;
-
using System.Reflection;
-
using System.Web;
-
-
namespace Log4NetApply
-
{
-
/// <summary>
-
/// 包含了所有的自定字段属性
-
/// </summary>
-
public class LogContent
-
{
-
public LogContent(string macAddress, string computerName, string actionsclick, string description)
-
{
-
UserIP = macAddress;
-
UserName = computerName;
-
ActionsClick = actionsclick;
-
Message = description;
-
}
-
-
/// <summary>
-
/// 访问IP
-
/// </summary>
-
public string UserIP { get; set; }
-
-
/// <summary>
-
/// 系统登陆用户
-
/// </summary>
-
public string UserName { get; set; }
-
-
/// <summary>
-
/// 动作事件
-
/// </summary>
-
public string ActionsClick { get; set; }
-
-
/// <summary>
-
/// 日志描述信息
-
/// </summary>
-
public string Message { get; set; }
-
-
-
}
-
public class MyLayout : PatternLayout
-
{
-
public MyLayout()
-
{
-
this.AddConverter("property", typeof(LogInfoPatternConverter));
-
}
-
}
-
-
public class LogInfoPatternConverter : PatternLayoutConverter
-
{
-
-
protected override void Convert(System.IO.TextWriter writer, log4net.Core.LoggingEvent loggingEvent)
-
{
-
if (Option != null)
-
{
-
// Write the value for the specified key
-
WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
-
}
-
else
-
{
-
// Write all the key value pairs
-
WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
-
}
-
}
-
/// <summary>
-
/// 通过反射获取传入的日志对象的某个属性的值
-
/// </summary>
-
/// <param name="property"></param>
-
/// <returns></returns>
-
-
private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent)
-
{
-
object propertyValue = string.Empty;
-
PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property);
-
if (propertyInfo != null)
-
propertyValue = propertyInfo.GetValue(loggingEvent.MessageObject, null);
-
return propertyValue;
-
}
-
}
-
}
8:示例使用
-
try
-
{
-
log.Info(new LogContent("127.0.0.1", "111111", "登陆系统", "登陆成功"));
-
var ss = 1 - int.Parse("sss");
-
}
-
catch(Exception ex)
-
{
-
log.Error(new LogContent("127.0.0.1", "111111", "登陆系统", ex.Message+":"+ex.StackTrace));
-
}
