log4net-1.2.13-bin-newkey.zip(編譯好的dll文件)

第1步，新建全局配置文件log4net.config,以每天日期格式分割日志文件

<?xml version="1.0"?> <configuration><configSections><section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /></configSections><log4net><!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL --><!-- Set root logger level to ERROR and its appenders --><root><level value="ALL"/><appender-ref ref="SysAppender"/></root><!-- Print only messages of level DEBUG or above in the packages --><logger name="WebLogger"><level value="ALL"/></logger><appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net" ><param name="File" value="Logger/" /><param name="AppendToFile" value="true" /><param name="RollingStyle" value="Date" /><param name="DatePattern" value=""Logs_"yyyyMMdd".txt"" /><param name="StaticLogFileName" value="false" /><layout type="log4net.Layout.PatternLayout,log4net"><param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /><param name="Header" value=" ----------------------header-------------------------- " /><param name="Footer" value=" ----------------------footer-------------------------- " /></layout></appender></log4net> </configuration>

第2步，web.config里<configuration>下添加這一行

<configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> </configSections>

第3步,Properties目錄下AssemblyInfo.cs

加上這一句[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]

　　

第4步，新建一個loghelp類

public class logHelper{private static readonly log4net.ILog log = log4net.LogManager.GetLogger("WebLogger");public logHelper(){}private static void SetConfig(){object o = ConfigurationManager.GetSection("log4net");log4net.Config.XmlConfigurator.Configure(o as System.Xml.XmlElement);}public static void LogInfo(string Message){if (!log.IsInfoEnabled)SetConfig();log.Info(Message);}public static void LogInfo(string Message, Exception ex){if (!log.IsInfoEnabled)SetConfig();log.Info(Message, ex);}public static void ErrorInfo(string Message){if (!log.IsInfoEnabled)SetConfig();log.Error(Message);}public static void DebugInfo(string Message){if (!log.IsInfoEnabled)SetConfig();log.Debug(Message);}}

　　第5步調用代碼

logHelper.LogInfo("第"+sys.count+"步"+"用戶名：" + UserInfo.UserName + "修改用戶信息");

　　第6步根據業務對日志文件進行分析(圖片來自百度)

第7步
