log4g使用《轉》

 

log4net:http://logging.apache.org/log4net/download.html 下載 incubating-log4net-1.2.10.zip 在webform開發環境中,log4net的配置必須放在網站根目錄下的web.config中, 添加以下配置 <configSections>     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> 上邊的配置必須緊挨著<configuration>,否則會提示錯誤 "Error    49    D:\wwwroot\Default.aspx: ASP.NET runtime error: 每個設定檔中只允許存在一個 <configSections> 元素，並且，如果存在該元素，它還必須是根 <configuration> 元素的第一個子項目。 (D:\wwwroot\web.config line 18)    D:\wwwroot\Default.aspx    1    1    D:\wwwroot\ " 然後添加 <!-- log4net配置聲明 --> <log4net>     <appender name="LogFileAppender" type="log4net.Appender.FileAppender">       <!-- Please make shure the ..\\Logs directory exists! -->       <param name="File" value="Logs\\Log4Net.log"/>       <!--<param name="AppendToFile" value="true"/>-->       <layout type="log4net.Layout.PatternLayout">         <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>       </layout>     </appender>     <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">       <to value="" />       <from value="" />       <subject value="" />       <smtpHost value="" />       <bufferSize value="512" />       <lossy value="true" />       <evaluator type="log4net.Core.LevelEvaluator">         <threshold value="WARN"/>       </evaluator>       <layout type="log4net.Layout.PatternLayout">         <conversionPattern value="%newline%date [%thread] %-5level %logger [%property] - %message%newline%newline%newline" />       </layout>     </appender>     <logger name="File">       <level value="All" />       <appender-ref ref="LogFileAppender" />     </logger>     <logger name="EmailLog">       <level value="All" />       <appender-ref ref="SmtpAppender" />     </logger> </log4net> 需要注意的是,多數網上的教程都提到,需要在AssemblyInfo.cs檔案中, [assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)] 按照要求做了可是寫不到檔案裡?怎麼回事? 後來在CSDN中找到了答案,大意就是說,VS2005(我使用的VS2008)中,不會產生固定名稱的DLL 不保證上行代碼總被執行,建議款封裝成靜態類 按此說法,經實驗表明是可取的!~以下為封裝好了的Log類,在保證上述要求後,記得添加DLL引用, 然後直接Copy下邊的代碼就可以了. using System;
