C# 通过log4net记录日志

1.添加log4net 引用

 

 2. 在app.config中添加配置

 1 <configuration>
 2   <configSections>
 3     <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
 4       <section name="AdjustMeter.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
 5     </sectionGroup>
 6     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
 7   </configSections>
 8   <system.diagnostics>

18     </sources>

26       <!-- 取消以下部分的注释，并用应用程序名替换 APPLICATION_NAME，以写入应用程序事件日志-->
27       <!--<add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="APPLICATION_NAME"/> -->

3.添加类 LogHelper,记录调用方法、行号

 1 private static ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
 2 
 3         /// <summary>
 4         /// 记录Winform页面日志
 5         /// </summary>
 6         /// <param name="msg">日志信息</param>
 7         public static void Info(string msg)
 8         {
 9             System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(true);
10             msg =  msg + "\r\n [方法名："+ st.GetFrame(2).GetMethod().Name + " 行号：" + st.GetFrame(2).GetFileLineNumber().ToString() + "]";
11             log.Info(msg);
12         }
13 
14         /// <summary>
15         /// 记录服务端日志
16         /// </summary>
17         /// <param name="msg">日志信息</param>
18         public static void ServiceLog(string msg)
19         {
20             System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(true);
21             msg = msg + "\r\n [方法名：" + st.GetFrame(2).GetMethod().Name + " 行号：" + st.GetFrame(2).GetFileLineNumber().ToString() + "]";
22             log.Error(msg);
23         }
24 
25         /// <summary>
26         /// 记录调试信息日志
27         /// </summary>
28         /// <param name="msg">日志信息</param>
29         public static void Debug(string msg)
30         {
31             System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(true);
32             msg = msg + "\r\n [方法名：" + st.GetFrame(2).GetMethod().Name + " 行号：" + st.GetFrame(2).GetFileLineNumber().ToString() + "]";
33             log.Debug(msg);
34         }

 --------------------------------------

winform程序需要在Program.cs 添加

 log4net.Config.XmlConfigurator.Configure(); log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo("~/App.config"));
