vinform程序配置log4net日志输出

一、第一种在AssemblyInfo.cs中添加log4net的配置//[assembly: log4net.Config.XmlConfigurator(Watch = true)]  watch表示是否监视动态加载配置文件的变动。

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
[assembly: log4net.Config.XmlConfigurator(Watch = true)]

二、第二种在winform的Program.cs中的namespace上面添加

//[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace WinForm
{
    static class Program
    {
        private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
        

三、第三种是在启动代码中添加

/// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            try
            {

                //处理未捕获的异常   
                Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
                //处理UI线程异常   
                Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
                //处理非UI线程异常   
                AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
                //读取log4net配置文件
                log4net.Config.XmlConfigurator.Configure();

四、其他就是在程序中调用和配置log4net的输出格式

1、添加log4net dll
2、在文件AssemblyInfo.cs加入一句代码,AssemblyInfo.cs的路径所在Properties目录下

[assembly: log4net.Config.DOMConfigurator(ConfigFile = "log4net.config", Watch = true)]
3、//代码中调用

添加代码如下：// 日志组件配置

//private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

 log4net.ILog log= log4net.LogManager.GetLogger(this.GetType());
 logger.Debug("调试");
 logger.Error("这是一个错误日志");
 logger.Fatal("这是一个致命的错误日志");
 logger.Warn("这是一条警告日志");
 logger.Info("这是一条普通信息");
4、配置文件
<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender,log4net">
    <param name="File" value="Logs/Log.log" />
    <param name="AppendToFile" value="true" />
    <param name="MaxSizeRollBackups" value="10" />
    <param name="MaximumFileSize" value="10MB" />
    <param name="RollingStyle" value="Size" />
    <param name="StaticLogFileName" value="true" />
    <param name="datePattern" value="yyyy-MM-dd HH:mm" />
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n" />
    </layout>
  </appender><!-- Print only messages of level DEBUG or above in the packages -->
  <logger name="WebLogger">
    <level value="DEBUG"/>
  </logger>
  
  <appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net" >
    <param name="File" value="logs/" />
    <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>
  <appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net">
    <layout type="log4net.Layout.PatternLayout,log4net">
      <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
    </layout>
  </appender>

<root>
    <!--<level value="DEBUG" />-->
    <priority value="ERROR" />
    <appender-ref ref="RollingLogFileAppender" />
  </root>
</log4net>

添加代码如下：// 日志组件配置

[assembly: log4net.Config.DOMConfigurator(ConfigFile = "log4net.config", Watch = true)]
3、//代码中调用
