C# 代码 手工 配置 Log4Net 2种方法

这个初始化要在 获取 ILog 接口的代码之前完成, 之后按通常方式使用 log4net 就行了.

不用携带 config 配置文件.

方法1：

        /// <summary>

        /// 使用文本记录异常日志

        /// </summary>

        /// <Author>Ryanding</Author>

        /// <date>2011-05-01</date>

        public void LoadFileAppender()

        {

            string currentPath = AppDomain.CurrentDomain.BaseDirectory;

            currentPath = Path.Combine(currentPath, @"Log");



            string txtLogPath = Path.Combine(currentPath, "ErrorLog.txt");



            log4net.Repository.Hierarchy.Hierarchy hier =

                (log4net.Repository.Hierarchy.Hierarchy)log4net.LogManager.GetRepository();



            if (hier != null)

            {

                FileAppender fileAppender = new FileAppender();

                fileAppender.Name = "LogFileAppender";

                fileAppender.File = txtLogPath;

                fileAppender.AppendToFile = true;



                PatternLayout patternLayout = new PatternLayout

                {

                    ConversionPattern =

                        "记录时间：%date 线程ID:[%thread] 日志级别：%-5level 出错类：%logger property:[%property{NDC}] - 错误描述：%message%newline"

                };

                patternLayout.ActivateOptions();

                fileAppender.Layout = patternLayout;



                //选择UTF8编码，确保中文不乱码。

                fileAppender.Encoding = Encoding.UTF8;



                fileAppender.ActivateOptions();

                BasicConfigurator.Configure(fileAppender);

            }

        }

 

方法2：

    static bool InitializeLogSystem()

    {

      // 通过配置文件偷来的配置项

      //<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">

      //  <file value="Data/RollingLogFile.log" />

      //  <appendToFile value="true" />

      //  <maxSizeRollBackups value="3" />

      //  <maximumFileSize value="1MB" />

      //  <rollingStyle value="Size" />

      //  <staticLogFileName value="true" />

      //  <layout type="log4net.Layout.PatternLayout">

      //    <conversionPattern value="%date [%thread] %-5level %logger [%property{url}] - %message%newline" />

      //  </layout>

      //</appender>

      log4net.Appender.RollingFileAppender appender = new log4net.Appender.RollingFileAppender();

      // winform 的取路径方式呢

      appender.File = System.IO.Path.Combine(Application.StartupPath, "RollingLogFile.log");

      appender.AppendToFile = true;

      appender.MaxSizeRollBackups = 3;

      appender.MaximumFileSize = "1MB";

      appender.RollingStyle = log4net.Appender.RollingFileAppender.RollingMode.Size;

      appender.StaticLogFileName = true;

      appender.Layout = new log4net.Layout.PatternLayout("%date [%thread] %-5level - %message%newline");

      appender.ActivateOptions();// 这个要调用一下呢

      log4net.Config.BasicConfigurator.Configure(appender);

      return true;

    }
