注意：數據庫

//若是爲了使得應用程序的配置文件（web/app.config）不至於很臃腫，把log4net的配置單獨放置在
//Log4net.config文件中，那麼須要應用程序的AssemblyInfo.cs添加這行代碼。目的是程序啓動時是找到Log4net.config配置文件。windows

 

 

 

也能夠用代碼進行配置：架構

請在 應用程序啓動前調用：app

        private void LoadLog4netConfig()
        {
            string filePath = Server.MapPath("~/Config/Log4net.config");
            FileInfo fileInfo = new FileInfo(filePath);
            //DOMConfigurator已經被XmlConfigurator取代
            //log4net.Config.DOMConfigurator.Configure(fileInfo);
            XmlConfigurator.ConfigureAndWatch(fileInfo);
        }

注意：框架

  若是是分層架構中，假設LoadLog4netConfig是在程序集1中調用ide

string filePath = Server.MapPath("~/Config/Log4net.config");
 

仍是指的是調用了程序集1的應用程序的目錄

~/Config/Log4net.config
尋找，

故，配置文件Log4net.config應該添加在調用log4net的程序集中
 

 
 

一些代碼的用法示例：函數
 

 
 
        protected void Button1_Click(object sender, EventArgs e)
        {
            //註釋掉其餘全部的Loger,只用<root>這個父loger
            //再把已經註釋掉其餘的Loger的<appender-ref ref="LogFileAppender" />
            //複製到<root>，能夠同時進行全部子loger向的日誌方案
            ILog rootLog = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            rootLog.Debug("I'm rootLoger");

            //ILog logFileAppenderLoggingExample = LogManager.GetLogger("LogFileAppender.LoggingExample");
            //ILog consoleAppLoggingExample = LogManager.GetLogger("ConsoleApp.LoggingExample");
            
            //if (null != logFileAppenderLoggingExample)
            //{
            //    logFileAppenderLoggingExample.Debug("Hello, I'm LogFileAppender.LoggingExample, nothing, just say hello! ");
            //    consoleAppLoggingExample.Debug("Hello, I'm consoleAppLoggingExample, nothing, just say hello! ");
            //}
        }

    則缺省爲DEBUG。能夠經過<appender-ref>標籤訂義日誌對象使用的Appender對象。
    <appender-ref>聲明瞭在其餘地方定義的Appender對象的一個引用。
    在一個logger對象中的設置會覆蓋根日誌的設置。
    而對Appender屬性來講，子日誌對象則會繼承父日誌對象的Appender列表。
