利用log4添加log

應用log4net.dll

新建Global.asax，在cs文件中添加

protected void Application_Start(object sender, EventArgs e)
        {
            #region system log init
            log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(AppDomain.CurrentDomain.BaseDirectory + @"\Log.config"));
            #endregion
        }

添加Log.config文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
