這邊先介紹簡單的使用：在控制臺輸出和寫入文件
首先添加log4net的nuget包
然后在app.config中添加配置項==configSections只能有一個，且是configuration的首個節點

這部分代碼也可以單獨放在一個配置文件中，起名log4net.config,我們把這個文件和app.config放在同一層
接著在AssemblyInfo.cs下添加特性

//配置文件在app.config中[assembly: log4net.Config.XmlConfigurator(Watch = true)]//配置文件在log4net.config中//[assembly: log4net.Config.XmlConfigurator(ConfigFile="log4net.config", Watch = true)] |
Watch=true監視配置文件，當配置文件發生變化的時候，就會重新加載。
