下面小編就為大家分享一篇C#中四步輕松使用log4net記錄本地日志的方法，具有很好的參考價(jià)值。希望對(duì)大家有所幫助

在這里，記錄我在項(xiàng)目中使用log4net記錄本地日志的步驟。在不會(huì)之前感覺很難，很神秘，一旦會(huì)了之后其實(shí)沒那么難。其實(shí)所有的事情都是一樣的，下面我就分享一下我使用log4Net的經(jīng)驗(yàn)。

第一步：首先從Visual Studio中的Nuget包管理中搜索下載 Log4Net dll文件如下圖：

選擇安裝的項(xiàng)目(哪個(gè)類庫中需要記錄日志就勾選上)

第二步：打開配置文件 WinFrom就是 App.config Web就是 web.config 將以下配置信息加入

<configSections>
 <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>

以上節(jié)點(diǎn)具體參數(shù)這里不做解釋，可以上網(wǎng)查詢幫助文檔

注意：這兩段XML要放在configuration 節(jié)點(diǎn)下靠前
