Log4Net日志配置附帶源碼下載這篇文章主要介紹了 Log4Net日志配置附帶源碼下載需要的朋友可以參考下 前述園子里有許多人對10g4net這款開源的日志記錄控件有很多介紹。在這里個(gè)人再做一次 總結(jié)，希望對以后有所幫助，需要的時(shí)候可以直接使用，減少查閱資料的時(shí)間。 利用10g4net可以方便地將日志信息記錄到文件、控制臺、Windows事件日志和數(shù)據(jù)庫，并且我們還可以記載控制要記載的日志級別，可以記載的日志類別包括：FATAL（致命錯(cuò)誤）、ERROR（一般錯(cuò)誤）、WARN （警告）、INFO （一般信息）、DEBUG （調(diào)試信息）。10g4net有四種主要的 組件，分別是Logger （記錄器），Repository （庫），Appender （附著器）以及Layout （布局）. 準(zhǔn)備工作：1.下載 log4net.dll 下載地址http:/logging.apache.org/log4net/download_log4net.cgi 下載文件：log4net-1213-bin-newkey.zip。解壓選擇對應(yīng)的
