log4net日誌記錄
1、1.在assemblyInfo.cs新增
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
2、2.在根目錄新增log4net.config檔案，內容如下：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net>
<logger name="log" additivity="false">
<level value="ALL"/>
<appender-ref ref="SysAppender" />
</logger>
<!--Oracle資料庫-->

<commandText value="INSERT INTO SYS_LOG(Dates,Levels,Logger,Message,Exception,ClientUser,ClientIP,RequestUrl,Action)VALUES(:Dates,:Levels,:Logger,:Message,:Exception,:ClientUser,:ClientIP,:RequestUrl,:Action)"/>

呼叫例項
log4net.ILog log = log4net.LogManager.GetLogger("Filelog");
log.Info(Message);
%m(message):輸出的日誌訊息，如ILog.Debug(…)輸出的一條訊息
%n(new line):換行
%d(datetime):輸出當前語句執行的時刻
%r(run time):輸出程式從執行到執行到當前語句時消耗的毫秒數
%t(thread id):當前語句所在的執行緒ID
%p(priority): 日誌的當前優先順序別，即DEBUG、INFO、WARN…等
%c(class):當前日誌物件的名稱
%L：輸出語句所在的行號
%F：輸出語句所在的檔名
%-數字：表示該項的最小長度，如果不夠，則用空格填充
例如，轉換模式為%r [%t]%-5p %c - %m%n 的 PatternLayout 將生成類似於以下內容的輸出：
176 [main] INFO org.foo.Bar - Located nearest gas station.
-->
3、可定義個日誌幫助類，如下：
public static class LogHelper
{
static ILog log = LogManager.GetLogger("log");
public static void Save(string content,Exception ex)
{
log.Error(content, ex);
}
public static void Save(string content)
{
log.Error(content);
}
public static void SaveAsyn(string content)
{
Task.Run( ()=> log.Error(content));
}
public static void SaveAsyn(string content,Exception ex)
{
Task.Run(() => log.Error(content, ex));
}
}
3 按日期及檔案大小記錄
<appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net">
<param name="File" value="datalog" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Composite" />
<param name="DatePattern" value="\\yyyy-MM-dd".log"" />
<param name="StaticLogFileName" value="false" />
<param name="MaximumFileSize" value="1MB" />
<param name="MaxSizeRollBackups" value="-1" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d - %m%n" />
<param name="Header" value="
----------------------begin--------------------------
" />
<param name="Footer" value="
----------------------end--------------------------
" />
</layout>
