log4net 有四种主要的组件，分别是Logger（记录器）, Repository（库）, Appender（附着器）以及 Layout（布局）.
Log4net框架定义了一个ILog接口，所有的logger类都必须实现这个接口。如果你想实现一个自定义的logger，你必须首先实现这个接口。你可以参考在/extension目录下的几个例子。
log4net.Layout.PatternLayout中的转换模式(ConversionPattern)
%m(message):输出的日志消息，如ILog.Debug(…)输出的一条消息
%n(new line):换行
%d(datetime):输出当前语句运行的时刻
%r(run time):输出程序从运行到执行到当前语句时消耗的毫秒数
%t(thread id):当前语句所在的线程ID
%p(priority): 日志的当前优先级别，即DEBUG、INFO、WARN…等
%c(class):当前日志对象的名称，例如：
模式字符串为：%-10c -%m%n
代码为：
ILog log=LogManager.GetLogger(“Exam.Log”);
log.Debug(“Hello”);
则输出为下面的形式：
Exam.Log - Hello
%L：输出语句所在的行号
%F：输出语句所在的文件名
%-数字：表示该项的最小长度，如果不够，则用空格填充
Logger
作用：直接与应用交互的组件，用于触发日志事件
级别（日志事件） 优先级
OFF 6
FATAL 5
ERROR 4
WARN 3
INFO 2
DEBUG 1
ALL 0
