Log4net

# Log4net使用
首先，当然是引用nuget程序包，然后需要添加log4net的配置文件,该文件在项目中CfgFiles文件夹下创建log4net.xml，并且设置属性如果较新则复制
<?xml version="1.0" encoding="utf-8"?>
<log4net>
<!-- Define some output appenders -->
<appender name="rollingAppender" type="log4net.Appender.RollingFileAppender">
<file value="log\" />
<!--追加日志内容-->
<appendToFile value="true" />
<!--防止多线程时不能写Log,官方说线程非安全-->
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<!--可以为:Once|Size|Date|Composite-->
<!--Composite为Size和Date的组合-->
<rollingStyle value="Composite" />
<!--当备份文件时,为文件名加的后缀-->
<datePattern value="yyyyMMdd/yyyy-MM-dd"-log.txt"" />
<!--<datePattern value='yyyy-MM-dd/yyyy-MM-dd"_log.txt"'/>-->
<!--日志最大个数,都是最新的-->
<!--rollingStyle节点为Size时,只能有value个日志-->
<!--rollingStyle节点为Composite时,每天有value个日志-->
<maxSizeRollBackups value="20" />
<!--可用的单位:KB|MB|GB-->
<maximumFileSize value="5MB" />
<!--置为true,当前最新日志文件名永远为file节中的名字-->
<staticLogFileName value="false" />
<!--输出级别在INFO和ERROR之间的日志-->
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="INFO" />
<param name="LevelMax" value="FATAL" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline"/>
</layout>
</appender>
<!-- levels: OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL -->
<root>
<priority value="ALL"/>
<level value="ALL"/>
<appender-ref ref="rollingAppender" />
</root>
</log4net>

其次，添加Logger公共类
public class Logger
{
static Logger()
{
XmlConfigurator.Configure(new FileInfo(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "CfgFiles\\log4net.xml")));
ILog Log = LogManager.GetLogger(typeof(Logger));
Log.Info("系统初始化Logger模块");
}
private ILog loger = null;
public Logger(Type type)
{
loger = LogManager.GetLogger(type);
}
/// <summary>
/// Log4日志
/// </summary>
/// <param name="msg"></param>
/// <param name="ex"></param>
public void Error(string msg = "出现异常", Exception ex = null)
{
Console.WriteLine(msg);
loger.Error(msg, ex);
}
/// <summary>
/// Log4日志
/// </summary>
/// <param name="msg"></param>
public void Warn(string msg)
{
Console.WriteLine(msg);
loger.Warn(msg);
}
/// <summary>
/// Log4日志
/// </summary>
/// <param name="msg"></param>
public void Info(string msg)
{
Console.WriteLine(msg);
loger.Info(msg);
}
/// <summary>
/// Log4日志
/// </summary>
/// <param name="msg"></param>
public void Debug(string msg)
{
Console.WriteLine(msg);
loger.Debug(msg);
}
}

最后，在需要使用的地方创建Logger的实例
private Logger logger=new Logger(typeof(DiapatcherManager));
