GG_Logs 日志类库封装使用说明

3.6、GG_Logs 日志类库封装使用说明

GG_Logs类库项目，Nuget安装log4net

添加代码配置代码：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = false)]

添加操作类代码（Log4Net.cs）：

using System;

using System.Collections.Generic;

using System.Diagnostics;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using log4net;

namespace GG_Logs

{

public static class Log4Net

{

public static void Debug(object message)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Debug(message);

}

public static void Debug(object message, Exception ex)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Debug(message, ex);

}

public static void Error(object message)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Error(message);

}

public static void Error(object message, Exception exception)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Error(message, exception);

}

private static string GetCurrentMethodFullName()

{

try

{

StackFrame frame;

string str2;

int num = 2;

StackTrace trace = new StackTrace();

int length = trace.GetFrames().Length;

do

{

frame = trace.GetFrame(num++);

str2 = frame.GetMethod().DeclaringType.ToString();

}

while (str2.EndsWith("Exception") && (num < length));

string name = frame.GetMethod().Name;

return (str2 + "." + name);

}

catch

{

return null;

}

}

public static void Info(object message)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Info(message);

}

public static void Info(object message, Exception ex)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Info(message, ex);

}

public static void Warn(object message)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Warn(message);

}

public static void Warn(object message, Exception ex)

{

LogManager.GetLogger(GetCurrentMethodFullName()).Warn(message, ex);

}

}

}

在使用的项目中引用类的GG_Logs.dll，新建文件log4net.config 并添加配置代码：

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<configSections>

<section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>

</configSections>

<log4net>

<!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->

<!-- Set root logger level to ERROR and its appenders -->

<root>

<level value="ALL" />

<appender-ref ref="SysAppender" />

</root>

<!-- Print only messages of level DEBUG or above in the packages -->

<logger name="WebLogger">

<level value="DEBUG" />

</logger>

<appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net">

<!--文件名称-->

<appendToFile value="true"/>

<param name="File" value="C:/Logs/" />

<param name="AppendToFile" value="true" />

<param name="RollingStyle" value="Date" />

<!--文件名称-->

<param name="DatePattern" value="&quot;Logs_&quot;yyyyMMdd&quot;.txt&quot;" />

<param name="StaticLogFileName" value="false" />

<!--设置无限备份=-1 ，最大备份数为1000-->

<param name="MaxSizeRollBackups" value="1000"/>

<!--每个文件的大小-->

<param name="MaximumFileSize" value="500KB"/>

<layout type="log4net.Layout.PatternLayout,log4net">

<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

</layout>

</appender>

<appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net">

<layout type="log4net.Layout.PatternLayout,log4net">

<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

</layout>

</appender>

</log4net>

</configuration>

调用代码很简单。

using GG_Logs;

Log4Net.Error("hhhhhhhhhhhhh");

实际项目调用，建立mvc模式的web项目，项目名称Web。

当前mvc项目想创建一个log4net.config 日志配置文件：代码如下

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<configSections>

<section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>

</configSections>

<log4net>

<!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->

<!-- Set root logger level to ERROR and its appenders -->

<root>

<level value="ALL" />

<appender-ref ref="SysAppender" />

</root>

<!-- Print only messages of level DEBUG or above in the packages -->

<logger name="WebLogger">

<level value="DEBUG" />

</logger>

<appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net">

<!--文件名称-->

<appendToFile value="true"/>

<param name="File" value="D:/Logs/" />

<param name="AppendToFile" value="true" />

<param name="RollingStyle" value="Date" />

<!--文件名称-->

<param name="DatePattern" value="&quot;Logs_&quot;yyyyMMdd&quot;.txt&quot;" />

<param name="StaticLogFileName" value="false" />

<!--设置无限备份=-1 ，最大备份数为1000-->

<param name="MaxSizeRollBackups" value="1000"/>

<!--每个文件的大小-->

<param name="MaximumFileSize" value="500KB"/>

<layout type="log4net.Layout.PatternLayout,log4net">

<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

</layout>

</appender>

<appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net">

<layout type="log4net.Layout.PatternLayout,log4net">

<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

</layout>

</appender>

</log4net>

</configuration>

当前项目添加引用

打开HomeController.cs 控制器 ，添加代码

using GG_Logs;  //命名空间引用

Index()方法加入代码Log4Net.Error("hhhhhhhhhhhhh");

运行项目，在D盘logs文件夹下有txt文本，日志操作完成。
