.net7 控制臺使用 log4net

1.nuget 安裝 log4net

2.添加配置文件，以下是在是添加的配置文件，對log4net.config文件右擊屬性，選擇 “復制到輸出目錄”：始終復制

3.把以下內容拷貝進去

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
    </configSections>
    <log4net>
        <!--數據日志-->
        <appender name="InfoRollingFileAppender" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
            <param name="File" value="Log\Info\" />
            <param name="AppendToFile" value="true" />
            <param name="rollingStyle" value="Date" />
            <param name="datePattern" value="yyyy-MM-dd.'Info.log'" />
            <param name="staticLogFileName" value="false" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="記錄時間：%date %n日志級別：%-5level %n記錄類：%logger%n記錄描述：%message%n%n" />
            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="INFO" />
                <param name="LevelMax" value="INFO" />
            </filter>
        </appender>
        <!--錯誤日志-->
        <appender name="ErrorRollingFileAppender" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
            <param name="File" value="Log\Error\" />
            <param name="AppendToFile" value="true" />
            <param name="rollingStyle" value="Date" />
            <param name="datePattern" value="yyyy-MM-dd.'error.log'" />
            <param name="staticLogFileName" value="false" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="記錄時間：%date %n日志級別：%-5level %n出錯類：%logger%n錯誤描述：%message%n%n" />
            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="ERROR" />
                <param name="LevelMax" value="ERROR" />
            </filter>
        </appender>
        <!--調試日志-->
        <appender name="DebugRollingFileAppender" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
            <param name="File" value="Log\Debug\" />
            <param name="AppendToFile" value="true" />
            <param name="rollingStyle" value="Date" />
            <param name="datePattern" value="yyyy-MM-dd.'debug.log'" />
            <param name="staticLogFileName" value="false" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="記錄時間：%date %n日志級別：%-5level %n調試類：%logger%n日志描述：%message%n%n" />
            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="DEBUG" />
                <param name="LevelMax" value="DEBUG" />
            </filter>
        </appender>
        <root>
            <level value="DEBUG" />
            <!--文件形式記錄日志-->
            <appender-ref ref="ErrorRollingFileAppender" />
            <appender-ref ref="DebugRollingFileAppender" />
            <appender-ref ref="InfoRollingFileAppender" />
        </root>
    </log4net>
</configuration>

4.開始寫日志

5.輸出日志

6.asp.net core log4net 配置文件

<?xml version="1.0" encoding="utf-8"?>
<log4net>
	<!-- Define some output appenders -->
	<appender name="rollingAppender" type="log4net.Appender.RollingFileAppender">
		<file value="log\log.txt" />
		<!--追加日志內容-->
		<appendToFile value="true" />

		<!--防止多線程時不能寫Log,官方說線程非安全-->
		<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

		<!--可以為:Once|Size|Date|Composite-->
		<!--Composite為Size和Date的組合-->
		<rollingStyle value="Composite" />

		<!--當備份文件時,為文件名加的后綴-->
		<datePattern value="yyyyMMdd.TXT" />

		<!--日志最大個數,都是最新的-->
		<!--rollingStyle節點為Size時,只能有value個日志-->
		<!--rollingStyle節點為Composite時,每天有value個日志-->
		<maxSizeRollBackups value="20" />

		<!--可用的單位:KB|MB|GB-->
		<maximumFileSize value="3MB" />

		<!--置為true,當前最新日志文件名永遠為file節中的名字-->
		<staticLogFileName value="true" />

		<!--輸出級別在INFO和ERROR之間的日志-->
		<filter type="log4net.Filter.LevelRangeFilter">
			<param name="LevelMin" value="INFO" />
			<param name="LevelMax" value="ERROR" />
		</filter>
		<layout type="log4net.Layout.PatternLayout">
			<conversionPattern value="%date [%thread] %-5level %logger - %message%newline"/>
		</layout>
	</appender>
	<root>
		<priority value="ALL"/>
		<level value="ALL"/>
		<appender-ref ref="rollingAppender" />
	</root>
</log4net>
