C# Log4Net日志怎样实现远程记录

要实现远程记录Log4Net日志，可以使用Log4Net的远程Appender来实现。远程Appender可以将日志信息发送到远程服务器进行记录。

以下是一个简单的示例代码，演示如何使用Log4Net的AdoNetAppender将日志信息记录到远程数据库：

using log4net; using log4net.Config; using log4net.Appender; using log4net.Layout; using System;  namespace RemoteLoggingExample {     class Program     {         private static readonly ILog log = LogManager.GetLogger(typeof(Program));          static void Main(string[] args)         {             // 加载Log4Net配置文件             XmlConfigurator.Configure(new System.IO.FileInfo("log4net.config"));              log.Info("This is a remote log message.");              Console.ReadLine();         }     } } 

在log4net.config配置文件中配置AdoNetAppender来实现远程记录日志到数据库：

<log4net>   <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">     <bufferSize value="1" />     <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />     <connectionString value="Data Source=remoteServerName;Initial Catalog=loggingDB;User ID=username;Password=password;" />     <commandText value="INSERT INTO Logs (Date, Thread, Level, Logger, Message) VALUES (@log_date, @thread, @log_level, @logger, @message)" />     <parameter>       <parameterName value="@log_date" />       <dbType value="DateTime" />       <layout type="log4net.Layout.RawTimeStampLayout" />     </parameter>     <parameter>       <parameterName value="@thread" />       <dbType value="String" />       <size value="255" />       <layout type="log4net.Layout.PatternLayout">         <conversionPattern value="%thread" />       </layout>     </parameter>     <parameter>       <parameterName value="@log_level" />       <dbType value="String" />       <size value="50" />       <layout type="log4net.Layout.PatternLayout">         <conversionPattern value="%level" />       </layout>     </parameter>     <parameter>       <parameterName value="@logger" />       <dbType value="String" />       <size value="255" />       <layout type="log4net.Layout.PatternLayout">         <conversionPattern value="%logger" />       </layout>     </parameter>     <parameter>       <parameterName value="@message" />       <dbType value="String" />       <size value="4000" />       <layout type="log4net.Layout.PatternLayout">         <conversionPattern value="%message" />       </layout>     </parameter>   </appender>    <root>     <level value="ALL" />     <appender-ref ref="AdoNetAppender" />   </root> </log4net> 

需要根据实际情况修改connectionString、commandText等配置信息，确保能够正确连接到远程数据库并将日志信息记录到指定表中。
