您可以在代码中配置 log4net 而不是使用配置文件吗? [英] Can you configure log4net in code instead of using a config file?

问题描述

我了解 log4net 为何使用 app.config 文件来设置日志记录 - 这样您就可以轻松更改信息的记录方式，而无需重新编译您的代码.但就我而言，我不想将 app.config 文件与我的可执行文件打包在一起.而且我不想修改我的日志记录设置.

I understand why log4net uses app.config files for setting up logging - so you can easily change how information is logged without needing to recompile your code. But in my case I do not want to pack a app.config file with my executable. And I have no desire to modify my logging setup.

有没有办法让我设置登录代码而不是使用 app.config?

Is there a way for me to set up logging in code rather than using the app.config?

这是我的简单配置文件:

Here is my simple config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="LogsEventLog.txt" />
      <appendToFile value="false" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="1GB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="MemoryAppender" type="log4net.Appender.MemoryAppender">
    </appender>
    <root>
      <level value="Info" />
      <appender-ref ref="RollingLogFileAppender" />
      <appender-ref ref="MemoryAppender" />
    </root>
  </log4net>
</configuration>

完全清楚:我的目标是没有 XML 文件.甚至不是作为我变成流的嵌入式资源.我的目标是完全以编程方式定义记录器.只是好奇是否可能，如果可能的话，我可以在哪里找到语法示例.

To be completely clear: It is my goal to have no XML file. Not even as an embedded resource that I turn into a stream. My goal was to define the logger completely programmatically. Just curious if it's possible and if so where I might find an example of the syntax.

推荐答案

最终解决方案:₁

对于将来可能偶然发现此问题的任何人，这就是我所做的.我做了下面的静态类:

For anyone who may stumble upon this in the future, here is what I did. I made the static class below:

using log4net;
using log4net.Repository.Hierarchy;
using log4net.Core;
using log4net.Appender;
using log4net.Layout;

namespace Spectrum.Logging
{
    public class Logger
    {
        public static void Setup()
        {
            Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();

            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = "%date [%thread] %-5level %logger - %message%newline";
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = false;
            roller.File = @"LogsEventLog.txt";
            roller.Layout = patternLayout;
            roller.MaxSizeRollBackups = 5;
            roller.MaximumFileSize = "1GB";
            roller.RollingStyle = RollingFileAppender.RollingMode.Size;
            roller.StaticLogFileName = true;            
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

            MemoryAppender memory = new MemoryAppender();
            memory.ActivateOptions();
            hierarchy.Root.AddAppender(memory);

            hierarchy.Root.Level = Level.Info;
            hierarchy.Configured = true;
        }
    }
}

然后我所要做的就是用以下调用替换我调用 XML 文件的代码:

And then all I had to do was replace the code where I called the XML file with the following call:

//XmlConfigurator.Configure(new FileInfo("app.config")); // Not needed anymore
Logger.Setup();
