如何跟踪log4net的问题 [英] How to track down log4net problems

问题描述

我用log4net的所有的时间，但有一点我从来没有想通了，是如何分辨什么在里面怎么回事。例如，我有一个控制台附加目的地，并在我的项目数据库的appender。我做了一些更改数据库和code，而现在的数据库附加器不工作了。我会找出原因，最终，但它会帮助很多，如果我可以看到这是怎么回事里面log4net的。

I use log4net all the time, but one thing I've never figured out is how to tell what's going on on the inside. For example, I've got a console appender and a database appender in my project. I made a few changes to the database and the code, and now the database appender doesn't work anymore. I'll figure out why eventually, but it would help a lot if I could see what's going on inside log4net.

请问log4net的生成任何类型的输出，我可以看到，尝试确定我的问题的根源？

Does log4net generate any kind of output that I can view to try to determine the source of my problem?

推荐答案

首先，你必须在应用程序配置文件中设置这个值：

First you have to set this value on the application configuration file:

<configuration>
   <appSettings>
      <add key="log4net.Internal.Debug" value="true"/>
   </appSettings>
</configuration>

然后，确定要救你可以在同一个config文件中添加以下code的输出文件：

Then, to determine the file in which you want to save the output you can add the following code in the same .config file:

<configuration>
...

<system.diagnostics>
    <trace autoflush="true">
        <listeners>
            <add 
                name="textWriterTraceListener" 
                type="System.Diagnostics.TextWriterTraceListener" 
                initializeData="C:\tmp\log4net.txt" />
        </listeners>
    </trace>
</system.diagnostics>

...
</configuration>
