Log4Net无法正常工作

Question

我在.NET Framework 3.5的工作使用C#在Windows XP中以管理员身份的用户,使用log4net的用于.NET Framework 2.0的二进制参考.

我曾试图什么我用log4net的缺失-没有创建日志文件,但它does`t为我工作.

我将以下内容添加到AssemblyInfo.cs中:

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4Net.config", Watch = true)]

而创建如下文件"Log4Net.config",但是,当我跑我的控制台应用程序,无法找到我的项目中的任何日志文件.我错过了什么？

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  </configSections>
  <log4net>

确保将配置文件复制到输出目录.

如果您使用的是Visual Studio,请转到"Log4Net.config"属性,并确保"复制到输出目录"设置为"始终复制"或"如果更新则复制".否则,只需确保将配置文件复制到输出目录.

此外,log4net.Appender.FileAppender没有'maximumFileSize'属性,因此您需要从配置文件中删除它.
