Super detailed Log4Net configuration

1. Add the following code to AssemblyInfo.cs of the assembly that needs to output logs

 

/// <summary>
///Log4Net 的摘要说明
/// </summary>
//注意下面的语句一定要加上，指定log4net使用.config文件来读取配置信息
//如果是WinForm（假定程序为MyDemo.exe，则需要一个MyDemo.exe.config文件）
//如果是WebForm，则从web.config中读取相关信息
[assembly: log4net.Config.XmlConfigurator(Watch = true)]

2. Add the following configuration in web.config or App.config

 

 

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
