在启动时，请拨打：

XmlConfigurator.Configure();

在你的web.config中的appSettings指定log4net.Config：

In your Web.config, specify log4net.Config in appSettings:

<add key="log4net.Config" value="Log.config" />

这个特殊的设置允许您更改日志配置而无需重新编译。特别是有帮助的多个环境之间移动。

This special setting allows you to change the log configuration without having to recompile. Especially helpful for moving between multiple environments.

示例

考虑以下项目文件的结构：

Consider the following project file structure:

\config\log4net\debug.config
\config\log4net\staging.config
\config\log4net\release.config
\config\appSettings\debug.config
\config\appSettings\staging.config
\config\appSettings\release.config

应用程序和日志记录配置尊贵为每个环境。引用到日志记录配置保持在应用程序设置。

Application and logging configurations are distinguished for each environment. References to the logging configurations are maintained in the application settings.

的 \\ CONFIG \\的appSettings \\ debug.config 的：

<appSettings>
    <add key="log4net.Config" value="config\log4net\debug.config" />
    ...
</appSettings>

的 \\ CONFIG \\的appSettings \\ staging.config 的：

<appSettings>
    <add key="log4net.Config" value="config\log4net\staging.config" />
    ...
</appSettings>

的 \\ CONFIG \\的appSettings \\将release.config 的：

<appSettings>
    <add key="log4net.Config" value="config\log4net\release.config" />
    ...
</appSettings>

变化的环境是在Web.config中更新文件的appSettings一个简单的事情。

Changing environments is a simple matter of updating the appSettings file in Web.config.

<appSettings file="config\appSettings\staging.config">
    ...
</appSettings>
