log4net异步中的FileNotFoundException异常

Question

我正在尝试使用log4net创建一个用于日志记录的库我从安装了log4net.async，我从控制台应用程序调用它来登录数据库和文件。

它在log4net内部日志中给出了错误

log4net: Configuration update mode [Merge].
log4net: Loading Appender [asyncForwarder] type: [Log4Net.Async.AsyncForwardingAppender,Log4Net.Async]
log4net:ERROR Could not create Appender [asyncForwarder] of type [Log4Net.Async.AsyncForwardingAppender,Log4Net.Async]. Reported error follows.

由于程序集未在代码中直接引用，因此可能未将其复制到bin文件夹中。

尝试将其包含在Visual Studio项目中，但将其属性设置为

• 构建Acton =内容
• 复制到输出目录=始终复制

另一个选择是尝试将对Log4Net.Async.DLL的引用直接添加到您的顶级项目（控制台应用程序）。
