Nlog直接访问有效，但PostSharp默认不可用

Question

我是关于PostSharp的工作原理的新手。我已经使用NLog编写了一些代码，希望使用PostSharp进行改进。

• Nlog输出正在工作（在控制台和文件上都完成了输出。] >>
• PostSharp根本不起作用（没有输出到文件，没有输出控制台）。>>

我试图遵循PostSharp网站上的文档：https://doc.postsharp.net/nlog

我不知道我的错误在哪里:(

有人可以帮我解决这个问题吗？

感谢您的帮助。

PostSharp仅记录带有[Log]注释的方法，并且仅在设置了后端后才开始记录日志，就像您在InitPostSharp中所做的那样。

如果您将以下方法添加到班级Program：
