This is because your code is attempting to write to the event log, but the user that the application pool is running as does not have this authority.

这是因为您的代码试图写入事件日志，但是应用程序池正在运行的用户没有这个权限。

You will need to change the application pool to run as a different user or have your website impersonate a well-known user if you cannot change the app pool identity.

如果不能更改应用程序池标识，则需要更改应用程序池以作为不同的用户运行，或者让您的网站模拟知名用户。
