c# - 无法加载文件或程序集，因为 'Access is denied'(标识 : NETWORK SERVICE)

Question

加载项目时出现以下错误。应用程序池标识设置为“网络服务”。“NETWORK SERVICE”作为“安全权限”对下面提到的 ASP.NET TEMP 目录具有完全访问权限。我应该怎么做才能解决以下问题？

如果您的站点使用模拟，负载可能会在用户帐户下发生(而不是 AppPool 进程的帐户)。您可以在异常时刻通过检查 Environment.UserName 来确认。

如果是这种情况，您需要确保触发程序集加载的代码在进程帐户下运行(所有其他需要文件系统访问权限的操作也是如此)。
