推荐答案

错误说出来确切地说，您无法在此处访问Request对象。请参阅 IIS7集成模式：请求不可用在这个背景下，Application_Start中的异常 - Mike Volodarsky的博客 [ ^ ]了解更多详情。

The error says it exactly, you cannot access the Request object here. See IIS7 Integrated mode: Request is not available in this context exception in Application_Start - Mike Volodarsky's Blog[^] for more details.
