ASP.NET Web 应用程序文件路径(在 Azure 上发布)

>问题：对于一个学校项目，我创建了一个REST Web服务，该服务与一个数据库链接，该数据库从excel文件中获取他的数据。在我的迁移/配置类中.cs我读取了 excel 文件并将它们放入数据库中。但是当我尝试在 Azure 上发布我的项目时，他似乎找不到 excel 文件，我完全不知道该 excel 文件的路径应该是什么。(当我将配置的种子方法更改为一些硬编码的东西时，它确实有效.cs(。我已经尝试将路径更改为Server.MapPath或HttpRuntime.AppDomainAppPath，但它不起作用...有没有人知道如何解决这个问题？多谢！！！
