Question

问题：对于学校项目，我创建了一个REST Web服务，该服务与从excel文件中获取数据的数据库链接。在我的Migration / Configuration.cs类中，我读取了excel文件并将它们放在数据库中。但是当我尝试在Azure上发布我的项目时，他似乎无法找到excel文件，我完全不知道该excel文件的路径应该是什么。（当我将Configuration.cs的种子方法更改为某些硬编码的东西时，它确实有效）。我已经尝试将路径更改为Server.MapPath或HttpRuntime.AppDomainAppPath，但它没有工作......有没有人知道如何解决这个问题？非常感谢!!!

Configuration.cs：

    using System.Data.Entity;
    using System.Data.Entity.Migrations;

    using System.Web;
    using WineFoodModel;
    internal sealed class Configuration : DbMigrationsConfiguration<RestServiceTest.Models.WineRestTestContext>
    {
        public Configuration()
        {
            AutomaticMigrationsEnabled = false;
        }

        protected override void Seed(RestServiceTest.Models.WineRestTestContext context)
        {
            //  This method will be called after migrating to the latest version.

            //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
            //  to avoid creating duplicate seed data. E.g.
            //
            //    context.People.AddOrUpdate(
            //      p => p.FullName,
            //      new Person { FullName = "Andrew Peters" },

您是否将excel文件包含在项目中？（构建后，检查bin文件夹）。如果没有，请包括您的excel文件。

部署到Azure（我假设为Azure App Service）时，文件的绝对路径为

Environment.ExpandEnvironmentVariables(@"%HOME%\site\wwwroot\{relative file path}")

ASP.NET Web应用程序文件路径（在Azure上发布）
