我正在尝试使用 Entity Framework 创建一个新数据库,但我总是收到该异常
Directory lookup for the file "c:\users\oren\documents\visual studio 2012\Projects\ResturantSite\ResturantSite\App_Data\ResturantSite.SiteContext.mdf" failed with the operating system error 2(The system cannot find the file specified.).
CREATE DATABASE failed. Some file names listed could not be created. Check related errorsLine 28: using (var db = new SiteContext())
Line 29: {

Line 31: db.SaveChanges();
Line 32: }
第30行抛出异常
希望有人能帮忙
最佳答案
您的应用程序缺少 App_Data
文件夹。右键单击您的项目,选择 Add
,然后选择 Add ASP.Net Folder
并选择 App_Data
文件夹。
这确保您的应用程序存在正确的文件夹。
