实体框架DbSet包含0条记录
问题描述：
所以我有以下问题：
我有一些Vehicle实体，它对应于数据库中的一个表。但是，当我尝试使用以下行来检索所有记录时：
I have some Vehicle entity that corresponds to a table in the DB. But when I try to retrieve ALL the records with the following line :
var vehicles = db.VehicleSet.ToList();
作为结果，我得到了零对象……而数据库中的表大约为0。 18k条记录。
I get ZERO objects as result ... whilst the table in the DB has approx. 18k records.
任何想法可能出在哪里，或者问题太模糊了？
Any idea where the problem might be, or is the question too vague?
答
我知道了。原来这是数据库的问题。在我的结构中，我使用的是 Discriminator字段，该字段未设置并且会导致问题。
I Figured it out. Turns out it was a problem with the Database. In my structure I was using a "Discriminator" field which was not set and was causing problems.
谢谢您的时间。
