利用实体框架挽救物体
原标题:Save collection of object using Entity Framework

我正在利用实体框架获取我的数据库。

在移民方面,我看到,设立了2个表格:

  1. Shop
  2. Product

我创建了商店,并将产品添加到产品上——但在数据库中,我看到只有商店项目除外,产品表是空的。

我是否需要再有一份<代码>DbSet<Product>,并将产品与本表格相同?

或者还有任何其他方式?

I am writing my code in C# and running on .NET Core 8.

 public class MyContext : DbContext
 {
     public DbSet<Shop> ShopItems { get; set; }
 }

 public class Shop
 {
     [Key]
     public string UniqId {get;set;}
     public List<Product> Products {get;set;}
 }

 public class Product
 {
     [Key]
     public string UniqId {get;set;}
     public double Price {get;set;}
     public String Name {get;set;}
 }
问题回答

添加<代码>DbSet<Product>至MyContext/code>

 public class MyContext : DbContext
 {
     public DbSet<Shop> ShopItems { get; set; }
     public DbSet<Product> ProductItems { get; set; }
 }

 public class Shop
 {
     [Key]
     public string UniqId {get;set;}
     public List<Product> Products {get;set;}
 }

 public class Product
 {
     [Key]
     public string UniqId {get;set;}
     public double Price {get;set;}
     public String Name {get;set;}
 }

如果这没有帮助,请提供客户代码? (你添加产品守则)
