在创建 Code First 集合时,您可以实现一个自定义类来实现 ICollection 接口。以下代码仅为概念示例,非实际代码。
public class Product
{
public int ProductId { get; set; }
public string Name { get; set; }
public Category Category { get; set; }
}
public class Category
{
public int CategoryId { get; set; }
public string Name { get; set; }
//Want to Avoid This
public ICollection<Product> Products { get; set; }
//Use his instead of above
public ProductList ProductsInCategory {get;set;}
}
public class ProductsList :ICollection<Product>
{
public int DiscontinuedProductsCount
{
return internalList.Count();
}
//Icollection Methods Excluded
}
