给定以下课程
public class Company
{
public List<Product> Products { get; set; }
}
public class Product
{
public Guid Id { get; set; }
public List<ProductPermission> Permissions { get; set; }
}
public class ProductPermission
{
public Guid Id { get; set; }
public string Name { get; set; }
}
鉴于我知道产品 ID,将产品权限添加到现有产品的最佳方式是什么?
