将一个实体数据保存到不同的数据表中<EntityFramework6.0>

2014-11-22声明方式

 public class Product
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.None)]
        public int SKU { get; set; }
        public string Description { get; set; }
        public decimal Price { get; set; }
        public virtual string ImageURL { get; set; }
    }

    public class ProductContext : DbContext
    {
        public DbSet<Product> Products { get; set; }
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<Product>()
                .Map(m =>
                {
                    m.Properties(p => new {p.SKU, p.Price, p.Description});
                    m.ToTable("Table1");
                }).Map(m =>
                {
                    m.Properties(p => new {p.SKU, p.ImageURL});
                    m.ToTable("Table2");
                });
        }
    }

怎么使用

  static void Main(string[] args)
        {
            using (var context=new ProductContext())
            {
                
                var products = new List<Product>
                {
                    new Product {SKU = 1, Price = 12.1m, Description = "1test", ImageURL = "1.jpg"},
                    new Product {SKU = 2, Price = 12.2m, Description = "2test", ImageURL = "2.jpg"},
                    new Product {SKU = 3, Price = 12.3m, Description = "3test", ImageURL = "3.jpg"},
                    new Product {SKU = 4, Price = 12.4m, Description = "4test", ImageURL = "4.jpg"},
                    new Product {SKU = 5, Price = 12.5m, Description = "5test", ImageURL = "5.jpg"},
                    new Product {SKU = 6, Price = 12.6m, Description = "6test", ImageURL = "6.jpg"}
                };               
                context.Products.AddRange(products);
                context.SaveChanges();
            }
            using (var context = new ProductContext())
            {
                foreach (var product in context.Products)
                {
                    Console.WriteLine("{0}--{1}--{2}--{3}", product.SKU, product.Price, product.Description,
                        product.ImageURL);
                }
                Console.ReadKey();
            }
         }
