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 = , Price = 12.1m, Description = "1test", ImageURL = "1.jpg"},
                     new Product {SKU = , Price = 12.2m, Description = "2test", ImageURL = "2.jpg"},
                     new Product {SKU = , Price = 12.3m, Description = "3test", ImageURL = "3.jpg"},
                     new Product {SKU = , Price = 12.4m, Description = "4test", ImageURL = "4.jpg"},
                     new Product {SKU = , Price = 12.5m, Description = "5test", ImageURL = "5.jpg"},
                     new Product {SKU = , 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();
             }
          }
