1 public class Product
2 {
3 [Key]
4 [DatabaseGenerated(DatabaseGeneratedOption.None)]
5 public int SKU { get; set; }
6 public string Description { get; set; }
7 public decimal Price { get; set; }
8 public virtual string ImageURL { get; set; }
9 }
10
11 public class ProductContext : DbContext
12 {
13 public DbSet<Product> Products { get; set; }
14 protected override void OnModelCreating(DbModelBuilder modelBuilder)
15 {
16 base.OnModelCreating(modelBuilder);
17 modelBuilder.Entity<Product>()
18 .Map(m =>
19 {
20 m.Properties(p => new {p.SKU, p.Price, p.Description});
21 m.ToTable("Table1");
22 }).Map(m =>
23 {
24 m.Properties(p => new {p.SKU, p.ImageURL});
25 m.ToTable("Table2");
26 });
27 }
28 }
怎麼使用
1 static void Main(string[] args)
2 {
3 using (var context=new ProductContext())
4 {
5
6 var products = new List<Product>
7 {
8 new Product {SKU = 1, Price = 12.1m, Description = "1test", ImageURL = "1.jpg"},
9 new Product {SKU = 2, Price = 12.2m, Description = "2test", ImageURL = "2.jpg"},
10 new Product {SKU = 3, Price = 12.3m, Description = "3test", ImageURL = "3.jpg"},
11 new Product {SKU = 4, Price = 12.4m, Description = "4test", ImageURL = "4.jpg"},
12 new Product {SKU = 5, Price = 12.5m, Description = "5test", ImageURL = "5.jpg"},
13 new Product {SKU = 6, Price = 12.6m, Description = "6test", ImageURL = "6.jpg"}
14 };
15 context.Products.AddRange(products);
16 context.SaveChanges();
17 }
18 using (var context = new ProductContext())
19 {
20 foreach (var product in context.Products)
21 {
22 Console.WriteLine("{0}--{1}--{2}--{3}", product.SKU, product.Price, product.Description,
23 product.ImageURL);
24 }
25 Console.ReadKey();
26 }
27 }
生成表結構
執行效果
