重构EF6实体而不是使用多个属性使用复杂类型

问题描述

我有一个类客户包含地址属性，电话属性和传真属性，但是我想将地址，电话属性取消为复杂类型。属性已作为列在数据库中。

  [Table（tblCustomer）] 
 public partial class Customer：Entity 
 {
 [Key] 
 public int CustomerID {get;组; 
 
 [StringLength（10）] 
 public string CustomerCode {get;组; 
 
 [StringLength（60）] 
 public string AddressLine1 {get;组; 
 
 [StringLength（70）] 
 public string AddressLine2 {get;组; } 
 
 [StringLength（35）] 
 public string City {get;组; 
 
 [StringLength（2）] 
 public string State {get;组; } 
 
 [StringLength（10）] 
 public string ZipCode {get;组; } 
 
 [StringLength（15）] 
 public string PhoneNo {get;组; 
 
 [StringLength（3）] 
 public string PCountryCode {get;组; 
 
 [StringLength（3）] 
 public string PAreaCode {get;组; } 
 
 [StringLength（7）] 
 public string PPhoneNo {get;组; 
 
 [StringLength（3）] 
 public string FCountryCode {get;组; } 
 
 [StringLength（3）] 
 public string FAreaCode {get;组; 
 
 [StringLength（7）] 
 public string FaxNumber {get;组; 
 
 [StringLength（3）] 
 public string CountryCode {get;组; 
} 
  

如何将其重构为：

  [Table（tblCustomer）] 
 public partial class Customer：Entity 
 {
 [Key] 
 public int CustomerID {get;组; 
 
 [StringLength（10）] 
 public string CustomerCode {get;组; } 
 
 public Address Address {get;组; } 
 
 public Phone Phone {get;组; } 
 
 public Phone Fax {get;组; } 
 
} 
  

不与数据库中已存在的冲突？ / p>

解决方案

您的地址类应该使用 ComplexType 属性注释， d需要明确地列出列名：

  [ComplexType] 
 public class Address 
 {
 [Column（street）] 
 public string Street {get; set;} 
 
 //其他属性
} 
  

I have a class customer that contains address properties, phone properties and fax properties, but I want to take off the address, phone properties to complex types. Does properties are already in the database as columns.

   [Table("tblCustomer")]
public partial class Customer : Entity
{
    [Key]
    public int CustomerID { get; set; }

    [StringLength(10)]
    public string CustomerCode { get; set; }

    [StringLength(60)]
    public string AddressLine1 { get; set; }

    [StringLength(70)]
    public string AddressLine2 { get; set; }

    [StringLength(35)]
    public string City { get; set; }

    [StringLength(2)]
    public string State { get; set; }

    [StringLength(10)]
    public string ZipCode { get; set; }

    [StringLength(15)]
    public string PhoneNo { get; set; }

    [StringLength(3)]
    public string PCountryCode { get; set; }

    [StringLength(3)]
    public string PAreaCode { get; set; }

    [StringLength(7)]
    public string PPhoneNo { get; set; }

    [StringLength(3)]
    public string FCountryCode { get; set; }

    [StringLength(3)]
    public string FAreaCode { get; set; }

    [StringLength(7)]
    public string FaxNumber { get; set; }

    [StringLength(3)]
    public string CountryCode { get; set; }
}

how to refactor this into:

[Table("tblCustomer")]
public partial class Customer : Entity
{
    [Key]
    public int CustomerID { get; set; }

    [StringLength(10)]
    public string CustomerCode { get; set; }

    public Address Address { get; set; }

    public Phone Phone { get; set; }

    public Phone Fax { get; set; }

}

without conflicting with what already exist in the database?

解决方案

Your address class should be annotated with the ComplexType attribute and you'd need to explicitly map the column names:

[ComplexType]
public class Address
{
    [Column("street")]
    public string Street {get; set;}

    // Other properties
}
