程序操作上的理解：
值對(duì)象不需要在DbContext里面寫DbSet，比如Address是值對(duì)象，不需要在DbContext里面寫 public DbSet<Address> Addresss { get; set; }

//值對(duì)象(不需要有主鍵)
public class Address
{
    #region Properties
    // 國(guó)家
    public string Country { get; set; }

    //省份
    public string State { get; set; }

    // 市
    public string City { get; set; }

    public string Street { get; set; }

    public string Zip { get; set; }

    #endregion
}

使用值對(duì)象的領(lǐng)域：

public class User:AggregateRoot
{
    public string UserName { get; set; }
    public string Password { get; set; }

    public string Email { get; set; }

    public string PhoneNumber { get; set; }

    public bool IsDisabled { get; set; }

    public DateTime RegisteredDate { get; set; }

    public virtual Address UserAddress { get; set; }//值對(duì)象
}

生成的數(shù)據(jù)表會(huì)是：
