Question

我想将客户插入我的mongodb。我有一个Customer类和一个Address值对象。目前它不保存客户的地址，除非我将属性BsonElement放在Address的属性中。

我不想使用这个“BsonElement”属性我的“域名”还有其他选项吗？

我考虑过创建一个DTO，但我想要更容易一些。

这是我的代码：

客户类：

public class Customer : Entity<Customer>
{
    public Customer(string firstName, string lastName, string phoneNumber, Address address, IUser user)
    {
        FirstName = firstName;
        LastName = lastName;
        Address = address;
        User = user;
        PhoneNumber = new PhoneNumber(phoneNumber);

    }
    public string FirstName { get; protected set; }

    public string LastName { get; protected set; }

    public Address Address { get; protected set; }

    public PhoneNumber PhoneNumber { get; protected set; }

    public IUser User { get; protected set; }

    public bool ChangeName(string firstName, string lastName)
    {
        if (firstName == this.FirstName &&
            lastName == this.LastName)
        {
            return false;
        }

        this.FirstName = firstName;
        this.LastName = lastName;

        Validations.Update("FirstName", this);
        Validations.Update("LastName", this);

        AddEvent(new CustomerNameChanged(Id, firstName, lastName));

        return true;
    }

    public bool ChangeAddress(Address address)
    {
        if (Address == address)
        {
            return false;
        }

        this.Address = address;

        Validations.Update("Address", this);

        AddEvent(new CustomerAddressChanged(Id, Address));

        return false;
    }

    public bool ChangePhoneNumber(string phoneNumber)
    {
        var newPhoneNumber = new PhoneNumber(phoneNumber);
        if (newPhoneNumber == PhoneNumber)
        {
            return false;
        }

        this.PhoneNumber = PhoneNumber;

        AddEvent(new CustomerPhoneChanged(Id, PhoneNumber.Number));

        return true;
    }

}

地址类：

public class Address : ValueObject<Address>
{
    public Address(string addressLine1, string addressLine2, string city, string state, string zipCode)
    {
        AddressLine1 = addressLine1;
        AddressLine2 = addressLine2;
        City = city;
        State = state;
        ZipCode = zipCode;
    }


    public string AddressLine1 { get; }

    public string AddressLine2 { get; }

    public string City { get; }

    public string State { get; }

    public string ZipCode { get; }

    public override bool Equals(ValueObject<Address> other)
    {
        var address = other as Address;
        return address != null &&
               AddressLine1 == address.AddressLine1 &&
               AddressLine2 == address.AddressLine2 &&
               City == address.City &&
               State == address.State;
    }

}

插入方法：

public void Insert(Customer customer)
{
        _mongoDatabase
            .GetCollection<Customer>("Customers")      
            .InsertOne(customer);
}

我必须为我的客户和地址注册地图。

客户地图注册：

 BsonClassMap.RegisterClassMap<Customer>(m =>
        {
            m.MapField(x => x.FirstName);
            m.MapField(x => x.LastName);
            m.MapField(x => x.LastName);
            m.MapField(x => x.PhoneNumber);
            m.MapField(x => x.Address);
            m.MapField(x => x.User);
        });

地址地图注册：

BsonClassMap.RegisterClassMap<Address>(m =>
        {
            m.MapField(x => x.AddressLine1);
            m.MapField(x => x.AddressLine2);
            m.MapField(x => x.City);
            m.MapField(x => x.State);
            m.MapField(x => x.ZipCode);
        });

我在Startup.cs上调用所有地图，它有效。
