NPoco。多对多

Question

我的数据库和C＃模型中都有两个表：

public class Address
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string City { get; set; }
}


public class Customer
{
    public int Id { get; set; }  
    public string FirstName { get; set; }  
    public string LastName { get; set; }
}

我还有一个表，该表将Address和Customer表与列连接起来： Id CustomerId AddressId

如何使用NPoco在表之间实现多对多关系？

Answer 1

使用此示例：

BindingResult

并在模型创建时进行配置：

public class Address
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string City { get; set; }
    public virtual ICollection<CustomerAddress> CustomerAddresses{ get; set; }
}

public class Customer
{
    public int Id { get; set; }  
    public string FirstName { get; set; }  
    public string LastName { get; set; }
    public virtual ICollection<CustomerAddress> CustomerAddresses{ get; set; }
}

public class CustomerAddress
{
    public int CustomerId{ get; set; }
    public int AddressId{ get; set; }

    public virtual Address Address{ get; set; }
    public virtual Customer Customer{ get; set; }
}
