将列映射到EF Core 3中的子对象

public class Order
{
    public int Id { get; set; }
    public string OrderNumber { get; set; }
    public Address ShippingAddress { get; set; }
}

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string Country { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Order>()
        .OwnsOne(o => o.ShippingAddress, sa =>
        {
            sa.Property(a => a.Street).HasColumnName("ShippingStreet");
            sa.Property(a => a.City).HasColumnName("ShippingCity");
            sa.Property(a => a.Country).HasColumnName("ShippingCountry");
        });
}

public class Order
{
    public int Id { get; set; }
    public string OrderNumber { get; set; }
    [Owned]
    [Column("ShippingStreet")]
    public Address ShippingAddress { get; set; }
}
