实体框架代码先0到1映射

本文关键字：映射 框架 代码 实体 | 更新日期: 2023-09-27 17:50:30

我想创建这2个模型的映射，我如何在代码优先中做到这一点?

public class Payment
{
    public int PaymentId { get; set; }
}
public class PaymentBank
{
    public int PaymentId { get; set; }
}
public class PaymentCheque
{
    public int PaymentId { get; set; }
}

Payment可以是PaymentBank或PaymentCheque类型。我在试着模拟这样的场景。如果可能的话，我希望可以继承这个，比如:

public class PaymentCheque : Payment
{
    public int RoutingNumber {get; set;}
}

您可以查看以下三篇文章，它们专注于在Entity Framework Code-First中实现继承:

你真的试过吗?或者搜索/谷歌一下?
