实体框架代码第一个0到1映射

Question

我想创建这两个模型的地图,我该如何在代码优先？

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可以是类型PaymentBank或PaymentCheque.我试图按照类似的情景这样.如果可能的话,如果我能继承这个,我会很高兴,例如:

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

您可以查看以下三篇文章，重点介绍在实体框架代码优先中实现继承：
