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实现？

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。我正在尝试按照this之类的方案。如果可能的话，如果我可以继承这个，我会很高兴，例如：

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