实体框架代码第一个0到1映射

Question

I want to create a map of these 2 models, how do I do this in code-first?

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 can be either of type PaymentBank or PaymentCheque . I'm trying to follow a scenario like this . I'd love if I could do inheritance of this if possible, such as:

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