实体框架代码第一个0到1的映射

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PaymentBank型或PaymentCheque的。我试图按照如this的方案。如果可以的话，我愿意继承，如：

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