Entity Framework Code First 0 到 1 映射
我想创建这两个模型的地图，如何在代码优先中执行此操作？
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。我正在尝试遵循类似的场景 这个。如果可能的话，我希望能够继承它，例如：
public class PaymentCheque : Payment
{
public int RoutingNumber {get; set;}
}
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;}
}

你真的尝试过吗？或者搜索/谷歌搜索它？
