界定一般类型:
public class Point<T> where T : IConvertible, IComparable
我确实想做的是,将T限制为一种数字类型(即斜体或浮标)。 在《刑法》中没有任何名词。 是否有接口或接口收集,可以在此用来将类型限制在盒式数字类别之一?
不幸的是,没有。 这一直是。
如今,最佳选择有可能使用:
where T : struct, IConvertible, IComparable<T>
(结构限制阻止使用......)
然而,这仍然允许任何用户确定的价值类型,以实施适当的限制。
<代码>T: 指示将限制其为价值类型。
一种——不十分舒适的方式——是检查建筑商的有效类型,并作出例外规定。 它是“比较-安全”的,会产生错误。
No you can t do it.
You can choose where T:struct,IConvertible,IFormattable,IComparable to restrict it to all blittable numeric types and enums, but even if you did the restriction you still can t use operators on T as the operators are all static.
E.g.
point.X-point.Y
这将是非法的,因为普通人不知道固定成员。
