C＃优先级队列，通用类型 <T> 转换

Question

public class PriorityQueue<T> : IPriorityQueue<T> 
                            where T : IComparable

So, I've made a priority queue class with the Header above and I'm attempting to use it with another class.

        private static PriorityQueue<Order> PQ;

It seems like this should work perfectly fine, but I'm receiving this error.

My namespace.Order cannot be used as type parameter T in the generic method namespace.PriorityQueue<T> . There is no implicit conversion from namespace.Order to System.IComparable

I can't really discern what that is telling me to do. Does this mean that my IComparable implementation isn't sufficient for this purpose, or is it some sort of bad syntax I'm using?

Answer 1

它说，您的通用类型参数（即Order类型）应实现IComparable接口。
