本文深入探讨了IComparable和IComparer在C#中的应用，解释了它们如何为自定义类型提供排序机制。IComparable适用于定义类型的自然排序，而IComparer则用于提供替代排序或为不支持排序的类型添加排序能力。

IComparable and IComparer are the standard mechanisms for providing ordering relations for your types. IComparable should be used for the most natural ordering. When you implement IComparable, you should overload the comparison operators (<, >, <=, >=) consistently with our IComparable ordering. IComparable.CompareTo() uses System.Object parameters, so you should also provide a type-specific overload of the CompareTo() method. IComparer can be used to provide alternative orderings or can be used when you need to provide ordering for a type that does not provide it for you.
