Rule Description
Types that define a custom sort order implement the IComparable interface. The CompareTo method returns an integer value that indicates the correct sort order for two instances of the type. This rule identifies types that set a sort order. Setting a sort order implies that the ordinary meaning of equality, inequality, less-than, and greater-than don't apply. When you provide an implementation of IComparable, you must usually also override Equals so that it returns values that are consistent with CompareTo. If you override Equals and are coding in a language that supports operator overloads, you should also provide operators that are consistent with Equals.
