SortedSet<T>.CreateSetComparer Method ()
Returns an IEqualityComparer object that can be used to create a collection that contains individual sets.
Assembly: System (in System.dll)
The IEqualityComparer object checks for equality at only one level; however, you can chain together comparers at additional levels to perform deeper equality testing.
Calling this method is an O(1) operation.
