I need to determine whether or not two sets contains exactly the same elements. The ordering does not matter.
For instance, these two arrays should be considered equal:
IEnumerable<int> data = new []{3, 5, 6, 9};
IEnumerable<int> otherData = new []{6, 5, 9, 3}
One set cannot contain any elements, that are not in the other.
Can this be done using the built-in query operators? And what would be the most efficient way to implement it, considering that the number of elements could range from a few to hundreds?
