C# sorting arrays in ascending and descending order

Question

I\'m having trouble writing a method that returns true if the elements of an array (numbers) are in sorted order, ascending or descending, and false, if they are not in any

Answer 1

Using Linq -

public static bool IsArraySorted(int[] numbers)
{
    var orderedAsc = numbers.OrderBy(a => a);
    var orderedDes = numbers.OrderByDescending(a => a);

    bool isSorted = numbers.SequenceEqual(orderedAsc) ||
                    numbers.SequenceEqual(orderedDes);
    return isSorted;
}
