Array.Equals is comparing the references, not their contents:
Currently, when you compare two arrays with the = operator, we are really using the System.Object's = operator, which only compares the instances. (i.e. this uses reference equality, so it will only be true if both arrays points to the exact same instance)

If you want to compare the contents of the arrays you need to loop though the arrays and compare the elements.
The same blog post has an example of how to do this.
