Inheriting from Array class

Question

All arrays i create in C# inherit implicitly from the Array class. So why are methods like Sort() etc not available to the array i create. For example, consider the following code:

int [] arr = new int[]{1,2,3,4,5};

Console.WriteLine(arr.Length); //This works,Length property inherited from Array

Array.Sort(arr); //Works

arr.Sort(); //Incorrect !

Please Help Thank You.

It's because the Sort method is a static method defined on the Array class so you need to call it like this:

Array.Sort(yourArray);

You don't need an instance of the class to call a static method. You directly call it on the class name. In OOP there's no notion of inheritance for static methods.
