Is it possible to extend arrays in C#?

Question

I\'m used to add methods to external classes like IEnumerable. But can we extend Arrays in C#?

I am planning to add a method to arrays that converts it to a IEnumera

Answer 1

static class Extension
{
    public static string Extend(this Array array)
    {
        return "Yes, you can";
    }
}

class Program
{

    static void Main(string[] args)
    {
        int[,,,] multiDimArray = new int[10,10,10,10];
        Console.WriteLine(multiDimArray.Extend());
    }
}
