C# loop over an array of unknown dimensions

Question

I want to create an extension method to loop over System.Array with unknown number of dimensions

For now I am using a naive approach:

If you don't care about the indices, you can just iterate over a System.Array with absolutely no knowledge of its Rank. The enumerator will hit every element.

public class Program
{
    public static void IterateOverArray(System.Array a)
    {
        foreach (var i in a)
        {
            Console.WriteLine(i);
        }
    }

    public static void Main()
    {
        var tests = new System.Array []
        {
            new int[] {1,2,3,4,5,6,7,8},
            new int[,]
            {
                {1,2},{3,4},{5,6},{7,8}
            },
            new int[,,]
            {
                {  {1,2},{3,4} },
                {  {5,6},{7,8} }
            }
        };


        foreach (var t in tests)
        {
            Console.WriteLine("Dumping array with rank {0} to console.", t.Rank);
            IterateOverArray(t);
        }
    }
}

Output:

Dumping array with rank 1 to console.
1
2
3
4
5
6
7
8
Dumping array with rank 2 to console.
1

8
Dumping array with rank 3 to console.
