Generic printing of jagged arrays

I am currently working with lots of arrays and for debugging purposes I wrote a generic Print() method to print different kinds of arrays

static void Main()
{
    Print(new double[]{ 1, 2, 3 });

    // Output: [ 1, 2, 3 ]
}

static void Print<T>(T[] array)
{
    int size = array.Length;
    if (size == 0)
        return;

    string str = "[ ";

    for (int i = 0; i < size; i++)
    {
        str += array[i].ToString();

        if (i < size - 1)
            str += ", ";
    }

    str += " ]";

    Console.WriteLine(str);
}

which works fine so far. Then I wanted to print an array of arrays, like double[][], and tried the following:

static void Main()
{
    Print(new double[][]
    {
        new double[] { 1, 2 },
        new double[] { 3, 4 },
        new double[] { 5, 6 },
    });

    // Output: [ 1, 2 ]
    //         [ 3, 4 ]
    //         [ 5, 6 ]
}

static void Print<T>(T[] array)
{
    if (array.Length == 0)
        return;

    if (array[0].GetType().IsArray)
    {
        foreach (var element in array)
        {
            Print<T>(element);
        }
    }
    else
    {
        int size = array.Length;
        string str = "[ ";

        for (int i = 0; i < size; i++)
        {
            str += array[i].ToString();

            if (i < size - 1)
                str += ", ";
        }

        str += " ]";

        Console.WriteLine(str);
    }
}

I just wanted to check if the elements of array again are arrays, and if so, I call the function Print again for each element of array. But Print(element) doesn't work, since element is of type T and not T[] and I don't know how to tell the compiler that in this case T is an array. What do I have to do to make this work?
