Answer 1

We can define the jagged arrays as the following code without exception.

 static void Main(string[] args)
        {
            int[][] jaggedarr = new int[1][];
            jaggedarr[0] = new int[0];
            jaggedarr[0] = new int[] { 25};
            Console.WriteLine(jaggedarr[0][0]);
            Console.ReadKey();
        }

Result:

Answer 2

jaggedarr[0] = new int[0];

this creates a list with zero size. You want a list of size 1.
