Pascal’s triangle use jagged array in C#

class PascalTriangle

    {

        static void Main()

        {

            Console.WriteLine("Enter the row number");

            int Height = int.Parse(Console.ReadLine());

            // Allocate the array in a triangle form

            long[][] triangle = new long[Height + 1][];

            for (int row = 0; row < Height; row++)

            {

                triangle[row] = new long[row + 1];

            }

            // Calculate the Pascal's triangle

            triangle[0][0] = 1;

            for (int row = 0; row < Height - 1; row++)

            {

                for (int col = 0; col <= row; col++)

                {

                    triangle[row + 1][col] += triangle[row][col];

                    triangle[row + 1][col + 1] += triangle[row][col];

                }

            }

            // Print the Pascal's triangle

            for (int row = 0; row < Height; row++)

            {

                Console.Write("".PadLeft((Height - row) * 2));

                for (int col = 0; col <= row; col++)

                {

                    Console.Write("{0,3} ", triangle[row][col]);

                }

                Console.WriteLine();

            }

            Console.ReadLine();

        }

    }
