For this program i've asked the user to input the array size then its filled with numbers in chronological order until the array is full. I Want to then put this array into the grid. I was wondering if it's possible to start the input of the array at a certain point, say its was the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 10. Would i be able to start the input at a certain point like [0,2], so basically not use the first slots to make the grid like;

[] [] [1] [2] [3]
[4] [5] [6] [7] [8]
[9] [10] [] [] []

i was wondering if and how i would be able to do this Thank you in advance!

C#

class Program
{
      static void Main(string[] args)
      {

        int Height = 4;
        int Width = 5;

        int[,] grid = new int[Height, Width];

        Console.Write("Input Number: ");
        int number = int.Parse(Console.ReadLine());
        int[] InputNumber = new int[number];
        var randomNumbers = Enumerable.Range(1, number).ToArray();

        /*
        [0,0] [0,1] [0,2] [0,3] [0,4]
        [1,0] [1,1] [1,2] [1,3] [1,4] 
        [2,0] [2,1] [2,2] [2,3] [2,4] 
        [3,0] [3,1] [3,2] [3,3] [3,4]*/

    }
}

What I have tried:

i'm new to c# programming and i've tried just about everything, spending so many hours in the process trying to figure it out myself as well as researching,however i can't find anything.

Yes. You can.
How would you do it with a deck of cards?

if don not want to use first some slots then initialize them with some unique number like -999 or 0. Because i think u cant left it as blank if its integer array.

This is not only not the answer but it is wrong in so many other ways!!!

I made this example, hope it helps:

C#

static void Main(string[] args)
{

    int Height = 4;
    int Width = 5;

    Console.Write("Height: ");
    Height = int.Parse(Console.ReadLine());

    Console.Write("Width: ");
    Width = int.Parse(Console.ReadLine());

    int[,] grid = new int[Height, Width];

    //TEst
    PrintGrid(grid, Height, Width);
    //Console.ReadLine();

    //Console.Write("Input Number: ");
    Console.Write("Input Number of Start SLOT between 1 and " + (Height * Width) + ": ");
    int startSlot = int.Parse(Console.ReadLine());

    Console.Write("Input Number. How many SLOT to fill between 1 and " + ((Height * Width) -startSlot+1) + ": ");
    int numberSlot = int.Parse(Console.ReadLine());

    ///int[] InputNumber = new int[numberSlot];
    //var randomNumbers = Enumerable.Range(1, number).ToArray();
    //grid[0, 2] = randomNumbers[0];//Put direct in the position

    //Randoms numbers to insert
    int[] numbers = new int[numberSlot];
    Random randNum = new Random();
    for (int i = 0; i < numberSlot; i++)
    {
        numbers[i] = randNum.Next(1, (Height * Width));
    }

    //Insert from the start position
    int pos = 0;
    int numberIndex = 0;
    for (int i = 0; i < Height; i++)
    {
        for (int j = 0; j < Width; j++)
        {
            //ACTUAL POSITION
            pos++;
            if (pos == startSlot || pos > startSlot) {
                if (numberIndex < numberSlot) {
                    grid[i, j] = numbers[numberIndex];
                    numberIndex++;
                }
            }
        }
    }

    PrintGrid(grid, Height, Width);
    Console.ReadLine();
    /*
    [0,0] [0,1] [0,2] [0,3] [0,4]
    [1,0] [1,1] [1,2] [1,3] [1,4]
    [2,0] [2,1] [2,2] [2,3] [2,4]
    [3,0] [3,1] [3,2] [3,3] [3,4]*/

}

static void PrintGrid(int[,] grid,  int h,int w) {
    Console.Write("\nPrint Grid\n");
    for (int i = 0; i< h; i++) {
        for (int j = 0; j < w; j++) {
            Console.Write( (grid[i, j]).ToString() + " ");
        }
        Console.Write("\n");
    }
}
