wrong number of indices inside []; expected 2

public static void Main(string[] args)
{
    int width;
    int height;

    Console.WriteLine("Please enter the width of the array");
    width = Convert.ToInt32(Console.ReadLine());

    Console.WriteLine("Please enter the height of the array");
    height = Convert.ToInt32(Console.ReadLine());

    int[,] grid = new int [width,height];

    for(int x = 0; x < width; x++)
    {
        for(int y = 0; y < height; y++)
        {
            Console.WriteLine(grid[x][y]);
        }
    }

Just to be clear i am a beginner, and all the other answers are either way too complex or i just straight up cant understand them. the line in which i am getting the error is this:

int[,] grid = new int[width, height];

Use Console.WriteLine(grid[x, y]); instead of Console.WriteLine(grid[x][y]);

You're mixing up multidimensional arrays and jagged arrays. Multidimensional arrays are always rectangular1, and are indexed by multiple indices inside a single indexer:

grid[x,y]

Jagged arrays are arrays of arrays, and are not necessarily rectangular. You access an element by indexing into the outer array with one indexer, and then using a second indexer to access the element:

grid[x][y]

In your case, you've created a multidimensional array - you need to use the first syntax.

1Or whatever the appropriate term is with a higher number of dimensions.
