“Wrong number of indices in side[],expected '2' ” Error

I've been trying to print this code just the way I've written the array, a 3x3 box with numbers that I will later insert into it. All seems correct but I keep getting this message when I try to write my loop:

Cannot implicitly convert type 'int[,]' to 'int[][]' 

 static void Main(string[] args)
        {
            Console.Title = "Quadrado Mágico";
            Console.BackgroundColor = ConsoleColor.DarkCyan;
            Console.Clear();
            Console.ForegroundColor = ConsoleColor.DarkBlue;
            Random ran = new Random();
            Console.Clear();

            int[][] quadrado = new int [3,3] { { 0, 0, 0 }, 
                                         { 0, 0, 0 },
                                         { 0, 0, 0 } };

             for(int fila = 0; fila < quadrado.Length; fila++) {
                for(int coluna = 0; coluna < quadrado[fila].Length; coluna++) {
                 Console.WriteLine(quadrado[fila][coluna] + "\t");
                 }
                Console.WriteLine();
             }


            Console.ReadKey();
        }

    static void Main(string[] args)
    {
        Console.Title = "Quadrado Mágico";
        Console.BackgroundColor = ConsoleColor.DarkCyan;
        Console.Clear();
        Console.ForegroundColor = ConsoleColor.DarkBlue;
        Random ran = new Random();
        Console.Clear();

        const int f = 3;
        const int c = 3;

        int[,] quadrado = new int[f, c]
        {
            {0, 0, 0}, {0, 0, 0}, {0, 0, 0}
        };

        for (int fila = 0; fila < f; fila++)
        {
            for (int coluna = 0; coluna < c; coluna++)
            {
                Console.WriteLine(quadrado[fila, coluna] + "\t");
            }
            Console.WriteLine();
        }


        Console.ReadKey();
    }

This code works. You need to change the int[][] to int[,]

Then you need to use GetUpperBound(0) and (1) to get the length of each of the arrays.

static void Main(string[] args) { Console.Title = "Quadrado Mágico"; Console.BackgroundColor = ConsoleColor.DarkCyan; Console.Clear(); Console.ForegroundColor = ConsoleColor.DarkBlue; Random ran = new Random(); Console.Clear();

        int[ , ] quadrado = new int[3, 3] { { 0, 0, 0 }, { 0, 0, 0 }, { 0, 0, 0 } };

        // ... Loop using the GetUpperBounds.
        for (int fila = 0; fila <= quadrado.GetUpperBound(0); fila++)
        {
            for (int coluna = 0; coluna <= quadrado.GetUpperBound(1); coluna++)
            {
                // Display the element at these indexes.
                Console.WriteLine(quadrado[fila, coluna]);
            }
            Console.WriteLine();
        }
        Console.ReadKey();
    }

Change the following 

 int[][] quadrado = new int [3,3] { { 0, 0, 0 }, 
                                     { 0, 0, 0 },
                                     { 0, 0, 0 } };

to

int[,] quadrado = new int[3, 3] { { 0, 0, 0 }, 
                                     { 0, 0, 0 },
                                     { 0, 0, 0 } };
