Check out example codes for "copy 2d arrays C#". It will help you in understanding the concepts better.

Code Example 1

public char[,] arrayCopy(char[,] input)
    {
        char[,] result = new char[input.GetLength(0), input.GetLength(1)]; //Create a result array that is the same length as the input array
        for (int x = 0; x < input.GetLength(0); ++x) //Iterate through the horizontal rows of the two dimensional array
        {
            for (int y = 0; y < input.GetLength(1); ++y) //Iterate throught the vertical rows, to add more dimensions add another for loop for z
            {
                result[x, y] = input[x, y]; //Change result x,y to input x,y
            }
        }
        return result;
    }
