c# - 使用 for 循环打印相关行的二维数组

Question

I'm writing a C# console app. The "app" is a poor mans matrix (1 and 0 fall down the page).

I can't figure out how to get 1 row first, then two rows (the 1st row should now be in 2cnd place) etc.

The closest I get is just the next row in the 2d array...

This prints just the current row:

    public static int col = 0;

    static void PrintSingleLine()
    {
        for (int i = col; i <= pnms.GetLength(0) - 1;)
        {
            for (int j = 0; j <= pnms.GetLength(1) - 1; j++)
            {
                Console.Write(pnms[col, j]);
            }
            break;
        }
        col =+ 1;
    }

I've modified it, and tried to get it to print out all the rows that have been printed so far +1, but I cant get it to work...

    public static int coll = 0;

    static void PrintRelevantLines()
    {
        int cnt = 0;

        for (int i = coll; i <= pnms.GetLength(0) - 1;)
        {
            for (int j = 0; j <= pnms.GetLength(1) - 1; j++)
            {
                for (int k = cnt; k <= coll; k++)
                {
                    Console.Write(pnms[k, j]);
                }
            }
            break;
        }
        coll = +1;
    }

Any help would be much appreciated.

Thank you

Edit 1:

As requested I will show you the wished for result.

Let's say my array has 3 rows. The values are like this:

 1 0 1 0 0 1 0 1 1 0 1 0 1 0 1 0 0 1 1 1 0 1
 0 1 1 0 1 0 0 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1
 1 0 1 1 0 1 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 1

I would like the 1st second/or user input to print

(x) 1 0 1 0 0 1 0 1 1 0 1 0 1 0 1 0 0 1 1 1 0 1

The 2nd user input to print:

(y) 0 1 1 0 1 0 0 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1
(x) 1 0 1 0 0 1 0 1 1 0 1 0 1 0 1 0 0 1 1 1 0 1

The 3rd user input to print:

(z) 1 0 1 1 0 1 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 1
(y) 0 1 1 0 1 0 0 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1
(x) 1 0 1 0 0 1 0 1 1 0 1 0 1 0 1 0 0 1 1 1 0 1

Thanks for pointing out what wasn't clear. As I posed the question I though that was clear:)

Let me know if I can provide any additional info

Answer 1

You've made things hard for yourself by using j, k, i, etc. - you can make the whole thing easier. I'm assuming you're working off a 2 dimensional array of string. Here's a simpler version (presuming I've understood your requirements correctly...)

static void PrintRelevantLines()
        {
            string [,]  pnms = new string[3,5];
            // Setup data
            pnms[0, 0] = "1";
            pnms[0, 1] = "0";
            pnms[0, 2] = "1";
            pnms[0, 3] = "0";
            pnms[0, 4] = "1";

            pnms[1, 0] = "0";
            pnms[1, 1] = "1";
            pnms[1, 2] = "0";
            pnms[1, 3] = "1";
            pnms[1, 4] = "0";

            pnms[2, 0] = "1";
            pnms[2, 1] = "1";
            pnms[2, 2] = "1";
            pnms[2, 3] = "0";
            pnms[2, 4] = "0";

            for (int columnIndex = 0; columnIndex <= pnms.GetLength(0) - 1; columnIndex ++)
            {
                for (int rowIndex = 0; rowIndex <= pnms.GetLength(1) - 1; rowIndex++)
                {
                        Console.Write(pnms[columnIndex, rowIndex]);
                }

                Console.WriteLine(); // (if you wanted a matrix style trickle of lines, you'd probably want some sort of pause here....)                  
            }

                // OUTPUT
                // 10101
                // 01010
                // 11100
        }

Answer 2

Well, I figured it out. If it helps anyone...

        public static int coll = 0;
        static void PrintRelevantLines()
        {
            Console.Clear();
            if (coll <= pnms.GetLength(0) - 1)
            {
                for (int k = 0; k <= coll; k++)
                {
                    for (int j = 0; j <= pnms.GetLength(1) - 1; j++)
                    {
                        Console.Write(pnms[k, j]);
                    }
                    Console.WriteLine();
                }
            }
