C# print 2D-array in order. Please help!

Question

Hello,

I got a 2-dimentional array containing boolean values written in C#. The cols and rows of the array are to be determined by the user upon creation of the array. I then want to print out the array and it´s containing values onto the console in order.

For example like this, how is this done in C#?

ROWS - COLS - VALUE

---

1 - A - True

1 - B - True

1 - C - True

1 - D - True

---

2 - A - True

2 - B - False

2 - C - False

2 - D - True

---

Answer 1

foreach (Cell[] rows in cells) {
    foreach (Cell c in rows) {
        // print id, c.letter, c.value
    }
}

Answer 2

for (int row = 0; row < array.Length; row++)
{
    Console.WriteLine("--------------------------------");

    for (int col = 0; col < array[row].Length; col++)
    {
        Console.WriteLine("{0} - {1} - {2}", row + 1, 'A' + col, array[row][col]);
    }
}

Something like that.

The idea of this assignment is to learn it yourself. Put some code up of what you've tried first. I really don't think anyone should be answering these kinds of questions unless they have some code already and can't work out where they're going wrong.

Thanks guys! I think I got how it works now so will be moving on. You are as awesome as always.

Take care and if you got your ways past Chicago, I´ll buy you a beer!

Answer 5

Here's is another approach and a complete example. I like working with Lambda but making the first foreach to a lambda aswell wouldn't be very pretty.

var array = new[]
                {
                    new [] { true, false, true, true, false },
                    new [] { false, false, true, false, false },
                    new [] { true, true , true, true, true}
                };

var rowId = 1;
var colId = 0;

foreach (var row in array)
{
    row.ToList().ForEach(value => Console.WriteLine(
         string.Format("{0} - {1} - {2}", rowId, (char)('A' + colId++), value)));

    rowId += 1;

    Console.WriteLine("--------------------------");
}

Will output the following:

1 - A - True
1 - B - False
1 - C - True
1 - D - True
1 - E - False
--------------------------
2 - A - False
2 - B - False
2 - C - True
2 - D - False
2 - E - False
--------------------------
3 - A - True
3 - B - True
3 - C - True
3 - D - True
3 - E - True
--------------------------
