How do I use the Form's constructor to populate a List Box with data from an Array

Question

How do I use my Form's constructor to populate a Listbox with data from an Array in C#? So far this is what I have in my Name Class

String[,] strSpecialCakeName = {
                               {"Holiday Cake at", "$18"},
                               {"Birthday Cake at", "$25"},
                               {"Wedding Cake at", "$40"},
                               {"Super Hero Cake at", "$30"}
                               };

And this is what I have in my Form

public partial class frmLabSeven : Form
{
    private string[,] strSpecialCakeName = new string[4, 2];

    public frmLabSeven()
    {
        InitializeComponent();

        strSpecialCakeName [0, 0] = "Holiday Cake at $18";
        strSpecialCakeName [1, 1] = "Birthday Cake at $25";
        strSpecialCakeName [2, 2] = "Wedding Cake at $40";
        strSpecialCakeName [3, 3] = "Super Hero Cake at $30";
    }
}

I know I can use the Collection in Item right on the Form, but that is not what I want to do. I just don't know how to get the data to show on the List Box using Arrays.

Answer 1

First thing you need to be aware of is that your array looks like this:

strSpecialCakeName[0,0] = "Holiday Cake at"
strSpecialCakeName[0,1] = "$18"
strSpecialCakeName[1,0] = "Birthday Cake at"
strSpecialCakeName[1,1] = "$25"
strSpecialCakeName[2,0] = "Wedding Cake at"
strSpecialCakeName[2,1] = "$40"
strSpecialCakeName[3,0] = "Super Hero Cake at"
strSpecialCakeName[3,1] = "$30"

You can use a for statement to add it to your listbox:

for (int i = 0; i < 4; i++)
{
    listBox1.Items.Add(strSpecialCakeName[i, 0] + " " + strSpecialCakeName[i, 1]);
}

Answer 2

Iterating through both dimensions would be fairly simple, but I'm not sure it's going to give you what you think it is. Note @Mark Hall comment.

for (int i = 0; i < strSpecialCakeName.GetLength(0); i++)
    lstTest.Items.Add(strSpecialCakeName[i, 0]);
for (int i = 0; i < strSpecialCakeName.GetLength(1); i++)
    lstTest.Items.Add(strSpecialCakeName[0, i]);

Also, note that your assignments in the constructor are going to error due to index being outside the bounds of the declared array.
