Question

So I have this array

string[,] cars = new String[2, 2] { 
                { "VW Golf GTI", "30000" }, 
                { "Porsche GT3", "300000" }, 
                { "Porsche Cayenne", "80000" }, 
                { "BMW M6", "90000" } 
            };

And want to put everything in a listbox, and I thought this would work, but it doesn’t :/

lstBoxMarket.Items.AddRange(cars);

Now how do I put everything in the listbox in the format

Car – Price ?

Answer 1

Try this:

string[,] cars = new string[4, 2] {
    { "VW Golf GTI", "30000" },
    { "Porsche GT3", "300000" },
    { "Porsche Cayenne", "80000" },
    { "BMW M6", "90000" }
};

for (int i = 0; i < cars.GetLength(0); i++)
{
    lstBoxMarket.Items.Add(cars[i, 0] + " - " + cars[i, 1]);
}

Your version of cars will not currently compile as you are specifying constants for the array initializers (2 rows by 2 columns) but your data has 4 rows.
