Join two different string arrays in C#

Question

Hi. I'd like to see if I can join two different string arrays together.

I have these two strings:
string[] AdditionalExtras = new[] { "1 - 16” Alloys", "2 - Privacy Glass", "3 - Spare Wheel", "4 - Parking Pack", "5 - SYNC 3 with Navigation", "6 - Winter Pack", "7 - Floor mats", "8 - Boot liner", "9 - Dashboard camera", "10 - Pet travel mat" }; // Any additional extras will be displayed in the array
string[] ExtrasCost = new[] { "£300", "£250", "£150", "£600", "£600", "£350", "£70", "£61.69", "£284.36", "£264.50" }; // Cost of each extra item

And, I would like them to be displayed like this (if possible):
16” Alloys - £300
Privacy Glass - £250

The prices are already laid out to correspond with each number within the 'AdditionalExtras' array, if that makes sense. So, item 1 will cost £300, item 2 will cost £250 and so on...

To clarify: If the user enters 1 and 2, I would only like those items to be displayed, not the whole list!

I did try to work out a solution on my own, however, nothing I could come with seems to work (my screenshots below should show this). I also looked online for some solutions, but didn't find anything that would've helped me.

Note: I have asked a previous question based on the first array, which can be found here, so I have got the first array working and display how I want to (my code is pretty similar to the answer that was provided).

@Playstation Gamer , Welcome to Microsoft Q&A, based on my test, only a few changes will get what you wanted.

Please change the following code:

while (true)  
            {  
                Console.WriteLine("Please select any of the extras that you would like to purchase!");  
  
                int ExtraSelection = Convert.ToInt32(Console.ReadLine());  
  
                if (dic.ContainsKey(ExtraSelection))  
                {  
                    list.Add(dic[ExtraSelection]+" ---- "+ ExtrasCost[ExtraSelection-1]);// here you need to add  
                }  
                else  
                {  
                    Console.WriteLine("Please input the correct number");  
                }  
                ConsoleKeyInfo c = Console.ReadKey();  
                if (c.Key == ConsoleKey.Spacebar)  
                {  
                    break;  
                }  
  
            }  

Tested result:

Best Regards,
Jack

Answer 2

Try this code:

var result = AdditionalExtras.Zip( ExtrasCost, ( e, c ) => $"{e} - {c}" );

foreach( var r in result )
{
    Console.WriteLine( r );
}

Using arrays is really not the path to take, instead use classes/models e.g. the following is a conceptual starter to expand on as needed. Data should not be stored in code but instead either comma-delimited text file, json file or database.

public class Operations
{
    public static List<Extra> AdditionalItems = new();
    public static string FileName => "TODO";
    public static void Add(Extra sender)
    {
        AdditionalItems.Add(sender);
    }
    public static void Remove(Extra sender)
    {
        AdditionalItems.Remove(sender);
    }

    public static void Clear()
    {
        AdditionalItems.Clear();
    }

    public static void Save()
    {
        // save AdditionalItems if needed using FileName
    }

    public static void ReadFromFile()
    {
        // read from FileName into AdditionalItems
    }
}

public class Extra
{
    public int Id { get; set; }
    public string ItemName { get; set; }
    public decimal Cost { get; set; }
    public int Quantity { get; set; }
    public override string ToString() => ItemName;

}
