Method must have a value return type... though it has one already

Question

I am trying to create a class that contains a header for my list-box. I have two classes that I will be inserting in the listbox. The first class runs fine, but the second one I am making so that the array is entirely of strings is telling me that a method must have a value return type. What does this mean exactly? The error at hand is "HeaderItems."

namespace RETAILITEMSBLAKE
{
class HeaderClass
{
    string HeaderDescription;
    string HeaderPrice;
    string HeaderUnitsonHand;

    public HeaderItems(string HeaderDescription, string HeaderUnitsonHand, string HeaderPrice)
    {
        this.HeaderDescription = HeaderDescription;
        this.HeaderUnitsonHand = HeaderUnitsonHand;
        this.HeaderPrice = HeaderPrice;
    }

    public string HeaderDescriptions
    {
        get
        {
            return HeaderDescription;
        }
        set
        {
            HeaderDescription = value;
        }
    }
    public string HeaderUnits
    {
        get
        {
            return HeaderUnitsonHand;
        }
        set
        {
            HeaderUnitsonHand = value;
        }
    }
    public string HeaderPrices
    {
        get
        {
            return HeaderPrice;
        }
        set
        {
            HeaderPrice = value;
        }
    }
}

Here is my first class that is working correctly:

    namespace RETAILitemsBLAKE
 {
    class ItemizedClass
   {

    string description;
    int unitsonhand;
    double price;

    public ItemizedClass(string description,int unitsonhand,double price)
    {
        this.description = description;
        this.unitsonhand = unitsonhand;
        this.price = price;

    }



    public string Description
    {
        get
        {
            return description;
        }
        set
        {
            description = value;
        }
    }
    public double Price
    {
        get
        {
            return price;
        }
        set
        {
            price = value;
        }
    }
    public int Quantity
    {
        get
        {
            return unitsonhand;
        }
        set
        {
            unitsonhand = value;
        }
    }
}
}

So, my goal is to have the HeaderClass so that I can place them as headers in my Listbox. Is there an alternate way to do such? I want to place it on top of the code here:

   namespace RETAILitemsBLAKE
     {
       public partial class FrmItemList : Form
{

    ItemizedClass[] items;

    public FrmItemList()
    {
        InitializeComponent();
        ItemizedArray();
    }
    private void ItemizedArray()
    {


        ItemizedClass jackets = new ItemizedClass("Jackets", 12, 59.95);
        ItemizedClass jeans = new ItemizedClass("Jeans", 40, 34.95);
        ItemizedClass shirts = new ItemizedClass("Shirts", 20, 24.95);

        items = new ItemizedClass[] { jackets, jeans, shirts };

        foreach (ItemizedClass RetailData in items)
        {
            lstRetailitems.Items.Add(RetailData.Description + "\t\t" + RetailData.Quantity + "\t" + "$" + RetailData.Price);


        }




    }
}
  }

Would anyone be of assistance? Thank you!

Answer 1

You are using construct method which needs as same as class name and it didn't need to set return data type, so the method name needs to write HeaderClass in HeaderClass class otherwise it needs to set return data type to be a normal method.

class HeaderClass
{
    string HeaderDescription;
    string HeaderPrice;
    string HeaderUnitsonHand;

    public HeaderClass(string HeaderDescription, string HeaderUnitsonHand, string HeaderPrice)
