Product[] inventoryProducts = new Product[100];

I was asked to create a 10 row structure array for displaying, updating, reading, and writing info to update a txt file, but with this example code given to me, I keep receiving an error that says "Error CS0246 The type or namespace name 'Product' could not be found (are you missing a using directive or an assembly reference?)" I am so lost with these arrays

addtional info: this is a class level array, and this is a windows forms application

Figured it out in case anyone wants to know...

        struct Product
    {
        public string ProdId;
        public string ProdName;
        public string ProdDesc;
        public int ProdQuantityOnHand;
        public int ProdReorderQuantity;
        public decimal ProdPrice;
    }

    //create a 10 row array of Products:
    Product[] allProducts = new Product[10];
    int arrayIndex = 0;

If you hover above the Error they give you possible solution. Could you maybe just add the directory? Or is the Class set private?

CodePudding user response：

This is how you declare an array in C#. You also need to fill it up afterwards.

/// <summary>
/// Defines a product
/// </summary>
public class Product
{
    public Product(string name, string vendor, decimal price)
    {
        Name=name;
        Vendor=vendor;
        Price=price;
    }

    public string Name { get; }
    public string Vendor { get; set; }
    public decimal Price { get; set; }
}

static class Program
{
    static void Main(string[] args)
    {
        Product[] array = new Product[10];
        // array of 10 items (rows) is declared, but it is empty:
        // array[0] = null;
        // array[1] = null;
        // ..

        // Fill the array
        array[0] = new Product("PIN", "A", 0.06m);
        array[1] = new Product("PEN", "A", 0.86m);
        array[2] = new Product("PAN", "B", 8.12m);
        // ..
        // etc
    }
}
