Does not contain a constructor that takes 0 arguments

Question

I get an error stating "Products does not contain a constructor that takes 0 arguments" from the following code:

public class Products
{
    string          


        

Answer 1

Since Products has no constructor that takes 0 arguments, you must create a constructor for FoodProducts that calls the constructor of Products will all the required arguments.

In C#, this is done like the following:

public class FoodProducts : Products
{

    public FoodProducts(string id, string name, double price, int soldCount, int stockCount, double tax)   
    : base(id, name, price, soldCount, stockCount, tax)
    {
    }

    public void Limit()
    {
        Console.WriteLine("This is an Attribute of a Product");
    }
}

If you don't want to add this constructor to FoodProducts, you can also create a constructor with no parameter to Products.
