Combine duplicates in a collection of class objects

Hi everyone. Essentially, I need to keep track of the stocks that I've sold each month. To do this, I tried to create a custom class-object to handle the properties of the stock. E.g. what code I've given it, what description it has, and the quantity of it bought by the customer. Here's the class below:

     public class StockItem
     {
         public string Code;
         public string Quantity;
         public string Description;
 
         public StockItem(string code, string qty, string desc)
         {
             Code = code;
             Quantity = qty;
             Description = desc;
         }
     }

I've managed to successfully create a report of each item that I've sold, with its quantity, description and code. However, I would like to know how much of each type of item I've sold over the month, using the code property.

In other words, I have a list of individual items (multiple duplicates) and I want to combine the duplicates into one stock, with the combined quantity. E.g. One customer buys two oranges, and the other buys three oranges. I would like this to just be logged as 5 oranges sold. How exactly would I go about doing this. Thanks.
