How do i calculate the following bolded items below to create a total of all items in a text file? invoices.Add(counter + "," + freshGrocery.Name + "," + freshGrocery.Price + "," + freshGrocery.Weight); invoices.Add(counter + "," + grocery.Name + "," + price + "," + grocery.Quantity);
full code below. Not sure how to add int from different strings
