Display list and its items, also display items counts-CodePudding

"I want to display the list Categoty and its items count"

Here i have both the List and the Dictionary

 public static List<Category> categories = new List<Category>();
 public static Dictionary<string, ProductInfo> ProductInformation = new Dictionary<string, ProductInfo>();

Here are the AddProduct method

static Dictionary<string, ProductInfo> ProductDictionary { get; } = new Dictionary<string, ProductInfo>();
        
static void AddProduct(ProductInfo product)
            {


    var productExist = ProductDictionary.Any();


    if (!productExist)
    {
       // Add product to list

    }
    else
    {

        // Throw an ArgumentException

    }

}

Problem : i want to display the categories made and the count of its products using this code:

static void ShowCategory()
    {
        foreach (var c in Category.categories)
            Console.WriteLine(ProductDictionary[c.Name].Count);

        Console.ReadKey(true);
        ConsoleKey key = ConsoleKey.Escape;
    }

I get an error that says:

CS1503: cannot convert from 'method group' to 'bool'

What does that mean?

I means exactly what it says. In your case Count is a method and not a property as you expect it to be. Change your code to:

Console.WriteLine(ProductDictionary[c.Name].Count());
