Cast Linq query to class that inherit a dictionary

Question

I have a class which inherit a dictionary.

class SymbolsWithQuotes: Dictionary<string, IList<Quotes>> // ex: key: AAPL value: quotations for the last year { // Empty class }

At first, I think its a good idea to inherit a dictionary for readability but now I have a Linq query where I end the statement by:

ToDictionary(x => x.Key, y => y.Value.ArrayObjects() .Select(blabla));

And I have no idea how to cast it to my class SymbolsWithQuotes.

So three questions:

1 / Was is it a good idea to inherit a dictionary for readability ?

2 / Is there a solution to cast my linq query to my object SymbolsWithQuotes

3 / Do you see an alternative solution easier to read and to maintain ? Or should I just use Dictionary> everywhere instead of object SymbolsWithQuotes

Thanks

[Edit] I precise that my linq Query does returns a type

Dictionary<string, IList<Quotes>>

If your SymbolsWithQuotes is nothing but an empty class, then I suggest you not use it. As you've seen, it makes things a bit difficult.

If you just want to create an alias for the name, you could use the using directive:

using SymbolsWithQuotes = Dictionary<string, IList<Quotes>>;
