Aproducts.ToDictionary(p => p.Name, p => p.Price).Where(p => p.Value > 50);

Bproducts.Where(p => p.Price > 50).ToDictionary(p => p.Name, p => p.Price);

Cproducts.Select(p => new {p.Name, p.Price > 50}).ToDictionary(p => p.Name, p => p.Price);

Dproducts.Where(p => p.Price > 50).Select(p => p.Name).ToDictionary();
