    private ProductsEntities products = new ProductsEntities();
     public IEnumerable<ProductTable> GetAllProdcuts()

        return products.ProductTables.AsEnumerable();
    }

Answer 1

you can use Where extension method that takes an expression as parameter to filter out the return objects.

private ProductsEntities products = new ProductsEntities();
public IEnumerable<ProductTable> GetAllProdcuts()
{
    return products.ProductTables.Where(x=>x.Price>firstPrice && x.Price<secondPrice).AsEnumerable();
}
