I am slightly confused with meaning of "Joined'. Is it means, you are looking to concatenate the rows or you want to perform Database Join type.
If you are looking for database join, I suggest to use Linq Join method.
If you are looking to merge the both result sets, You can use AddRange() method of List. Get the database records into a generic list and add it to your collection
