If you have your Bitcoins on a paper wallet, it’s a little trickier but it can be done. In this case, I suggest that you set up a wallet on Blockchain.info and link your paper wallet address to this wallet. Then follow the instructions to send to your final destination. Let me know if you need more detailed instructions, and I can walk you through it.
thank you dear, i think you understood. presently my bitcoins are not in a wallet, just have the keys, my adress is valid and confirmed, and i have both public and private key. so it looks like same situation as if i had a paper wallet (?). i think i match with such case.
i fount solution with the help of someone here
solution is :
"Find the Settings on the left part of your screen after logging in on your new blockchain wallet. A small list should open go click addresses then you should find all the addresses there including the import bitcoin address just put the private key there and press import. The request button is beside the send button you can check your imported address there."
