Is it necessary to export/import wallet to get the private key

[raythunder]

Dear all,

I'm just download the Bitcoin.com wallet and successful withdraw BTC from Exchange into the wallet (after Backup), but the Bitcoin Wallet guide did advise us in order to the get private key we need to Export and Import things, but as I follow the instruction and finally import this things, the wallet pop-up said, I had my wallet import in place but I had no clue to find the private key. Could anyone guide me on this?

Many thanks
