I am trying one Lottery contract in that I am using one function which give me error.

 function pickAWinner() public restricted {
    require(this.balance >= 10 ether);
    uint index = random() % players.length;
    players[index].transfer(this.balance);
    players = new address[](0);
  }

Getting below error, Below error I am getting other contract also as "Member "balance" not found or not visible after argument-dependent lookup in contract" I think there is issue with 'balance' keyword. however I Unable to fixed it.

  Error:-TypeError: Member "balance" not found or not visible after           
  argument-dependent lookup in contract Lottery. Use 
  "address(this).balance" to access this address member.
    require(this.balance >= 10 ether);
            ^----------^

How can I fixed it?

    The error message tells you "use address(this).balance to access this address member." Is there a reason you haven't tried following these instructions? @goodvibration's answer is basically a rephrasing of the error message. – Rosco Kalis Jan 27 at 10:08
