[Contract] Solidity address payable 轉換與數組地址

 

address payable  -->  address

address payable addr1 = msg.sender;

address addr2 = addr1; // 隱式轉

address addr3 = address(addr1); // 顯式轉

 

address  -->  address payable

address addr1 = msg.sender;

address payable addr2 = address( uint160(addr1) ); // 須要先通過uint160

 

普通數組地址是：address[]，可支付數組地址是：address payable[]
