[Contract] Solidity address payable 转换与数组地址

address payable  -->  address

address payable addr1 = msg.sender;
 
address addr2 = addr1; // 隐式转
 
address addr3 = address(addr1); // 显式转

address  -->  address payable

address addr1 = msg.sender;
 
address payable addr2 = address( uint160(addr1) ); // 需要先经过uint160

普通数组地址是：address[]，可支付数组地址是：address payable[]
