有地址及其扩展<代码>地址应付，它允许您使用本机transfer（）方法将ETH发送到此地址。

由于该类型被称为地址应付，因此您可以通过在类型名称之后附加[]表达式来制作此类型的数组。

没有付款扩展到uint。如果您的目标是定义要发送的金额，则可以存储在常规uint中。

pragma solidity ^0.8;

contract MyContract {
    address payable[] public participants;

    function foo() public {
        uint amount = 1; // 1 wei
        for (uint i = 0; i < participants.length; i++) {
            participants[i].transfer(amount);
        }
    }
}

There's address and its extension address payable, which allows you to use the native transfer() method to send ETH to this address.

Since the type is called address payable, you can make an array of this type by appending the [] expression after the type name.

There's no payable extension to uint. If your aim is to define an amount to be sent, that can be stored in a regular uint.

pragma solidity ^0.8;

contract MyContract {
    address payable[] public participants;

    function foo() public {
        uint amount = 1; // 1 wei
        for (uint i = 0; i < participants.length; i++) {
            participants[i].transfer(amount);
        }
    }
}
