Question

我想将单个参数作为数组传递给函数调用：

contract MyToken is StandaloneERC20 {

    function initialize(
        address owner,
        address minter,
        address[] memory pausers
    ) public initializer {

        address[] memory minters = [minter];

        StandaloneERC20.initialize("MyToken", "MTK", uint8(18), minters, pausers);
    }

StandaloneERC20.initialize期望第四个参数minters的数组：

function initialize(
    string memory name, string memory symbol, uint8 decimals, address[] memory minters, address[] memory pausers
) public initializer {

但是，使用我的代码，我得到了稳定度为0.5.7的以下编译器错误：

TypeError: Type address[1] memory is not implicitly convertible to expected type address[] memory.

    address[] memory minters = [minter];
    ^---------------------------------^

我也试图将miner作为数组参数传递：

contract MyToken is StandaloneERC20 {

    function initialize(
        address owner,
        address minter,
        address[] memory pausers
    ) public initializer {

        StandaloneERC20.initialize("MyToken", "MTK", uint8(18), [minter], pausers);
    }

但是由于此编译器错误，这似乎与我的预期完全不同：

Member "initialize" not found or not visible after argument-dependent lookup in type(contract StandaloneERC20).
        StandaloneERC20.initialize("MyToken", "MT", uint8(18), [minter], pausers);
        ^------------------------^

这是一种使用单个参数声明数组的方法

以下是contract MyToken is StandaloneERC20 { function initialize( address owner, address minter, address[] memory pausers ) public initializer { address[] memory minters = new address[](1); minters[0] = minter; StandaloneERC20.initialize("MyToken", "MTK", uint8(18), minters, pausers); } }个关于Allocating Memory Arrays的文档
