Solidity中uint数组push结构体实例报错Member 'Push' not found求助

核心错误是数组类型与要添加的元素类型不匹配：

• IntArrayTest被声明为uint[]（uint类型数组），但你在addElements方法里尝试向它push一个Numbers结构体实例，Solidity不允许跨类型的数组元素添加，因此触发Member 'Push' not found错误（本质是类型不兼容导致push方法无法识别该操作）。

根据你的需求，有两种修正方式：

方式一：将数组改为结构体类型 #

如果你确实需要用Numbers结构体存储数值，把IntArrayTest的类型修改为Numbers[]即可：

pragma solidity ^0.8.7;

contract MyTestContarct{
    Person[] public people;

    uint256 public peopleCount;

    struct Person {
        string _firstName;
        string _lastName; 
    }

    function addPerson(string memory _firstName, string memory _lastName) public{   
        people.push(Person(_firstName, _lastName));
        peopleCount +=1;
    }

    // 修改为Numbers结构体数组
    Numbers[] IntArrayTest;

    uint256 public elementsCounter;

    struct Numbers{
        uint _number;
    }
    

    function addElements(uint _number) public{
        IntArrayTest.push(Numbers(_number));
        elementsCounter +=1;
    }
} 

方式二：简化为直接存储uint值 #

如果Numbers结构体仅用来存储单个uint数值，完全可以省略结构体，直接向uint[]数组push数值：

pragma solidity ^0.8.7;

contract MyTestContarct{
    Person[] public people;

    uint256 public peopleCount;

    struct Person {
        string _firstName;
        string _lastName; 
    }

    function addPerson(string memory _firstName, string memory _lastName) public{   
        people.push(Person(_firstName, _lastName));
        peopleCount +=1;
    }

    uint[] IntArrayTest;

    uint256 public elementsCounter;
    

    function addElements(uint _number) public{
        IntArrayTest.push(_number);
        elementsCounter +=1;
    }
}
