在你的代码中,你没有包含 `<sstream>` 头文件,导致 `stringstream` 类型无法使用。你需要添加以下代码来包含 `<sstream>` 头文件:
```cpp
#include <sstream>
```
此外,你还需要使用 `std::vector<Member>` 来存储读取到的成员数据。在 `while` 循环中,你可以创建一个新的 `Member` 对象,并将其添加到 `members` 向量中。修改后的代码如下所示:
```cpp
#include<iostream>
#include<fstream>
#include<vector>
#include<sstream>
using namespace std;
class Member {
public:
string studentID;
string name;
string department;
string grade;
string group;
string position;
Member(string id, string n, string dept, string grd, string grp, string pos) {
studentID = id;
name = n;
department = dept;
grade = grd;
group = grp;
position = pos;
}
};
void readFromFile() {
ifstream file("members.txt");
if (file.is_open()) {
string line;
vector<Member> members; // 用于存储成员数据的向量
while (getline(file, line)) {
stringstream ss(line);
string studentID, name, department, grade, group, position;
ss >> studentID >> name >> department >> grade >> group >> position;
Member member(studentID, name, department, grade, group, position);
members.push_back(member); // 将成员对象添加到向量中
}
file.close();
cout << "人员数据读取成功" << endl;
// 在此处可以使用 members 向量进行进一步处理或存储
}
else {
cout << "读取文件失败" << endl;
}
}
```
这样就可以正确地读取文件并将成员数据存储到 `members` 向量中。
