c++ 获取硬盘序列号

可以使用Windows API函数`GetVolumeInformation()`获取硬盘的卷标和序列号。以下是一个示例代码：

#include <Windows.h>
#include <iostream>
#include <string>

int main() {
    char volume[MAX_PATH + 1] = { 0 };
    char fs[MAX_PATH + 1] = { 0 };
    DWORD serial = 0;
    DWORD maxComponentLen = 0;
    DWORD fileSystemFlags = 0;

    std::string driveLetter = "C:"; // 要获取序列号的硬盘盘符

    BOOL ok = GetVolumeInformation(
        driveLetter.c_str(),
        volume,
        MAX_PATH,
        &serial,
        &maxComponentLen,
        &fileSystemFlags,
        fs,
        MAX_PATH
    );

    if (ok) {
        std::cout << "Volume: " << volume << std::endl;
        std::cout << "Serial number: " << std::hex << serial << std::endl;
    }
    else {
        std::cout << "Failed to get volume information. Error code: " << GetLastError() << std::endl;
    }

    return 0;
}

需要注意的是，获取硬盘序列号需要管理员权限。
