mfc读取txt文件一列数据到double数组中

    CString filepath;
    filepath = "C:\\Users\\Administrator\\source\\repos\\MFCApplication8\\Debug\\data.txt";
    std::vector m_data;
    CStdioFile m_file(filepath, CFile::modeRead);
    CString contents;
    while (m_file.ReadString(contents))
    {
        double temp = 0.0;
        //CString转换成double会有误差

        temp = (float)_ttof(contents);
        m_data.push_back(temp);
    }
