输入文件读数只需重复2个文件中的1个数据行

Question

我正在从事一个项目。这个想法是它有两个输入文件，我们将其称为TimeFile和fullfile。

timefile给出了格式的两个时间戳：

DD-MM-YY HH:MM:SS     DD-MM-YY HH:MM:SS

fullfile以时间戳的格式和一些数据：

YYYY-MM-DD HH:MM:SS   Value    Error    Error

这个想法是该程序从timefile timefile < /code>，然后浏览fullfile中的所有行，如果它从fullfile中找到一个时间戳，该时间戳从timefile中降落在两个之间将整行复制到一个新的较小数据文件中。从本质上讲，我想从一个巨大的数据文件到一堆较小的数据文件，除以时间间隔。

不用说，它行不通。它可以完成我想要的大部分内容，但是所产生的较小数据文件始终是空的。

奇怪的部分是原因。它似乎可以从timefile读取时间戳，但是它会从fullfile中弄清楚读数，然后一遍又一遍地读取第一行。我真的没有一个扎实的想法，为什么我能确定的是他们以同样的方式阅读，但是一个作品，另一个作品却没有。

我很难过，任何帮助都将不胜感激。

编辑：认为，如果我给出每个数据文件的几行以查看是否是格式化问题，这可能会有所帮助，因此，这是每条数据的前3行：

TimeFile

03-Apr-22 22:42:19  03-Apr-22 22:56:13
03-Apr-22 22:58:25  03-Apr-22 23:15:14
03-Apr-22 23:17:23  03-Apr-22 23:35:32

Fullfile

2022-04-13 12:39:37.500000000   70.00000    0.0 0.0
2022-04-13 12:43:52.500000000   70.00000    0.0 0.0
2022-04-13 12:48:07.500000000   70.00000    0.0 0.0

Edit2： - 重要发现。用该块未注销的块运行此代码会重现该行中的数据，但没有70 0 0，您可以在最后三个值中获得1 0 43.1495。 Getline似乎没有这样做，但是我很难理解如何切开这一开放。

不完全确定这是什么意思，除了以某种方式无法正确读取这些值，但是当我尝试考虑一个标签时，这并不是一个改进。
