我必须制作一个c＃程序，它将读取文本文件并提取所需的数据并创建数据库。文本文件将类似于下面的示例，这只是一个类别国家结果，在国家之后是区域结果，并且对于每个区域都有所有选举位置。所有这些都在同一个文本文件中。我如何阅读这样的大型文本文件，程序可以了解其国家，地区或位置是否采用所有值，以及带有值的名称并将其存储在相应的数据库中？我是新手，我已经编写了一些代码，但是它逐行读取。因此，如果文件中添加了1行，则程序将无法正确读取。
现在我试图找到一种方法来提取我需要的数据。这不完全是文件的方式，因为我不能包含真实数据及其在希腊语中。但是你明白了，现在我只是逐行阅读。但是txt文件必须始终与使用这种方式编写的方式完全相同，以便获得数据的相关性。因为我是2个月的编程新手，所以这是一项非常艰巨的任务：）
