每行包含6个字段。

I need to read about 100 lines of a csv file into memory.

Each line contains 6 fields.

What is the best way to store this into memory and then read it back.

Is a array of a multi- dimsion array the way to do this.

If so I can read the data into an array using an arraylist for each line
and the fields in a string array but cannot see how I can get the data
back out.

Looking forward to comments

推荐答案

您的问题是有问题的，因为它是开放式的主观。什么

做最佳方式对你来说意味着什么？


就个人而言，我会将数据存储在数据表或列表中< twhere t

=强类型类。


Web上有大量样本用于读取和解析CSV文件。

这些包括OLEDB解决方案，正则表达式解决方案和简单的程序
解析。

Your question is problematic because it is open ended and subjective. What
does "Best Way" mean to you?

Personally, I would store the data in either a datatable or list<twhere t
= strongly typed class.

There are a bunch of samples on the web for reading and parsing CSV files.
These include an OLEDB solution, a regex solution, and plain ''ol procedural
parsing.

正确读取CSV文件可能比简单地分割字符串要复杂得多。这是一个优秀的CSV阅读器。

是一个多dimsion数组的数组就是这样做的。

如果是这样的话，我可以使用每行的arraylist和字符串数组中的字段将数据读入数组，但无法看到我如何将数据恢复出来。

它不是读取或写入CSV文件的问题我是

无法找到如何将数据放入多重演示数据的示例，以及如何将数据从arral中取出。


据我所知，我必须使用ArrayList，以便它可以增长动态ly。


问候

杰夫


杰夫写道：

Its not the reading or writing the CSV file which is the issue it is I
cannot find an example of how to place data into a multi-demsendion
array and then how to get the data back out of the arral.

As far as I can see I must use an ArrayList so it can grow dynamically.

Regards
Jeff
