用 C# 解析 CSV 文件，带标题 [英] Parsing CSV files in C#, with header

问题描述

是否有默认/官方/推荐的方法来解析 C# 中的 CSV 文件?我不想推出自己的解析器.

Is there a default/official/recommended way to parse CSV files in C#? I don't want to roll my own parser.

此外，我已经看到人们使用 ODBC/OLE DB 通过文本驱动程序读取 CSV 的实例，并且由于其缺点"，很多人不鼓励这样做.这些缺点是什么?

Also, I've seen instances of people using ODBC/OLE DB to read CSV via the Text driver, and a lot of people discourage this due to its "drawbacks." What are these drawbacks?

理想情况下，我正在寻找一种可以通过列名读取 CSV 的方法，使用第一条记录作为标题/字段名称.给出的一些答案是正确的，但基本上可以将文件反序列化为类.

Ideally, I'm looking for a way through which I can read the CSV by column name, using the first record as the header / field names. Some of the answers given are correct but work to basically deserialize the file into classes.

推荐答案

让图书馆为您处理所有细节问题！:-)

Let a library handle all the nitty-gritty details for you! :-)

查看 FileHelpers 并保持干燥 - 不要重复自己 - 无需重新发明轮子无数次....

Check out FileHelpers and stay DRY - Don't Repeat Yourself - no need to re-invent the wheel a gazillionth time....

您基本上只需要通过公共类(以及经过深思熟虑的属性，如默认值、NULL 值的替换等)来定义数据的形状 - CSV 中单独行中的字段)，将 FileHelpers 引擎指向一个文件，然后宾果游戏 - 您可以从该文件中取回所有条目.一个简单的操作 - 出色的性能！

You basically just need to define that shape of your data - the fields in your individual line in the CSV - by means of a public class (and so well-thought out attributes like default values, replacements for NULL values and so forth), point the FileHelpers engine at a file, and bingo - you get back all the entries from that file. One simple operation - great performance!
