在C＃中解析CSV文件，带头 [英] Parsing CSV files in C#, with header

问题描述

有没有默认/官方/推荐的方式来解析C＃中的CSV文件？我不想卷自己的解析器。

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

此外，我看到一些人使用ODBC / OLE DB通过文本驱动程序读取CSV，很多人由于其缺点而沮丧。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，我正在寻找一种通过列名读取CSV的方法，使用第一个记录作为标题/字段名。

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

让一个库处理所有的nitty-细腻的细节为你！ ： - ）

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

查看 FileHelpers 并保持DRY - 不要重复自己 - 不需要重新发明轮子一个gazillionth时间....

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

你基本上只需要定义你的数据的形状 - 字段在CSV中的单独行中 - 通过公共类（以及精心设计的属性，如默认值，NULL值的替换等等），将FileHelpers引擎指向一个文件，bingo - 返回所有来自该文件的条目。一个简单的操作 - 伟大的性能！

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!
