跳绳FileHelper列 [英] Skipping a column in FileHelper

问题描述

使用 FileHelper 库的.Net，我可以以某种方式跳过一些列从源文件？

Using the FileHelper library for .Net, can I somehow skip a number of columns from the source file?

根据文档和示例，我要添加字段的所有列。唉，我有一个Excel工作表有216列进口，从少至13是必要的。

According to docs and samples, I have to add fields for all columns. Alas, I have an excel sheet with 216 columns to import, from which as few as 13 are necessary.

推荐答案

我有同样的情况，和问题。搜索论坛在filehelpers.net，我发现这个线程（从2007年？！），与马科斯本人的回应：

I have the same situation, and question. Searching the forums at filehelpers.net, I found this thread (from 2007?!) with a response by Marcos himself:

问：

在一个分隔长的布局，是有可能跳过一些领域？例如：   
ExternalSysId | ExportDate |姓|姓氏   
我只想名字和姓氏，并且不希望扰乱我的code与虚拟字段？

In a delimited length layout, is it possible to skip some fields? For example:
ExternalSysId|ExportDate|FirstName|LastName
I only want FirstName and LastName, and don't want to clutter up my code with "dummy" fields?

响应：

该库没有一个为这个内置的功能。   

可以让私人领域，磁带库将读取的值，但你不要看他们从code =）如果将来需要这些字段可以meke予以公布

The library dont have a built in feature for this.

You can make the fields private, the library will read the values, but you dont see them from your code =) If in the future you need these fields you can meke them public

因此​​，使用记录类向导，以减少所需键入量，然后再作无谓的私人领域，看起来像在这一点上是最好的选择。

So, using the Record Class Wizard to reduce the amount of required typing, and then making unnecessary fields private, looks like the best option at this point.
