IFilter的或SDK的多种文件类型？ [英] IFilter or SDK for many file types?

问题描述

有谁知道一个API / SDK或IFilter的.NET中，可以读取以下文件的主题（标题元数据）和文字：

Does anybody know of an API/SDK or IFilter in .NET that can read the subject ('title' metadata) and text from the following files:

.PDF .DOC .XLS .PPT .CSV 。文本 .DOCX .XLS .PPTX + OpenOffice的开放文档标准。

.PDF .DOC .XLS .PPT .CSV .TXT .DOCX .XLS .PPTX + the OpenOffice and Open Document standards.

开源将是真棒......但商业是OK了。

Open source would be awesome... but commercial is OK too.

我找不到任何东西任何地方！

I can't find anything anywhere!

推荐答案

我不认为你可以找到一个单一的IFilter，将能够访问所有这些类型的内容。通常情况下，的IFilter将是一种特定的技术。

I don't think you will be able to find a single IFilter that will be able to access the contents of all of those types. Typically, an IFilter will be for a specific technology.

例如，Adobe公司有一对PDF文件中，微软提供了一个用于办公，可以做的Word，Excel，PowerPoint中，CSV（我相信来自pre安装Windows）。

For example, Adobe have one for PDFs, Microsoft provide one for Office that can do Word, Excel, Powerpoint, CSV (that I believe comes pre-installed with Windows).
