推荐答案

您可以使用Windows内置的IFilter接口从任何受支持的文件类型提取文本和属性(作者，标题等).这是一个COM接口，因此您将使用.NET互操作工具.

You can use the IFilter interface built into Windows to extract text and properties (author, title, etc.) from any supported file type. It's a COM interface so you would have use the .NET interop facilities.

您还必须从Adobe下载免费的PDF IFilter驱动程序.
