C# programmatic method of reading document Doc, Docx and Pdf content

This article describes the C# programmatic method of reading documents Doc, Docx and Pdf content. Share it for your reference. The specific analysis is as follows:

Doc Document: Microsoft Word 14.0 Object Library (GAC object, you need to install word before calling. Different versions of word installed, the version number of COM will also be different)
Docx Documentation: Microsoft Word 14.0 Object Library (GAC object, you need to install word before calling. Different versions of word installed, and the version number of COM will also be different)
PDF Document: PDFBox
