Read From Text by Word in C

With GemBox.Certificate you tin open up and read many Word file formats (like DOCX, Medico, RTF, and HTML) in the same manner. The documents can be loaded using 1 of the DocumentModel.Load methods from your C# and VB.NET application. These methods enable y'all to piece of work with a physical file (when providing the file's path) or with an in-memory file (when providing the file'south Stream).

You tin specify the format of your Discussion file by providing an object from the LoadOptions derived class (like DocxLoadOptions, DocLoadOptions, RtfLoadOptions, and HtmlLoadOptions). Or you tin permit GemBox.Document choose the appropriate options for you when opening the file by omitting the LoadOptions.

The following case shows the easiest way how you tin read the document's text from a Discussion file.

Reading Word document's elements

Likewise reading the text of the whole document, you can also read just some part of it, like a specific Department element or HeaderFooter element. Each element has a Content property with which you can extract its text via the Content.ToString method.

The following example shows how yous can open a document and traverse through all Paragraph elements and their kid Run elements, and read their text and formatting. To read more about the visual data of the content elements, see the Formattings and Styles aid page.

By combining these two examples you tin achieve various tasks, like selecting only the Table elements and reading their text content, or selecting only the Picture show elements and extracting their images, or reading the Run.Text property of only the highlighted elements (the ones that take CharacterFormat.HighlightColor).

Reading Word certificate's pages

Word files (DOCX, DOC, RTF, HTML, etc.) don't take a page concept, which means they don't comprise information about how many pages they occupy nor which element is on which page.

They are of a flow document type and their content is written in a flow-able fashion. The page concept is specific to the Discussion application(south) that renders or displays the document.

On the other hand, files of stock-still certificate blazon (PDF, XPS, etc.) practice have a folio concept. Their content is fixed: it'south defined on which verbal folio location the elements are rendered.

GemBox.Document uses its rendering engine to paginate and render the document's content when saving to PDF, XPS, or paradigm format. So, the best and the easiest way to read the text content of some specific page is to convert a Word document to a PDF file (or save a specific Word page every bit a PDF) with GemBox.Document and so read the PDF folio'south text content with our other component, GemBox.Pdf.

Nevertheless, the following example shows how you can utilize GemBox.Document's rendering engine to retrieve each document page as a FrameworkElement object from a WPF framework and and so extract text from information technology using the provided FrameworkElement.ToText extension method.
