add-in in VSTO - How to get text from Word document using Ribbon with button

问题

How can I do something with text in my word document using button in word add-in? I don't know, how to get text from document after click on the button, because Application is not accessible in Ribbon class.

回答1:

The following code should take the text found in the selection:

string textFromDoc;
textFromDoc = Globals.ThisAddIn.Application.Selection.Text;

You can also specify the Range by:

textFromDoc = Globals.ThisAddIn.Application.ActiveDocument.Range(0, 20).Text;

This will take the first 20 letters written in the active document. Bottom line, you can access Application by using:

Globals.ThisAddIn.Application
