Question

I am trying to get text from .docx file and when use this code in visual studio it's working well but when uploading to server I get the error:

Error: Could not load file or assembly 'DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true)) {
    DocumentFormat.OpenXml.Wordprocessing.Body body
        = wordDoc.MainDocumentPart.Document.Body;
    totaltext = body.InnerText;
}

Answer 1

You must register the dll "DocumentFormat.OpenXml.dll" on each machine you want to use your code.

Register the dll on the server and it should works just fine
