I am creating a sample document using the code below.

C#

public static void CreateDocumentFile(string file)
       {
           // Create a Wordprocessing document.
           using (WordprocessingDocument package = WordprocessingDocument.Create(file, WordprocessingDocumentType.Document))
           {
               // Add a new main document part.
               package.AddMainDocumentPart();

               // Create the Document DOM.
               package.MainDocumentPart.Document =
                 new Document(
                   new Body(
                     new Paragraph(
                       new Run(
                         new Text("Hello World!")))));

               // Save changes to the main document part.
               package.MainDocumentPart.Document.Save();
           }

Document is created at the desired location but when i open it, gives me an error ,

The file cannot be opened because there are some problem in the content and it is pointing that my document.xml file contains error on line:1 col:198

my document.xml contains

<pre lang="xml"><?xml version="1.0" encoding="utf-8"?><w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><w:body><a:p xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"><a:r><a:t>Hello World!</a:t></a:r></a:p></w:body></w:document>

Can you open this document with Word. Are you using compatible version of Microsoft.Office.Interop?

Solution 1

By testing your code with Open XML Format SDK 2.0[^] (v 2.0.5022.0) [NET 3.5]
or Open XML SDK 2.5[^] (v 2.5.5631.0) [NET 4.0] my output looked like this (output formatted):

XML

<?xml version="1.0" encoding="utf-8"?>
<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
 <w:body>
  <w:p>
   <w:r>
    <w:t>Hello World!</w:t>
   </w:r>
  </w:p>
 </w:body>
</w:document>

and I was able to open the Document in Word 2007 and WordPad 6.

I got the same as you, there's nothing wrong with the code itself, the problem is a bad using. See my answer.

Yes, the wordprocessingml vs. drawingml.
Good point, Valery!

Hello,

That's a wrong using statement...

The Paragraph class exists in 3 different namespaces, and I think you chose the wrong one.

When dealing with a Word document you should use DocumentFormat.OpenXml.Wordprocessing.Paragraph

I think you used DocumentFormat.OpenXml.Drawing.Paragraph as the schema shown in your example is the schema for the drawing namespace.

So the solution is simple in your using section, remove:

C#

using DocumentFormat.OpenXml.Drawing;

and replace by the correct one:

C#

using DocumentFormat.OpenXml.Wordprocessing;

Valery.
