I’m trying to take an existing document and if a header doesn’t exist, create one, and then add a watermark to the header that says “DRAFT” diagonally. I’ve followed an example posted here and I’ve gotten the code to the point where it will add the watermark if the header already exists.
The current issue is when I add a new header, add the reference to the document, and then add the watermark to the header, the document becomes corrupt and can no longer open in Word 2010.
To test I’ve been doing the following: Create a new word document from word itself with text of “TestDoc” in the main part of the page. Save to my desktop as “TestDoc.docx” and close the file. Then I run the app from Visual Studio. The code below will always make it corrupted. If I add a header to the file with no text in it and then hit save, the watermark will be displayed correctly.
Here is what I have so far:

UPDATE:
This is now resolved by changing the way the file is opened up. When we change the Main function to:
static void Main(string[] args)
{
//var doc = WordprocessingDocument.Open(@"C:\Users\loggedinuser\Desktop\TestDoc.docx", true);
//AddWatermark(doc);
//doc.MainDocumentPart.Document.Save();
byte[] sourceBytes = File.ReadAllBytes(@"C:\Users\loggedinuser\Desktop\TestDoc.docx");
MemoryStream inMemoryStream = new MemoryStream();
inMemoryStream.Write(sourceBytes, 0, (int)sourceBytes.Length);
var doc = WordprocessingDocument.Open(inMemoryStream, true);
AddWatermark(doc);
doc.MainDocumentPart.Document.Save();
doc.Close();
doc.Dispose();
doc = null;
using (FileStream fileStream = new FileStream(@"C:\Users\loggedinuser\Desktop\TestDoc.docx", System.IO.FileMode.Create))
{
inMemoryStream.WriteTo(fileStream);
}
inMemoryStream.Close();
inMemoryStream.Dispose();
inMemoryStream = null;
}
The document now correctly opens in word. Thanks Brad!

The document now correctly opens in word. Thanks to Brad B. a coworker at Sonoma Partners for finding this!
