Watermark on word document body

[SamiRND]

I am using open XML 3.2 version to add watermark on word file. I am using the below code.

 using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(filePath, true))
 {


     // Get the body of the document
     var body = wordDocument.MainDocumentPart.Document.Body;

     // Check if the document body is null or corrupted, and rebuild it if necessary
     if (body == null)
     {
         body = new Body(); // Create a new body if needed
         wordDocument.MainDocumentPart.Document.Append(body);
     }

   
     body.AppendChild(new DocumentFormat.OpenXml.Drawing.Paragraph(new DocumentFormat.OpenXml.Drawing.Run(new DocumentFormat.OpenXml.Drawing.Text("This is some inline text"))));

     // Ensure all parts are saved correctly
     wordDocument.MainDocumentPart.Document.Save();
}

There is no error. but the word file gets corrupted and is not opening.

error message i am getting when open the file.

Hi @SamiRND,

You're using the wrong namespace for Paragraph, Run, and Text. You need to use the DocumentFormat.OpenXml.Wordprocessing namespace.

new DocumentFormat.OpenXml.Wordprocessing.Paragraph(new DocumentFormat.OpenXml.Wordprocessing.Run(new DocumentFormat.OpenXml.Wordprocessing.Text("Hello World")))
