Sample infrastructure.
String exedir = Path.getdirectoryname (assembly.getexecutingassembly (). Location) + Path.directoryseparatorchar;
String datadir = new Uri (new Uri (Exedir), @ ": /.. /data/"). LocalPath;

<summary>
Inserts a watermark into a document.
</summary>
<param name= "Doc" >the input document.</param>
<param name= "Watermarktext" >text of the Watermark.</param>
private static void Insertwatermarktext (Document doc, String watermarktext)
{
Create a watermark shape. This would be a WordArt shape.
You is free to try the other shape types as watermarks.
Shape watermark = new shape (doc, shapetype.textplaintext);

Set up the text of the watermark.
Watermark. Textpath.text = Watermarktext;
Watermark. textpath.fontfamily = "Arial";
Watermark. Width = 500;
Watermark. Height = 100;
Text'll is directed from the Bottom-left to the Top-right corner.
Watermark. Rotation =-40;
Remove the following and lines if you need a solid black text.
Watermark. Fill.color = Color.gray; Try Lightgray to get more word-style watermark
Watermark. Strokecolor = Color.gray; Try Lightgray to get more word-style watermark

Place the watermark in the page center.
Watermark. RelativeHorizontalPosition = Relativehorizontalposition.page;
Watermark. RelativeVerticalPosition = Relativeverticalposition.page;
Watermark. Wraptype = Wraptype.none;
Watermark. VerticalAlignment = Verticalalignment.center;
Watermark. HorizontalAlignment = HorizontalAlignment.Center;

Create a new paragraph and append the watermark to this paragraph.
Paragraph Watermarkpara = new Paragraph (DOC);
Watermarkpara.appendchild (watermark);

Insert the watermark into all headers for each document section.
foreach (section sect in Doc. Sections)
{
There could is up to three different headers in each section, since we want
The watermark to appear in all pages, insert into all headers.
Insertwatermarkintoheader (Watermarkpara, sect, Headerfootertype.headerprimary);
Insertwatermarkintoheader (Watermarkpara, sect, Headerfootertype.headerfirst);
Insertwatermarkintoheader (Watermarkpara, sect, Headerfootertype.headereven);
}
}

private static void Insertwatermarkintoheader (Paragraph Watermarkpara, section sect, Headerfootertype Headertype)
{
HeaderFooter Header = sect. Headersfooters[headertype];

if (header = = null)
{
There is no header of the specified type in the current section, create it.
Header = new HeaderFooter (sect. Document, Headertype);
Sect. Headersfooters.add (header);
}

Insert a clone of the watermark into the header.
Header. AppendChild (Watermarkpara.clone (true));
}
}
}
