Create Word 2007 document using OpenXML SDK with font size, font color and bold formatting

 

Step 1
Install OpenXML SDK 2.0. You can download from here:

Step 2
Add these assemblies:

• OpenXML SDK (browse to the folder where you installed OpenXML SDK)
• Windows Base

<assemblies><add assembly="DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="WindowsBase, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></assemblies>

Step 3
Import these :
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using System.Xml;
using System.IO;
using System.Text;
using DocumentFormat.OpenXml.Spreadsheet;
using DocumentFormat.OpenXml.Wordprocessing;
using System.Collections;

Step 4
Create a class that looks like this:

public class MyParagraph
{
    private string paragraphType;
    private string text;

    public MyParagraph()
    {
    }

    public MyParagraph(string pt, string t)
	{
        this.paragraphType = pt;
        this.text = t;
	}

    public string ParagraphType
    {
        get { return paragraphType; }
        set { paragraphType = value; }
    }

    public string Text
    {
        get { return text; }
        set { text = value; }
    }
}

Step 5

Create this method

private void GenerateDocument(string filename, ArrayList myparagraphs)
    {

        WordprocessingDocument doc =
        WordprocessingDocument.Create(filename,
        WordprocessingDocumentType.Document);
        MainDocumentPart mainPart = doc.AddMainDocumentPart();
        mainPart.Document = new Document();
        Body body = new Body();
        
        /* Create the contents */
        for (int i = 0; i < myparagraphs.Count; i++)
        {
            DocumentFormat.OpenXml.Wordprocessing.Run run = new DocumentFormat.OpenXml.Wordprocessing.Run();        
            MyParagraph p = (MyParagraph)myparagraphs[i];
            string txt = p.Text;
            if (p.ParagraphType.Equals("Header1"))
            {                
                DocumentFormat.OpenXml.Wordprocessing.RunProperties runProperties = new DocumentFormat.OpenXml.Wordprocessing.RunProperties();
                runProperties.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Bold());
                DocumentFormat.OpenXml.Wordprocessing.FontSize fs = new DocumentFormat.OpenXml.Wordprocessing.FontSize();
                fs.Val = "50";
                DocumentFormat.OpenXml.Wordprocessing.Color c = new DocumentFormat.OpenXml.Wordprocessing.Color();
                c.Val = "red";
                runProperties.AppendChild(fs);
                runProperties.AppendChild(c);
                run.AppendChild(runProperties);
                run.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Text(txt));     
            }
            else
            {
                run.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Text(txt));
            }
            Paragraph para = new Paragraph(run);
            body.AppendChild(para);
        }

        mainPart.Document.Append(body);
                
        /* Save the results and close */
        mainPart.Document.Save();
        doc.Close();
}

Step 6

Call the function defined in Step 5 from an ASP.NET document

private void Generate(){

private void Generate()
{
  MyParagraph p1 = new MyParagraph("Header1", "Line 1");
  MyParagraph p2 = new MyParagraph("Header2", "Line 2");
  MyParagraph p3 = new MyParagraph("Header3", "Line 3");
  MyParagraph p4 = new MyParagraph("Header4", "Line 4");
  ArrayList list = new ArrayList();
  list.Add(p1); list.Add(p2); list.Add(p3); list.Add(p4);
  GenerateDocument(Server.MapPath("Output\\Document.docx"),list);
}
