Code Examples

Create Word and Docx Document

Create the Word document by instantiating the WordDocument class using one of its constructors. After that, use the SaveAs method to export the Word document.

using IronWord;
using IronWord.Models;

// Create textrun
TextRun textRun = new TextRun("Sample text");

Paragraph paragraph = new Paragraph();

// Create a new Word document
WordDocument doc = new WordDocument(paragraph);

// Export docx
Imports IronWord
Imports IronWord.Models

' Create textrun
Private textRun As New TextRun("Sample text")

Private paragraph As New Paragraph()

' Create a new Word document
Dim doc As New WordDocument(paragraph)

' Export docx
VB   C#

Add Image

An image cannot be added by itself; instead, it should be added to one of the document structures, such as a Paragraph, TableCell, or Section. Use the AddImage method to add an image.

using IronWord;
using IronWord.Models;

// Load docx
WordDocument doc = new WordDocument("document.docx");

// Configure image
IronWord.Models.Image image = new IronWord.Models.Image("image.jpg");
image.Width = 250; // In unit pixel
image.Height = 200; // In unit pixel
Paragraph paragraph = new Paragraph();

// Add image

// Add paragraph

// Export docx
Imports IronWord
Imports IronWord.Models

' Load docx
Private doc As New WordDocument("document.docx")

' Configure image
Private image As New IronWord.Models.Image("image.jpg")
image.Width = 250 ' In unit pixel
image.Height = 200 ' In unit pixel
Dim paragraph As New Paragraph()

' Add image

' Add paragraph

' Export docx
VB   C#

Add Table

Adding a table requires a little more work, as the table, rows, columns, and table cells have to be created. However, with this setup, there are significant configuration opportunities. Each cell can have a different style. Explore the various border styles, offering a vast selection of 24 types.

using IronWord;
using IronWord.Models;

// Create table cell
TableCell cell = new TableCell();

TextRun textRun = new TextRun();
textRun.Text = "Sample text";

// Add textrun to the cell
cell.AddContent(new Paragraph(textRun));

// Configure border style
BorderStyle borderStyle = new BorderStyle();
borderStyle.BorderColor = new IronColor(IronSoftware.Drawing.Color.Black);
borderStyle.BorderValue = IronWord.Models.Enums.BorderValues.Thick;
borderStyle.BorderSize = 5;

// Configure table border
TableBorders tableBorders = new TableBorders() {
    TopBorder = borderStyle,
    RightBorder = borderStyle,
    BottomBorder = borderStyle,
    LeftBorder = borderStyle,

cell.Borders = tableBorders;

// Create row and add cell
TableRow row = new TableRow();

// Create table and add row
Table table = new Table();

// Create new Word document from the table
WordDocument doc = new WordDocument(table);

// Export Word document
Imports IronWord
Imports IronWord.Models

' Create table cell
Private cell As New TableCell()

Private textRun As New TextRun()
textRun.Text = "Sample text"

' Add textrun to the cell
cell.AddContent(New Paragraph(textRun))

' Configure border style
Dim borderStyle As New BorderStyle()
borderStyle.BorderColor = New IronColor(IronSoftware.Drawing.Color.Black)
borderStyle.BorderValue = IronWord.Models.Enums.BorderValues.Thick
borderStyle.BorderSize = 5

' Configure table border
Dim tableBorders As New TableBorders() With {
	.TopBorder = borderStyle,
	.RightBorder = borderStyle,
	.BottomBorder = borderStyle,
	.LeftBorder = borderStyle

cell.Borders = tableBorders

' Create row and add cell
Dim row As New TableRow()

' Create table and add row
Dim table As New Table()

' Create new Word document from the table
Dim doc As New WordDocument(table)

' Export Word document
VB   C#
