What is IronWord?

IronWord is a C# NuGet library from Iron Software developed to facilitate the creation, manipulation, and management of Microsoft Word files programmatically. It allows developers to automate the process of generating Word documents with aligned text, making it easier to dynamically generate reports, invoices, letters, and other types of documents within their applications.

Prerequisites

A quick reminder to make sure you have the following before we get started:

• Visual Studio is installed on your machine.
• The latest .NET Framework is installed.

Step 1: Create a New Project in Microsoft Visual Studio

Now, let us begin by creating a new Visual Studio project.

Select the Console application template on the screen below.

Provide the project name and location.

Select the .NET Version, preferably the latest one with support, and click Create.

Step 2: Install IronWord Using NuGet Package Manager

Install the IronWord NuGet package from the NuGet package manager as below in Visual Studio.

Alternatively, please install it using CLI directly using the command below.

dotnet add package IronWord --version 2024.9.1

Step 3: Generate a Word Document with Text Alignment

The below code example shows how to generate a Word document with center-aligned text.

using IronWord;
using IronWord.Models;

class Program
{
    static void Main()
    {
        // Set your license key for IronWord
        License.LicenseKey = "your key";

        // Create a new document
        var document = new WordDocument();

        // Create a paragraph and add text
        Paragraph paragraph = new Paragraph();
        Text text = new Text() { Text = "IronWord, From IronSoftware" };
        paragraph.AddText(text); // Add text to the paragraph

        // Set text alignment to center aligned
        paragraph.Alignment = IronWord.Models.Enums.TextAlignment.Center;

        // Add the first paragraph to the document
        document.AddParagraph(paragraph);

        // Save the document with the specified filename
        document.SaveAs("output.docx");
    }
}

using IronWord;
using IronWord.Models;

class Program
{
    static void Main()
    {
        // Set your license key for IronWord
        License.LicenseKey = "your key";

        // Create a new document
        var document = new WordDocument();

        // Create a paragraph and add text
        Paragraph paragraph = new Paragraph();
        Text text = new Text() { Text = "IronWord, From IronSoftware" };
        paragraph.AddText(text); // Add text to the paragraph

        // Set text alignment to center aligned
        paragraph.Alignment = IronWord.Models.Enums.TextAlignment.Center;

        // Add the first paragraph to the document
        document.AddParagraph(paragraph);

        // Save the document with the specified filename
        document.SaveAs("output.docx");
    }
}

Imports IronWord
Imports IronWord.Models

Friend Class Program
	Shared Sub Main()
		' Set your license key for IronWord
		License.LicenseKey = "your key"

		' Create a new document
		Dim document = New WordDocument()

		' Create a paragraph and add text
		Dim paragraph As New Paragraph()
		Dim text As New Text() With {.Text = "IronWord, From IronSoftware"}
		paragraph.AddText(text) ' Add text to the paragraph

		' Set text alignment to center aligned

Step 4: Explore Text Alignment Property in IronWord

Now let us try different options.

using IronWord;
using IronWord.Models;
using IronWord.Models.Enums;

class Program
{
    static void Main()
    {
        // Set your license key for IronWord
        License.LicenseKey = "your key";

        // Create a new DOCX document
        var doc = new WordDocument();

        // Sample text for alignment
        Text text = new Text() { Text = "IronWord, From IronSoftware" };

        // Add paragraphs with different alignments
        AddPara(doc, text, TextAlignment.Center);
        AddPara(doc, text, TextAlignment.Left);
        AddPara(doc, text, TextAlignment.Right);
        AddPara(doc, text, TextAlignment.Justified);

        // Save the document with all alignment options
        doc.SaveAs("outputAllOptions.docx");
    }

    // Method to add a paragraph to the document with specified alignment
    private static void AddPara(WordDocument doc, Text text, TextAlignment alignment)
    {
        Paragraph paragraph = new Paragraph();
        paragraph.AddText(text);
        paragraph.Alignment = alignment;
        doc.AddParagraph(paragraph);
    }
}

using IronWord;

        doc.SaveAs("outputAllOptions.docx");
    }

    // Method to add a paragraph to the document with specified alignment
    private static void AddPara(WordDocument doc, Text text, TextAlignment alignment)
    {
        Paragraph paragraph = new Paragraph();
        paragraph.AddText(text);
        paragraph.Alignment = alignment;
        doc.AddParagraph(paragraph);
    }
}
