IronWord: The C# DOCX Library

IronWord is a flexible and scalable library with a straightforward and easy-to-use API that eliminates the hassle of integrating Word documents into applications. Whether you want to add and integrate a simple text word document to your application or create complex tables and reports to display to users, IronWord has everything covered.

Here are its most notable features:

1. Document Manipulation: IronWord allows developers to manipulate Word documents with ease. Whether users want to insert paragraphs of text or more complex structures such as tables and images, IronWord can do it all.

2. Cross-Platform Support and Compatibility: IronWord is designed to be flexible and supports developers on multiple platforms. It supports various .NET Core (8, 7, 6, 5, and 3.1+), .NET Standard (2.0+), .NET Framework (4.6.2+), and even Azure. Furthermore, developers can utilize IronWord on different platforms and systems, including but not limited to Windows, Linux, macOS, and Android. It covers the most common platforms and allows developers to build cross-platform applications quickly.

3. Independence from Microsoft Office: One common trouble when integrating Word documents in .NET applications is that popular libraries such as Interop require a licensed installation of Microsoft Office. However, IronWord alleviates that problem by being independent of that restriction. Developers can fully leverage the power of Word documents without being restricted by the license and installation of Microsoft Word.

4. Formatting Options: IronWord offers extensive support for formatting and styling, allowing developers to make the document unique. Developers can apply fonts to their text, colors, alignments, and other complex formatting, such as table styles.

5. Ease of Use and Extensive Support: Along with an easy-to-understand API and straightforward method calls, IronWord also provides extension API references and code examples to help developers determine the most optimal way to utilize IronWord.

Creating a New Console Project in Visual Studio

Before we dive into the example, let's start by creating a blank console project in Visual Studio.

We then provide a name and a save location for the project.

Next, select the .NET framework that you will be using. In this example, I will be using .NET 8.0.

After creating and setting up the new console project, let's install our C# word library, IronWord.

Installing IronWord

There are two ways to install IronWord.

Install-Package IronWord

// Replace the license key variable with the trial key you obtained
IronWord.License.LicenseKey = "REPLACE-WITH-YOUR-KEY";

// Replace the license key variable with the trial key you obtained
IronWord.License.LicenseKey = "REPLACE-WITH-YOUR-KEY";

' Replace the license key variable with the trial key you obtained
IronWord.License.LicenseKey = "REPLACE-WITH-YOUR-KEY"

Reading Word Documents in C#

After installing the prerequisites, we will demonstrate the simplicity of reading a Microsoft Word document using IronWord in the following code.

First, we import the necessary namespaces. Using IronWord, we create a new document and add sample text. We then access the paragraphs and text using the WordDocument object to print out the text within the Word document.

using IronWord;
using IronWord.Models;

#region Licensing
// Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE";
#endregion

// Create text run with sample text
Text textRunExample = new Text("Sample text");

// Create a paragraph and add the text run to it
Paragraph paragraphExample = new Paragraph();
paragraphExample.AddChild(textRunExample);

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

// Export the document as a DOCX file
doc.SaveAs("document.docx");

// Access paragraphs and text runs within the document
foreach (Paragraph paragraph in doc.Paragraphs)
{
    foreach (Text textRun in paragraph.Texts)
    {
        // Access text content
        string content = textRun.Text;
        // Display the content to the console
        Console.WriteLine(content);
    }
}

using IronWord;
using IronWord.Models;

#region Licensing
// Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE";
#endregion

// Create text run with sample text
Text textRunExample = new Text("Sample text");

// Create a paragraph and add the text run to it
Paragraph paragraphExample = new Paragraph();
paragraphExample.AddChild(textRunExample);

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

// Export the document as a DOCX file
doc.SaveAs("document.docx");

// Access paragraphs and text runs within the document
foreach (Paragraph paragraph in doc.Paragraphs)
{
    foreach (Text textRun in paragraph.Texts)
    {
        // Access text content
        string content = textRun.Text;
        // Display the content to the console
        Console.WriteLine(content);
    }
}

Imports IronWord
Imports IronWord.Models

#Region "Licensing"
' Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE"
'#End Region

' Create text run with sample text
Dim textRunExample As New Text("Sample text")

' Create a paragraph and add the text run to it
Dim paragraphExample As New Paragraph()
paragraphExample.AddChild(textRunExample)

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

' Export the document as a DOCX file
doc.SaveAs("document.docx")

' Access paragraphs and text runs within the document
For Each paragraph As Paragraph In doc.Paragraphs
	For Each textRun As Text In paragraph.Texts
		' Access text content
		Dim content As String = textRun.Text
		' Display the content to the console
		Console.WriteLine(content)
	Next textRun
Next paragraph

Let's explore the methods and parameters to read word files from the above code.

1. We first create a Text object and assign the string "Sample text" to it.

2. We then instantiate a Paragraph object and add the "textRunExample" to it.

3. We also instantiate a WordDocument object, name it WordDocument doc, and pass the paragraphExample to it to create a new Word document containing the paragraph.

4. The code saves the Word document with the file name "document.docx" for later use.

5. To access the paragraphs in the Word document we just created, we access the "Paragraphs" property of the WordDocument object. The "Paragraphs" property is a list. Hence, we call a foreach loop to iterate through it.

6. To obtain the text within the paragraph, we access the "Texts" property of Paragraphs. This also returns a list of Text.

7. Finally, we assign the Text to a string variable named "content" and print it out to the console.

using IronWord;
using IronWord.Models;

#region Licensing
// Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE";
#endregion

// Load an existing Word document
WordDocument doc = new WordDocument("existing_document.docx");

// Access paragraphs and text runs within the document
foreach (Paragraph paragraph in doc.Paragraphs)
{
    foreach (Text textRun in paragraph.Texts)
    {
        // Access text content
        string content = textRun.Text;
        // Display the content to the console
        Console.WriteLine(content);
    }
}

using IronWord;
using IronWord.Models;

#region Licensing
// Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE";
#endregion

// Load an existing Word document
WordDocument doc = new WordDocument("existing_document.docx");

// Access paragraphs and text runs within the document
foreach (Paragraph paragraph in doc.Paragraphs)
{
    foreach (Text textRun in paragraph.Texts)
    {
        // Access text content
        string content = textRun.Text;
        // Display the content to the console
        Console.WriteLine(content);
    }
}

Imports IronWord
Imports IronWord.Models

#Region "Licensing"
' Set the IronWord license key before using the IronWord functionalities
IronWord.License.LicenseKey = "YOUR-KEY-HERE"
'#End Region

' Load an existing Word document
Dim doc As New WordDocument("existing_document.docx")

' Access paragraphs and text runs within the document
For Each paragraph As Paragraph In doc.Paragraphs
	For Each textRun As Text In paragraph.Texts
		' Access text content
		Dim content As String = textRun.Text
		' Display the content to the console
		Console.WriteLine(content)
	Next textRun
Next paragraph

Conclusion
