C#でDOCXファイルを作成する方法

How to Create DOCX File in C#

1. Install the NuGet package IronWord.
2. Take the required namespaces and import them from IronWord.
3. To generate document files, add a new TextRun.
4. Make a new Body and Document.
5. Fill the Body with content (paragraphs, tables, etc.).
6. Using WordDocument, create a new WordDocument.
7. Assigning the Document object to the TextRun, Paragraph Document property will save the modifications.

Getting to Know the DOCX Format

Before delving into the coding, let us clarify what a DOCX file is. Microsoft Word and other Word processing programs save documents in the DOCX file format. It is based on the ZIP-compressed XML-based [Office Open XML (OOXML) standard](https://en.wikipedia.org/wiki/Office_Open_XML#:~:text=Office%20Open%20XML%20(also%20informally,initial%20version%20as%20ECMA%2D376.). This allows utilizing APIs from Microsoft and other developers to manipulate it programmatically relatively simply.

IronWord

Iron Software created the Word document library known as IronWord. When it comes to offering strong capabilities for Word document manipulation in .NET applications, IronWord shines. To help .NET C# developers include the ability to create, read, and modify Word and DOCX documents in their programs, IronWord is a robust Word document library.

Creating a New Project in Visual Studio

To launch the Visual Studio application, use the File menu and choose File. Click "New Project," then choose "Console application."

Enter the project name in the designated text field after choosing the file location. Next, as seen in the sample below, click the Create button and choose the required .NET Framework.

The Visual Studio project's organization will then depend on the selected application. To add code and construct the application, just open the program.cs file. The internet application, Windows, or console can all be used.

After that, the library may be added and the code tested.

Install-Package IronWord

Create DOCX Using IronWord

Instantiate a WordDocument object to start a new Word document. To initialize the document, you can use any object that makes up the document structure, like a paragraph, table, or section. Here's an easy illustration in the following code snippet:

using IronWord;
using IronWord.Models;

namespace ConsoleApp1
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Create a text run, which is a portion of the document's text content.
            TextRun textRun = new TextRun("Hello, IronWord!");

            // Create a paragraph and add the text run to it.
            Paragraph paragraph = new Paragraph();
            paragraph.AddTextRun(textRun);

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

            // Export and save the DOCX file to the specified path.
            doc.SaveAs("document.docx");
        }
    }
}

using IronWord;
using IronWord.Models;

namespace ConsoleApp1
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Create a text run, which is a portion of the document's text content.
            TextRun textRun = new TextRun("Hello, IronWord!");

            // Create a paragraph and add the text run to it.
            Paragraph paragraph = new Paragraph();
            paragraph.AddTextRun(textRun);

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

            // Export and save the DOCX file to the specified path.
            doc.SaveAs("document.docx");
        }
    }
}

Imports IronWord
Imports IronWord.Models

Namespace ConsoleApp1
	Friend Class Program
		Shared Sub Main(ByVal args() As String)
			' Create a text run, which is a portion of the document's text content.
			Dim textRun As New TextRun("Hello, IronWord!")

			' Create a paragraph and add the text run to it.
			Dim paragraph As New Paragraph()
			paragraph.AddTextRun(textRun)

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

			' Export and save the DOCX file to the specified path.
			doc.SaveAs("document.docx")
		End Sub
	End Class
End Namespace

We can add text to the document with the help of the TextRun class, which allows us to pass the text into the paragraph object with the help of the AddTextRun method. Then we are creating a new WordDocument object to create a new DOCX file. Then, by using the SaveAs method, we can save the new DOCX document in the desired location. Below is the output generated from the above code.

Conclusion

We've looked at how to use C# to generate a DOCX document file in this guide. The fundamentals of the DOCX format have been discussed, along with the Open XML SDK and the DocX library, and examples of how to use them to generate, edit, and save DOCX files have been given.

All of these tools and methods will put you in a strong position to handle a variety of document creation tasks in your C# projects. Learning document production in C# is a useful ability that will help you in various situations, whether you're automating report generation, developing document management systems, or just making templates for end users.

For developers working with .NET C#, IronWord is a powerful and adaptable Word document library. It enables developers to read, write, and edit Word (DOCX) documents in their apps with ease. IronWord's user-friendly API makes processing Word documents easier. Without requiring Microsoft Word to be installed or depending on Office Interop, developers may create and edit Word files directly within their .NET projects. Adding text, paragraphs, and other elements to new Word documents is made simple.

IronWord is $799 when it first comes out. In addition, customers who pay a one-year membership fee can receive assistance and updates on products. For a fee, IronWord offers a defense against unrestrained redistribution. To find out more about the approximate cost, go to this page. View more about Iron Software by clicking this link.
