Office Interopを使用せずにC#でワード文書を作成する方法

How to Create Word Documents Without Office Interop in C#

1. Create a new C# project.
2. Install the IronWord library.
3. Create a Word document using the IronWord library.
4. Add content to the now existing document.
5. Save the created Word document.
6. Open and display the created Word document.

Prerequisites:

1. Visual Studio: Ensure you have Visual Studio or any other C# development environment installed.
2. NuGet Package Manager: Make sure you can use NuGet to manage packages in your project.

Step 1: Create a New C# Project

Create a new C# console application or use an existing project where you want to generate the Word document.

Select the console application template and click next.

In the next step, you can provide the solution and project names.

Select the .NET Version and click "Create".

Step 2: Install the IronWord Library

Open your C# project and install the IronWord library using the NuGet Package Manager Console:

Install-Package IronWord -Version 2024.1.2

The NuGet package can also be installed using Visual Studio Package Manager, as shown below.

Step 3: Create and Save a Word Document using the IronWord Library

Let's start with the simple example of creating a Word document using the IronWord library. The following code demonstrates how to create an essential Word document with a single paragraph containing the text "Hello, World!"

using IronWord;
using IronWord.Models;

// Create a text run instance with "Hello, World!" content
TextRun textRun = new TextRun("Hello, World!");

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

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

// Save the document as a .docx file
doc.SaveAs("example.docx"); // Saves the file to disk with the name example.docx

using IronWord;
using IronWord.Models;

// Create a text run instance with "Hello, World!" content
TextRun textRun = new TextRun("Hello, World!");

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

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

// Save the document as a .docx file
doc.SaveAs("example.docx"); // Saves the file to disk with the name example.docx

Imports IronWord
Imports IronWord.Models

' Create a text run instance with "Hello, World!" content
Private textRun As New TextRun("Hello, World!")

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

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

' Save the document as a .docx file
doc.SaveAs("example.docx") ' Saves the file to disk with the name example.docx

After executing the above code example, the new document file, example.docx, is created and the output is as shown below.

This is a fundamental example of generating a Word document file using IronWord. For more information, you can read the Documentation.

Adding Paragraphs with Style to a Word Document

Now that we know how to create a simple Word document using IronWord, let's add paragraphs and styled text.

TextRun can also take style data, enhancing the text's visual representation. Text can be set with styles such as strikethrough, bold, italic, and underline.

Modify and add the code below to the program you have made previously.

using IronWord;
using IronWord.Models;

// Create text runs with different styles
TextRun textRun = new TextRun("Hello, World!"); // Simple string
Paragraph paragraph = new Paragraph();
paragraph.AddTextRun(textRun);

// Configure and add italic text
TextRun introText = new TextRun("This is an example paragraph with italic and bold styling.");
TextStyle italicStyle = new TextStyle()
{
    IsItalic = true
};
TextRun italicText = new TextRun("Italic example sentence.", italicStyle);

// Configure and add bold text
TextStyle boldStyle = new TextStyle()
{
    IsBold = true
};
TextRun boldText = new TextRun("Bold example sentence.", boldStyle);

// Add text runs to the paragraph
paragraph.AddTextRun(introText);
paragraph.AddTextRun(italicText);
paragraph.AddTextRun(boldText);

// Create and save the new Word document
WordDocument doc = new WordDocument(paragraph);
doc.SaveAs("example.docx"); // Saves the file to disk with the name example.docx

using IronWord;
using IronWord.Models;

// Create text runs with different styles
TextRun textRun = new TextRun("Hello, World!"); // Simple string
Paragraph paragraph = new Paragraph();
paragraph.AddTextRun(textRun);

// Configure and add italic text
TextRun introText = new TextRun("This is an example paragraph with italic and bold styling.");
TextStyle italicStyle = new TextStyle()
{
    IsItalic = true
};
TextRun italicText = new TextRun("Italic example sentence.", italicStyle);

// Configure and add bold text
TextStyle boldStyle = new TextStyle()
{
    IsBold = true
};
TextRun boldText = new TextRun("Bold example sentence.", boldStyle);

// Add text runs to the paragraph
paragraph.AddTextRun(introText);
paragraph.AddTextRun(italicText);
paragraph.AddTextRun(boldText);

// Create and save the new Word document
WordDocument doc = new WordDocument(paragraph);
doc.SaveAs("example.docx"); // Saves the file to disk with the name example.docx

Imports IronWord
Imports IronWord.Models

' Create text runs with different styles
Private textRun As New TextRun("Hello, World!") ' Simple string
Private paragraph As New Paragraph()
paragraph.AddTextRun(textRun)

' Configure and add italic text
Dim introText As New TextRun("This is an example paragraph with italic and bold styling.")
Dim italicStyle As New TextStyle() With {.IsItalic = True}
Dim italicText As New TextRun("Italic example sentence.", italicStyle)

' Configure and add bold text
Dim boldStyle As New TextStyle() With {.IsBold = True}
Dim boldText As New TextRun("Bold example sentence.", boldStyle)

' Add text runs to the paragraph
paragraph.AddTextRun(introText)
paragraph.AddTextRun(italicText)
paragraph.AddTextRun(boldText)

' Create and save the new Word document
Dim doc As New WordDocument(paragraph)
doc.SaveAs("example.docx") ' Saves the file to disk with the name example.docx

Adding a Table to a Word Document

For clear representation of data, it can also be represented in a grid. When data is arranged as a grid, it is called a table. Using IronWord, we can add tables and images to the Word document as shown below:

using IronWord;
using IronWord.Models;

// Create a table cell with sample text
TableCell cell = new TableCell();
TextRun textRun = new TextRun("Sample text");

// Add text run to the cell as a paragraph
cell.AddContent(new Paragraph(textRun));

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

// Set table borders
TableBorders tableBorders = new TableBorders
{
    TopBorder = borderStyle,
    RightBorder = borderStyle,
    BottomBorder = borderStyle,
    LeftBorder = borderStyle
};
cell.Borders = tableBorders;

// Create a table row and add cells to it
TableRow row = new TableRow();
row.AddCell(cell); // Add the first cell
row.AddCell(cell); // Add the second cell, duplicating to mimic a row with two identical cells

// Create a table and add the row to the table
Table table = new Table();
table.AddRow(row);

// Create and save a Word document using the table
WordDocument doc = new WordDocument(table);
doc.SaveAs("Document.docx"); // Saves the file to disk with the name Document.docx

using IronWord;
using IronWord.Models;

// Create a table cell with sample text
TableCell cell = new TableCell();
TextRun textRun = new TextRun("Sample text");

// Add text run to the cell as a paragraph
cell.AddContent(new Paragraph(textRun));

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

// Set table borders
TableBorders tableBorders = new TableBorders
{
    TopBorder = borderStyle,
    RightBorder = borderStyle,
    BottomBorder = borderStyle,
    LeftBorder = borderStyle
};
cell.Borders = tableBorders;

// Create a table row and add cells to it
TableRow row = new TableRow();
row.AddCell(cell); // Add the first cell
row.AddCell(cell); // Add the second cell, duplicating to mimic a row with two identical cells

// Create a table and add the row to the table
Table table = new Table();
table.AddRow(row);

// Create and save a Word document using the table
WordDocument doc = new WordDocument(table);
doc.SaveAs("Document.docx"); // Saves the file to disk with the name Document.docx

Imports IronWord
Imports IronWord.Models

' Create a table cell with sample text
Private cell As New TableCell()
Private textRun As New TextRun("Sample text")

' Add text run to the cell as a paragraph
cell.AddContent(New Paragraph(textRun))

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

' Set table borders
Dim tableBorders As New TableBorders With {
	.TopBorder = borderStyle,
	.RightBorder = borderStyle,
	.BottomBorder = borderStyle,
	.LeftBorder = borderStyle
}
cell.Borders = tableBorders

' Create a table row and add cells to it
Dim row As New TableRow()
row.AddCell(cell) ' Add the first cell
row.AddCell(cell) ' Add the second cell, duplicating to mimic a row with two identical cells

' Create a table and add the row to the table
Dim table As New Table()
table.AddRow(row)

' Create and save a Word document using the table
Dim doc As New WordDocument(table)
doc.SaveAs("Document.docx") ' Saves the file to disk with the name Document.docx

In the example above, we added a table to a Word document using borders.

Adding Images to a Word Document

Images enhance the document's presentation and can add more colors and visual appeal.

Images can be added programmatically to a Word document using IronWord as shown in the code below:

using IronWord;
using IronWord.Models;

// Load a new document
WordDocument doc = new WordDocument();

// Configure and add image to the document
IronWord.Models.Image image = new IronWord.Models.Image("SalesChart.jpg")
{
    Width = 200, // Set image width in pixels
    Height = 200 // Set image height in pixels
};
Paragraph paragraph = new Paragraph();
paragraph.AddImage(image); // Add image to paragraph
doc.AddParagraph(paragraph); // Add paragraph to the document

// Save the document as a .docx file
doc.SaveAs("save_document.docx"); // Saves the file to disk with the name save_document.docx

using IronWord;
using IronWord.Models;

// Load a new document
WordDocument doc = new WordDocument();

// Configure and add image to the document
IronWord.Models.Image image = new IronWord.Models.Image("SalesChart.jpg")
{
    Width = 200, // Set image width in pixels
    Height = 200 // Set image height in pixels
};
Paragraph paragraph = new Paragraph();
paragraph.AddImage(image); // Add image to paragraph
doc.AddParagraph(paragraph); // Add paragraph to the document

// Save the document as a .docx file
doc.SaveAs("save_document.docx"); // Saves the file to disk with the name save_document.docx

Imports IronWord
Imports IronWord.Models

' Load a new document
Private doc As New WordDocument()

' Configure and add image to the document
Private image As New IronWord.Models.Image("SalesChart.jpg") With {
	.Width = 200,
	.Height = 200
}
Private paragraph As New Paragraph()
paragraph.AddImage(image) ' Add image to paragraph
doc.AddParagraph(paragraph) ' Add paragraph to the document

' Save the document as a .docx file
doc.SaveAs("save_document.docx") ' Saves the file to disk with the name save_document.docx

Here, we are adding an image using IronWord.Models.Image with a Height and Width of 200 pixels to a paragraph.

{
    "IronWord.LicenseKey": "IRONWORD.MYLICENSE.KEY.TRIAL"
}
