Set the Font for a Paragraph in C#
Setting fonts is a fundamental task when working with Word documents in C#. Spire.Doc offers the ParagraphStyle class, which lets you specify font family, size, style, and text color. Once you've created a style, you can apply it to format a paragraph with the desired settings.
The detailed steps to set the font for a paragraph using C# are as follows:
- Create a Document object.
- Add a section and a paragraph to the document.
- Append text to the paragraph.
- Create a ParagraphStyle object.
- Get the CharacterFormat object through the ParagraphStyle.CharacterFormat property.
- Set the font style, name, size and text color using the properties under the CharacterFormat object.
- Add the style to the document using the Document.Styles.Add() method.
- Apply the defined style to the paragraph using the Paragraph.ApplyStyle() method.
- Save the document to a Word file.
Here is an example that demonstrates how to set the font for a paragraph when creating a new Word document in C#:
- C#
using Spire.Doc; using Spire.Doc.Documents; using System.Drawing; namespace SetFontForParagraph { class Program { static void Main(string[] args) { // Create a Document object Document doc = new Document(); // Add a section Section section = doc.AddSection(); // Set the page margins section.PageSetup.Margins.All = 40f; // Add a paragraph Paragraph paragraph = section.AddParagraph(); // Append text to the paragraph paragraph.AppendText("Spire.Doc for .NET is a powerful library designed for developers " + "working with document processing in the .NET environment. It enables users to create, " + "read, modify, and convert various types of document formats, such as DOC, DOCX, PDF, " + "and more, without the need for Microsoft Office installed on the machine."); // Create a ParagraphStyle object ParagraphStyle style = new ParagraphStyle(doc); // Set the style name style.Name = "myStyle"; // Set the font style, name, size and text color style.CharacterFormat.Bold = false; style.CharacterFormat.TextColor = Color.Black; style.CharacterFormat.FontName = "Times New Roman"; style.CharacterFormat.FontSize = 14; // Add the style the document doc.Styles.Add(style); // Apply the style to the paragraph paragraph.ApplyStyle(style.Name); // Set the horizontal alignment paragraph.Format.HorizontalAlignment = HorizontalAlignment.Left; // Save the document to a docx file doc.SaveToFile("SetFont.docx", FileFormat.Docx2019); // Dispose resources doc.Dispose(); } } }
Apply Different Fonts to Text in C#
In some cases, you may need to apply various fonts to different segments of the same paragraph. Spire.Doc offers the TextRange class, which allows you to assign distinct styles to specific text ranges within a paragraph. To do this, ensure that the text requiring different styles is organized into separate text ranges.
The steps to apply multiple fonts in a paragraph using C# are as follows:
- Create a Document object.
- Add a section and a paragraph to the document.
- Append text to the paragraph using the Paragraph.AppendText() method, which returns a TextRange object.
- Append more text that needs to be styled differently to the paragraph and return different TextRange objects.
- Create a ParagraphStyle object with the basic font information and apply it to the paragraph.
- Change the font name, style, size and text color of the specified text range using the properties under the specific TextRange object.
- Save the document to a Word file.
Here's an example that demonstrates how to apply different fonts to different parts of a paragraph:
- C#
using Spire.Doc; using Spire.Doc.Documents; using Spire.Doc.Fields; using System.Drawing; namespace ApplyDifferentFontsToText { class Program { static void Main(string[] args) { // Create a Document object Document doc = new Document(); // Add a section Section section = doc.AddSection(); // Set the page margins section.PageSetup.Margins.All = 40f; // Add a paragraph Paragraph paragraph = section.AddParagraph(); // Append text to the paragraph TextRange textRange1 = paragraph.AppendText("Spire.Doc for .NET"); TextRange textRange2 = paragraph.AppendText(" is a powerful library designed for developers " + "working with document processing in the .NET environment. It enables users to "); TextRange textRange3 = paragraph.AppendText("create, read, modify, and convert"); TextRange textRange4 = paragraph.AppendText(" various types of document formats, such as "); TextRange textRange5 = paragraph.AppendText("DOC, DOCX, PDF"); TextRange textRange6 = paragraph.AppendText(" and more, without the need for Microsoft Office installed on the machine."); // Create a ParagraphStyle object ParagraphStyle style = new ParagraphStyle(doc); // Set the style name style.Name = "myStyle"; // Set the font style, name, size and text color style.CharacterFormat.Bold = false; style.CharacterFormat.TextColor = Color.Black; style.CharacterFormat.FontName = "Times New Roman"; style.CharacterFormat.FontSize = 14; // Add the style the document doc.Styles.Add(style); // Apply the style to the paragraph paragraph.ApplyStyle(style.Name); // Change the font style of the specified text ranges textRange1.CharacterFormat.Bold = true; textRange1.CharacterFormat.TextColor = Color.Purple; textRange3.CharacterFormat.Bold = true; textRange3.CharacterFormat.TextColor = Color.Purple; textRange5.CharacterFormat.Bold = true; textRange5.CharacterFormat.TextColor = Color.Purple; // Set the horizontal alignment paragraph.Format.HorizontalAlignment = HorizontalAlignment.Left; // Save the document to a docx file doc.SaveToFile("ApplyDifferentFonts.docx", FileFormat.Docx2019); // Dispose resources doc.Dispose(); } } }
Use a Custom Font in a Word Document in C#
Spire.Doc supports custom fonts, allowing you to use fonts that are not installed on the system where the application is running. To use a custom font, you need to embed the font file in your application and then specify it in your code.
The steps to utilize custom fonts in a Word document are as follows:
- Create a Document object.
- Add a section and a paragraph to the document.
- Append text to the paragraph.
- Set the custom fonts for the document using the Document.SetCustomFonts() method.
- Embed fonts in the generated file by setting the Document.EmbedFontsInFile property to true.
- Create a ParagraphStyle object.
- Set the font name to your custom font using the ParagraphStyle.CharacterFormat.FontName property.
- Apply the style to the paragraph using the Paragraph.ApplyStyle() method.
- Save the document to a Word file.
Here's an example that demonstrates how to use a custom font:
- C#
using Spire.Doc; using Spire.Doc.Documents; using System.Drawing; namespace SetFontForParagraph { class Program { static void Main(string[] args) { // Create a Document object Document doc = new Document(); // Add a section Section section = doc.AddSection(); // Set the page margins section.PageSetup.Margins.All = 40f; // Add a paragraph Paragraph paragraph = section.AddParagraph(); // Append text to the paragraph paragraph.AppendText("Spire.Doc for .NET is a powerful library designed for developers " + "working with document processing in the .NET environment. It enables users to create, " + "read, modify, and convert various types of document formats, such as DOC, DOCX, PDF, " + "and more, without the need for Microsoft Office installed on the machine."); // Specify the private font path string fontPath = "C:\\Users\\Administrator\\Desktop\\Super Morning.ttf"; // Create an array of Stream objects to hold the font streams Stream[] fontStreams = new Stream[1]; fontStreams[0] = new FileStream(fontPath, FileMode.Open, FileAccess.Read); // Set the custom fonts for the document doc.SetCustomFonts(fontStreams); // Embed fonts in the generated file doc.EmbedFontsInFile = true; // Create a ParagraphStyle object ParagraphStyle style = new ParagraphStyle(doc); // Set the paragraph style name style.Name = "myStyle"; // Set the font name as the name of the private font style.CharacterFormat.FontName = "Super Morning"; // Set the font style, size and text color style.CharacterFormat.Bold = false; style.CharacterFormat.TextColor = Color.Black; style.CharacterFormat.FontSize = 14; // Add the style the document doc.Styles.Add(style); // Apply the defined style to the paragraph paragraph.ApplyStyle(style.Name); // Set the horizontal alignment paragraph.Format.HorizontalAlignment = HorizontalAlignment.Left; // Save the document to a docx file doc.SaveToFile("UseCustomFont.docx", FileFormat.Docx2019); // Dispose resources doc.Dispose(); } } }
