2 mins read

Syncfusion Essential DocIO is a .NET Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can find the list of fonts used in the Word document.

Steps to find the list of fonts used in the Word document programmatically:

  1. Create a new C# console application project.

    Graphical user interface, application

Description automatically generated

  2. Install the Syncfusion.DocIO.Winforms NuGet package as a reference to your .NET Framework applications from NuGet.org.

    Graphical user interface, text, application, email

Description automatically generated

  3. Include the following namespace in the Program.cs file.

C#

using Syncfusion.DocIO;


using Syncfusion.DocIO.DLS;

 

VB.NET

Imports Syncfusion.DocIO


Imports Syncfusion.DocIO.DLS

 

  1. Use the following code example to find the list of fonts used in the Word document.


//Open the template document.


WordDocument wordDocument = new WordDocument(@"../../Data/Adventure.docx", FormatType.Docx);


//Get the list of fonts used in current Word document.


List<Font> usedFontsCollection = GetUsedFontsList(wordDocument);


Console.WriteLine("List of fonts used in the Word document:");


foreach (Font usedFont in usedFontsCollection)


{


Console.WriteLine("Font name : " + usedFont.Name + "; Bold : " + usedFont.Bold + "; Italic : " + usedFont.Italic);


}


//Save word document.


wordDocument.Save("Output.docx");


wordDocument.Close();


Console.WriteLine("Press enter key to exit.");


Console.ReadKey();

VB.NET

' Open the template document.


Dim wordDocument As New WordDocument("../../Data/Adventure.docx", FormatType.Docx)


' Get the list of fonts used in the current Word document.


Dim usedFontsCollection As List(Of Font) = GetUsedFontsList(wordDocument)


Console.WriteLine("List of fonts used in the Word document:")


For Each usedFont As Font In usedFontsCollection


Console.WriteLine("Font name : " & usedFont.Name & "; Bold : " & usedFont.Bold & "; Italic : " & usedFont.Italic)


Next


' Save the Word document.


wordDocument.Save("Output.docx")


wordDocument.Close()


Console.WriteLine("Press enter key to exit.")


Console.ReadKey()
