3. Include the following namespaces in Program.cs file
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;

4. Use the following code example to change the font for specific content in a Word document.
   C#

using (FileStream inputStream = new FileStream(Path.GetFullPath(@"Data/Input.docx"), FileMode.Open, FileAccess.Read))
{
   //Open an existing Word document.
   using (WordDocument document = new WordDocument(inputStream, FormatType.Docx))
   {
       //Find all the paragraphs based on specific style name.
       List<Entity> paragraphs = document.FindAllItemsByProperty(EntityType.Paragraph, "StyleName", "List Paragraph");
       //Iterate through each paragraph.
       foreach (WParagraph paragraph in paragraphs)
       {
           //Iterate through each child items in the paragraph.
           foreach (Entity childItem in paragraph.ChildEntities)
           {
               //Check if entity is WTextRange.
               if (childItem is WTextRange)
               {
                   WTextRange textRange = childItem as WTextRange;
                   //Change the font name for the text range.
                   textRange.CharacterFormat.FontName = "Algerian";
               }
           }
       }
       //Create output file stream.
       using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.OpenOrCreate, FileAccess.ReadWrite))
       {
           //Save the modified Word document.
           document.Save(outputStream, FormatType.Docx);
       }
   }
}
