How to List out Word Document Formats (ex: Bold, Italic, BoldItalic) using C#

Question

Let friends know if you have any idea. I need to list out all the formats in the word document using c#. I tried word to XML convert and then read XML file formats, but it's not working correctly. So can anyone help me?

I attached the picture below. I need list out like this.

You can use Microsoft.Office.Interop.Word to do this, a simple example:

        private void browseBtn_Click(object sender, EventArgs e)  
        {  
            string filePath = null;  
            using (OpenFileDialog openFileDialog = new OpenFileDialog())  
            {  
                openFileDialog.InitialDirectory = "d:\\";  
                openFileDialog.Filter = @"All Files|*.txt;*.docx;*.doc;";  
  
                openFileDialog.FilterIndex = 2;  
                openFileDialog.RestoreDirectory = true;  
  
                if (openFileDialog.ShowDialog() == DialogResult.OK)  
                {  
                    //Get the path of specified file  
                    filePath = openFileDialog.FileName;  
  
                    //Read the contents of the file into a stream  
                    var fileStream = openFileDialog.OpenFile();  
                }  
            }  
            Word.Application application = new Word.Application();  
            Document document = application.Documents.Open(filePath);  
            List<string> text = GeyText(document);  
            textBox1.Text = text[0];  
            textBox2.Text = text[1];  
            document.Close();  
            application.Quit();  
        }  
  
        private List<string> GeyText(Document document)  
        {  
            List<string> strings = new List<string>();  
            StringBuilder boldText = new StringBuilder();  
            StringBuilder italicText = new StringBuilder();  
            foreach (Range item in document.Words)  
            {  
                if (item.Bold == -1)  
                {  
                    boldText.Append(item.Text + Environment.NewLine);  
                }  
                if (item.Italic == -1)  
                {  
                    italicText.Append(item.Text + Environment.NewLine);  
                }  
            }  
            strings.Add(boldText.ToString());  
            strings.Add(italicText.ToString());  
  
            return strings;  
        }

Maybe you can use the OpenXmlSdk

Alternatively, you could try Spire.Doc to retrieve all style names used in a Word document. Below is the code snippet for your reference.

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System;
using System.Text.RegularExpressions;
namespace RetrieveStyleNames
{
    class Program
    {
        static void Main(string[] args)
        {
            Document doc = new Document();
            doc.LoadFromFile("Sample.docx");

            foreach (Section section in doc.Sections)
            {
                foreach (Paragraph paragraph in section.Paragraphs)
                {
                    foreach (DocumentObject docObject in paragraph.ChildObjects)
                    {
                        if (docObject.DocumentObjectType == DocumentObjectType.TextRange)
                        {
                            TextRange text = docObject as TextRange;
                            Console.WriteLine(text.StyleName);
                        }
                    }
                    Console.WriteLine();
                }
            }
        }
    }
}
