How do I get a text style name?

I set 2 lines of text as “title1” style and 2 lines of text as “body1” style in word, but with the name that cannot get the style, this is code:
Debug.WriteLine(“style:” + paragraph.ParagraphFormat.Style.Name);

Output result:Normal

the result is “Normal”, the result I want to get is title1 or body1, how to solve it?

@lovecomputer Unfortunately, I cannot preproduce the problem on my side. The following code properly returns paragraph style names applied to paragraphs in the attached document:

Document doc = new Document(@"C:\Temp\in.docx");
    
foreach(Paragraph p in doc.FirstSection.Body.Paragraphs)
    Console.WriteLine(p.ParagraphFormat.StyleName);

output is the following:

title1
title1
body1
body1
Normal
