  <p>I want to change the style of the predefined built-in style by running the C# code below.</p>
  
  <pre><code>        // open document
          Object oFilePath = "C://Users/myDoc.docx";   
          Microsoft.Office.Interop.Word._Document myDoc;
          myDoc = wrdApp.Documents.Open(ref oFilePath, ref oMissing,
                              ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                              ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                              ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                              ref oMissing, ref oMissing
                         );
          // Change header2 style
          myDoc.Styles[WdBuiltinStyle.wdStyleHeading2].Font.Color = WdColor.wdColorOrange;
  
  
          //save and close doc
          myDoc.Save();
          Object oFalse = false;
          myDoc.Close(ref oFalse, ref oMissing, ref oMissing);
  </code></pre>
  
  <p>The code successfully change the color of heading text, but the number before the text still remains green, not affected by the code. Like the following picture.</p>
