Hi Prashant,

Thanks for your inquiry. You are getting the exception because there is no custom style in empty document with name ‘Cover Document Title’. Following code example shows how to create custom style. Hope this helps you.

Aspose.Words.Document wordDoc = new Aspose.Words.Document();
Style style = wordDoc.Styles.Add(StyleType.Character, "Cover Document Title");
style.Font.Size = 24;
style.Font.Name = "Verdana";

wordDoc.RemoveAllChildren();
Aspose.Words.Section wordSection = new Aspose.Words.Section(wordDoc);
wordSection.PageSetup.SectionStart = SectionStart.Continuous;
wordDoc.Sections.Add(wordSection);

Body body = new Body(wordDoc);
wordSection.PageSetup.TopMargin = 42.0f;
wordSection.PageSetup.LeftMargin = 56.0f;
wordSection.PageSetup.BottomMargin = 72.0f;
wordSection.PageSetup.RightMargin = 72.0f;
wordSection.PageSetup.DifferentFirstPageHeaderFooter = true;
wordSection.PageSetup.HeaderDistance = 20;

Aspose.Words.Paragraph para1 = new Aspose.Words.Paragraph(wordDoc);
// listpara1.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
// listpara1.ParagraphFormat.StyleName = "Cover Document Title";
Run textSegment = new Run(wordDoc);
textSegment.Text = "First paragraph";
textSegment.Font.Size = 12;
// textSegment.Font.StyleIdentifier = StyleIdentifier.;
textSegment.Font.StyleName = "Cover Document Title";
para1.AppendChild(textSegment);
body.AppendChild(para1);

wordSection.AppendChild(body);
wordDoc.Save(MyDir + "Out.docx");
