Word.List list = doc.Lists.Add(range, Word.WdListType.wdListOutlineNumbered);
Word.ListLevel level = list.ListLevels[1];
level.NumberFormat = "%1.";
level.TrailingCharacter = Word.WdTrailingCharacter.wdTrailingTab;
level.NumberStyle = Word.WdListNumberStyle.wdListNumberStyleArabic;

// 在数字列表的段落后面添加用项目符号的段落
Word.Paragraph para = doc.Content.Paragraphs.Add();
para.Range.InsertAfter("This is a paragraph with a bullet point.");
para.Range.ListFormat.ApplyBulletDefault(Word.WdDefaultListBehavior.wdWord10ListBehavior);
para.Range.InsertParagraphAfter();
