//set paragraph3 to align right
Paragraph paragraph3 = document.Sections[0].Paragraphs[2];
paragraph3.Format.HorizontalAlignment = HorizontalAlignment.Right;
document.SaveToFile("result.docx");

Q.如何更改現有書籤的文字？

A：您能夠使用BookmarksNavigator找到指定的書籤。 而後請使用ReplaceBookmarkContent方法替換書籤上的文字。所有代碼：

HeaderFooter header = section.HeadersFooters.Header;
Paragraph headerParagraph = header.AddParagraph();
TextRange text = headerParagraph.AppendText("Demo of Spire.Doc");
text.CharacterFormat.TextColor = Color.Blue;

section.PageSetup.LineNumberingStep = 1;
section.PageSetup.LineNumberingStartValue = 1;
Paragraph paragraph = section.AddParagraph();
paragraph.AppendText("As an independent Word .NET component, Spire.Doc for .NET doesn't need Microsoft Word to be installed on the machine. However, it can incorporate Microsoft Word document creation capabilities into any developers .NET applications.");

p1.Text = "abc";

TableCell cell2 = table.Rows[1].Cells[2];
Paragraph p2 = cell2.Paragraphs[0];
p2.Items.Clear();
p2.AppendText("def");

TableCell cell3 = table.Rows[1].Cells[3];
Paragraph p3 = cell3.Paragraphs[0];
(p3.Items[0] as TextRange).Text = "hij";

//insert new row
TableRow newRow = table.AddRow(true, true);
foreach (TableCell cell in newRow.Cells)
{
    cell.AddParagraph().AppendText("new row");

doc.SaveToFile("result.doc");

Q.如何設置無下劃線的超連接格式？

A：請將超連接字段的textRange節點設置爲超連接格式。所有代碼：
