picture.Width = picture.Width * 0.8f;
document.SaveToFile("result.docx", FileFormat.Docx);

Q.如何在word文档中对齐文本？

A：请设置段落的HorizontalAlignment属性以对齐文本。 所有代码：

Document document = new Document();

Paragraph paragraph1 = document.Sections[0].Paragraphs[0];
paragraph1.Format.HorizontalAlignment = HorizontalAlignment.Left;

//set paragraph2 to align center
Paragraph paragraph2 = document.Sections[0].Paragraphs[1];
paragraph2.Format.HorizontalAlignment = HorizontalAlignment.Center;

//set paragraph3 to align right
Paragraph paragraph3 = document.Sections[0].Paragraphs[2];
paragraph3.Format.HorizontalAlignment = HorizontalAlignment.Right;

document.Close();

Q.如何将html转换成word文档？

A：请调用LoadFromFile方法加载html文件。 而后调用SaveToFile方法将html转换为word文档。所有代码：

Q.如何将word2007转换为word2003？

A：只需使用指定的文件格式doc调用SaveToFile方法将word2007转换为word2003。所有代码：

Document document = new Document("word2007.docx");

//convert word2007 to word2003
document.SaveToFile("word2003.doc", FileFormat.Doc);
document.Close();

Q.如何在word文档中替换和删除页眉或页脚？

A：请使用Section来获取页眉或页脚。 而且您能够调用Replace替换页眉并调用Clear方法来删除word文档的页眉或页脚。

Document document = new Document();
Section section = document.AddSection();

//add a header
HeaderFooter header = section.HeadersFooters.Header;
Paragraph headerParagraph = header.AddParagraph();
TextRange text = headerParagraph.AppendText("Demo of Spire.Doc");
text.CharacterFormat.TextColor = Color.Blue;
document.SaveToFile("DocWithHeader.doc");

//replace the header
headerParagraph.Replace("Demo", "replaceText", true, true);
document.SaveToFile("DocHeaderReplace.doc");
document.LoadFromFile("DocWithHeader.doc");

//delete the heater
document.Sections[0].HeadersFooters.Header.Paragraphs.Clear();
document.SaveToFile("DocHeaderDelete.doc");

Q.如何合并Word？

A：请调用克隆方法复制部分，而后调用方法Add将该部分的副本添加到指定的文档。所有代码：

Document document1 = new Document();
document1.LoadFromFile("merge1.docx");
Document document2 = new Document();
document2.LoadFromFile("merge2.docx");

//add sections from document1 to document2
foreach (Section sec in document2.Sections)
{
    document1.Sections.Add(sec.Clone());
}
document1.SaveToFile("result.docx");

Q.如何遍历Word文档中的表单元格？

A：Rows是表中行的集合，Cells是行中的单元格集合。 所以，您能够使用两个循环遍历表的单元格。所有代码：

Document document = new Document();
document.LoadFromFile("sample.docx");
Spire.Doc.Interface.ITable table = document.Sections[0].Tables[0];
int i=0;

//traverse the cells
foreach (TableRow row in table.Rows)
{
    foreach (TableCell cell in row.Cells)
    {
        i++;
    }
}

Q.如何用阴影设置文字？

A：您只须要设置TextRange的属性IsShadow。所有代码：

Document document = new Document();
Section section = document.AddSection();
Paragraph paragraph = section.AddParagraph();
TextRange HText = paragraph.AppendText("this is a test!");

//set the property IsShadow
HText.CharacterFormat.IsShadow = true;
HText.CharacterFormat.FontSize = 80;
document.SaveToFile("result.doc");

Q.如何在Word中插入行号？

A：您须要设置该段的属性LineNumberingRestartMode，LineNumberingStep，LineNumberingStartValue，以在word文档中插入行号。所有代码：

Document document = new Document();
Section section = document.AddSection();

//insert line numbers
section.PageSetup.LineNumberingRestartMode = LineNumberingRestartMode.RestartPage;
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.");
document.SaveToFile("result.doc");

Q.如何设置图像周围的文字？

A：您须要设置图片的属性TextWrappingStyle和ShapeHorizontalAlignment。所有代码：

Document document = new Document();
Section section = document.AddSection();
Paragraph paragraph = section.AddParagraph();
string str = "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.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.";
paragraph.AppendText(str);
DocPicture picture = paragraph.AppendPicture(Image.FromFile("logo.png"));
picture.TextWrappingStyle = TextWrappingStyle.Tight;
picture.HorizontalAlignment = ShapeHorizontalAlignment.Center;
document.SaveToFile("result.doc");

Q.如何编辑word文档中的现有表？

A：使用Section获取表，您能够编辑单元格中的文本，而且能够在表中插入新行。所有代码：

Document doc = new Document("sample.docx");
Section section = doc.Sections[0];
ITable table = section.Tables[0];

//edit text in a cell
TableCell cell1 = table.Rows[1].Cells[1];
Paragraph p1 = cell1.Paragraphs[0];
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.如何设置无下划线的超连接格式？

A：请将超连接字段的textRange节点设置为超连接格式。所有代码：

Section section = document.AddSection();
Paragraph paragraph = section.AddParagraph();
Field hyperlink = paragraph.AppendHyperlink("www.e-iceblue.com", "www.e-iceblue.com", HyperlinkType.WebLink);
TextRange text = hyperlink.NextSibling.NextSibling as TextRange;
text.CharacterFormat.Bold = true;
text.CharacterFormat.UnderlineStyle = UnderlineStyle.None;
document.SaveToFile("result.doc");

Q.如何设置单词文档只读？

A：请调用“保护”方法设置ProtectionType。所有代码：
