Image image = Image.FromFile("image.jpg");

//specify the paragraph
Paragraph paragraph = document.Sections[0].Paragraphs[2];
DocPicture picture = paragraph.AppendPicture(image);

//resize the image
picture.Height = picture.Height * 0.8f;

document.SaveToFile("result.docx", FileFormat.Docx);

3. 問：如何對齊word文件中的文字？

答：請設定段落的屬性HorizontalAlignment以對齊文字。完整程式碼：

Document document = new Document();
document.LoadFromFile("sample.docx");

//set paragraph1 to align left
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;

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

4. 問：如何更改現有書籤上的文字？

答：您可以使用BookmarksNavigator來查詢指定的書籤。然後請呼叫ReplaceBookmarkContent方法替換書籤上的文字。完整程式碼：

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");

9. 問：如何合併word文件？

答：請呼叫克隆方法複製一節。然後呼叫Add方法將該部分的副本新增到指定的文件。完整程式碼：

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");

10. 問：如何遍歷word文件中表格的單元格？

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++;
    }
}

11. 問：如何設定陰影文字？

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");

12. 問：如何在Word中插入行號？

答：您需要設定節的屬性LineNumberingRestartMode，LineNumberingStep，LineNumberingStartValue以在Word文件中插入行號。完整程式碼：

//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");

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.

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");

15. 問：如何設定超連結的格式不帶下劃線？

答：請設定超連結欄位的textRange節點來格式化超連結。完整程式碼：
