Spire.Doc基本操作，你會了嗎？（文檔管理控件技術交流：QQ群：767755948）

1. 問：如何從word文檔中獲取文本？

答：您可以調用方法method document.GetText（）來執行此操作。完整代碼：

document.LoadFromFile(@"..\..\test.docx");
using (StreamWriter sw = File.CreateText("output.txt"))
 {
 sw.Write(document.GetText());
 }
 

2. 問：如何插入具有指定高度和寬度的圖像？

答：您可以設置DocPicture的屬性高度和寬度來調整圖像大小。完整代碼：

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

3. 問：如何對齊word文檔中的文本？

答：請設置段落的屬性HorizontalAlignment以對齊文本。完整代碼：

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;

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

4. 問：如何更改現有書簽上的文字？

答：您可以使用BookmarksNavigator來查找指定的書簽。然后請調用ReplaceBookmarkContent方法替換書簽上的文本。完整代碼：

Document document = new Document();
document.LoadFromFile("sample.doc");
BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document);
bookmarkNavigator.MoveToBookmark("mybookmark");

//replace text on bookmarks
bookmarkNavigator.ReplaceBookmarkContent("new context", false);
document.SaveToFile("result.doc", FileFormat.Doc);

5. 問：如何將word轉換為html？

答：您可以使用指定的文件格式HTML調用SaveToFile方法將word文檔轉換為html。完整代碼：

document.LoadFromFile("sample.doc");

//save word document as html file
document.SaveToFile("result.html", FileFormat.Html);
document.Close();

6. 問：如何將html轉換為word文檔？

答：請調用LoadFromFile方法加載html文件。然后調用SaveToFile方法將html轉換為word文檔。完整代碼：

Document document = new Document();

document.LoadFromFile("sample.html", FileFormat.Html, XHTMLValidationType.None);
//save html as word document
document.SaveToFile("result.doc");

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

8. 問：如何替換和刪除Word文檔中的頁眉或頁腳？

答：請使用Section獲取頁眉或頁腳。您可以調用替換方法來替換標題并調用Clear方法以刪除Word文檔的頁眉或頁腳。

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");

9. 問：如何合并word文檔？

答：請調用克隆方法復制一節。然后調用Add方法將該部分的副本添加到指定的文檔。完整代碼：

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");

10. 問：如何遍歷word文檔中表格的單元格？

答：行是表中行的集合，單元是行中單元的集合。所以你可以用兩個循環來遍歷表格的單元格。完整代碼：

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：如何設置陰影文字？

答：您只需設置TextRange的屬性IsShadow即可。完整代碼：

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");

12. 問：如何在Word中插入行號？

答：您需要設置節的屬性LineNumberingRestartMode，LineNumberingStep，LineNumberingStartValue以在Word文檔中插入行號。完整代碼：

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");

13. 問：如何使圖像周圍的文字？

答：您需要設置圖片的屬性TextWrappingStyle和ShapeHorizontalAlignment。完整代碼：

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");

14. 問：如何編輯Word文檔中的現有表？

答：使用Section獲取表格，您可以編輯單元格中的文本，并且可以將新行插入到表格中。完整代碼：

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");

15. 問：如何設置超鏈接的格式不帶下劃線？

答：請設置超鏈接字段的textRange節點來格式化超鏈接。完整代碼：

Document document = new Document();
Section section = document.AddSection();
Paragraph paragraph = section.AddParagraph();
Field hyperlink = paragraph.AppendHyperlink("www.e-iceblue.com", "www.e-iceblue.com", HyperlinkType.WebLink);
