Word文档中的页眉和页脚用于格式化和显示重要信息，例如主题，章节，页码，Copywrite等。以编程方式使用Word文档时，可能需要添加或删除页眉和页脚。为此，本文将教您如何使用C ++在Word文档中添加和删除页眉和页脚。

让我们探索以下有关的内容：

• 使用C ++在Word文档中添加页眉和页脚
• 使用C ++删除Word文档中的页眉和页脚

要在Word文档中添加页眉和页脚，我们将使用Aspose.Words for C ++ 它是本机C ++ API，支持创建，读取和修改Word文档，而无需安装Microsoft Word。

使用C ++在Word文档中添加页眉和页脚

Word文档中的页眉和页脚分为三部分，标题页，偶数页和奇数页。可以为这些部分添加不同的页眉和页脚。此外，还可以在页眉和页脚中添加图像和表格之类的元素。

在此示例中，我们将创建一个新的Word文档，并为标题页添加一个不同的标题。我们将在后面的页面中添加带有图片的页眉和带有表格的页脚。以下是在Word文档中添加页眉和页脚的步骤。

• 创建Document类的实例来表示Word文档。
• 使用 先前创建的Document对象创建DocumentBuilder类 的实例 。
• 使用PageSetup-> set_DifferentFirstPageHeaderFooter（bool value）方法指定标题页面需要不同的页眉和页脚。
• 设置标题文本的字体属性。
• 为后续页面创建页眉和页脚。
• 使用DocumentBuilder->InsertImage(System::SharedPtrimage, Aspose::Words::Drawing::RelativeHorizontalPosition horzPos, double left, Aspose::Words::Drawing::RelativeVerticalPosition vertPos, double top, double width, double height, Aspose::Words::WrapType wrapType) 方法将图片加入页眉。
• 在页脚中添加表格。
• 使用Document->Save(System::String fileName)方法保存Word文档。

下面的示例代码演示了如何使用C ++在Word文档中添加页眉和页脚。

void CopyHeadersFootersFromPreviousSection(const System::SharedPtr& section)
{System::SharedPtrpreviousSection = System::DynamicCast(section->get_PreviousSibling());if (previousSection == nullptr){return;}section->get_HeadersFooters()->Clear();for (System::SharedPtrheaderFooterNode : System::IterateOver(previousSection->get_HeadersFooters())){section->get_HeadersFooters()->Add(headerFooterNode->Clone(true));}
}int main()
{// Source and output directory paths.System::String inputDataDir = u"SourceDirectory\\";System::String outputDataDir = u"OutputDirectory\\";System::SharedPtrdoc = System::MakeObject();System::SharedPtrbuilder = System::MakeObject(doc);System::SharedPtrcurrentSection = builder->get_CurrentSection();System::SharedPtrpageSetup = currentSection->get_PageSetup();// Specify if we want headers/footers of the first page to be different from other pages.// You can also use PageSetup.OddAndEvenPagesHeaderFooter property to specify// Different headers/footers for odd and even pages.pageSetup->set_DifferentFirstPageHeaderFooter(true);// --- Create header for the first page. ---pageSetup->set_HeaderDistance(20);builder->MoveToHeaderFooter(HeaderFooterType::HeaderFirst);builder->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Center);// Set font properties for header text.builder->get_Font()->set_Name(u"Arial");builder->get_Font()->set_Bold(true);builder->get_Font()->set_Size(14);// Specify header title for the first page.builder->Write(u"Aspose.Words Header/Footer Creation Primer - Title Page.");// --- Create header for pages other than the first page. ---pageSetup->set_HeaderDistance(20);builder->MoveToHeaderFooter(HeaderFooterType::HeaderPrimary);// Insert absolutely positioned image into the top/left corner of the header.// Distance from the top/left edges of the page is set to 10 points.System::String imageFileName = inputDataDir + u"Desert.jpg";builder->InsertImage(imageFileName, RelativeHorizontalPosition::Page, 10, RelativeVerticalPosition::Page, 10, 50, 50, WrapType::Through);builder->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Right);// Specify header title for other pages.builder->Write(u"Aspose.Words Header/Footer Creation Primer.");// --- Create footer for pages other than the first page. ---builder->MoveToHeaderFooter(HeaderFooterType::FooterPrimary);// We use table with two cells to make one part of the text on the line (with page numbering)// To be aligned left, and the other part of the text (with copyright) to be aligned right.builder->StartTable();// Clear table borders.builder->get_CellFormat()->ClearFormatting();builder->InsertCell();// Set the first cell to 1/3 of the page width.builder->get_CellFormat()->set_PreferredWidth(PreferredWidth::FromPercent(100 / 3));// Insert page numbering text here.// It uses PAGE and NUMPAGES fields to auto calculate current page number and total number of pages.builder->Write(u"Page ");builder->InsertField(u"PAGE", u"");builder->Write(u" of ");builder->InsertField(u"NUMPAGES", u"");// Align this text to the left.builder->get_CurrentParagraph()->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Left);builder->InsertCell();// Set the second cell to 2/3 of the page width.builder->get_CellFormat()->set_PreferredWidth(PreferredWidth::FromPercent(100 * 2 / 3));builder->Write(u"(C) 2001 Aspose Pty Ltd.

}

使用C ++删除Word文档中的页眉和页脚

与添加类似，可以根据需要从标题，偶数和奇数页中删除页眉和页脚。以下是删除Word文档中所有页眉和页脚的步骤。

• 使用Document类加载Word文档。
• 创建HeaderFooter类的两个实例以表示页眉和页脚。
• 使用Section-> get_HeadersFooters（）-> idx_get（Aspose :: Words :: HeaderFooterType headerFooterType）方法检索标题，偶数页和奇数页的页眉和页脚。
• 使用HeaderFooter-> Remove（）方法删除页眉和页脚。
• 使用Document-> Save（System :: String fileName）方法保存Word文档 。

下面的示例代码显示了如何使用C ++删除Word文档中的所有页眉和页脚。

// Source and output directory paths.
System::String inputDataDir = u"SourceDirectory\\";
System::String outputDataDir = u"OutputDirectory\\";System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"SampleHeaderFooter.docx");for (System::SharedPtr<Section> section : System::IterateOver<System::SharedPtr<Section>>(doc))
{// Up to three different header and footers are possible in a section (for first, even and odd pages).// We check and delete all of them.System::SharedPtr<HeaderFooter> header;System::SharedPtr<HeaderFooter> footer;header = section->get_HeadersFooters()->idx_get(HeaderFooterType::HeaderFirst);footer = section->get_HeadersFooters()->idx_get(HeaderFooterType::FooterFirst);if (header != nullptr){header->Remove();}if (footer != nullptr){footer->Remove();}// Primary header and footer is used for odd pages.header = section->get_HeadersFooters()->idx_get(HeaderFooterType::HeaderPrimary);footer = section->get_HeadersFooters()->idx_get(HeaderFooterType::FooterPrimary);if (header != nullptr){header->Remove();}if (footer != nullptr){footer->Remove();}header = section->get_HeadersFooters()->idx_get(HeaderFooterType::HeaderEven);footer = section->get_HeadersFooters()->idx_get(HeaderFooterType::FooterEven);if (header != nullptr){header->Remove();}if (footer != nullptr){footer->Remove();}
}// Output file path
System::String outputPath = outputDataDir + u"RemoveFooters.docx";// Save the document.
doc->Save(outputPath);
