Aspose.Pdf可以帮助开发人员在创建PDF或者为存在的PDF文件添加TOC目录,控件提供的 Aspose.Pdf.Generator空间下的ListSection类可以用于创建TOC目录,并且控件还可以设置TOC目录结构的样式,以及线条的样式等,具体如何创建TOC目录可以参考下面的详细代码:
// For complete examples and data files, please go to https://github.com/aspose-pdf/Aspose.Pdf-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();
 
// Load an existing PDF files
Document doc = new Document(dataDir + "AddTOC.pdf");
 
// Get access to first page of PDF file
Page tocPage = doc.Pages.Insert(1);
 
// Create object to represent TOC information
TocInfo tocInfo = new TocInfo();
TextFragment title = new TextFragment("Table Of Contents");
title.TextState.FontSize = 20;
title.TextState.FontStyle = FontStyles.Bold;
 
// Set the title for TOC
tocInfo.Title = title;
tocPage.TocInfo = tocInfo;
 
// Create string objects which will be used as TOC elements
string[] titles = new string[4];
titles[0] = "First page";
titles[1] = "Second page";
titles[2] = "Third page";
titles[3] = "Fourth page";
for (int i = 0; i < 2; i++)
{
    // Create Heading object
    Aspose.Pdf.Heading heading2 = new Aspose.Pdf.Heading(1);
    TextSegment segment2 = new TextSegment();
    heading2.TocPage = tocPage;
    heading2.Segments.Add(segment2);
 
    // Specify the destination page for heading object
    heading2.DestinationPage = doc.Pages[i + 2];
 
    // Destination page
    heading2.Top = doc.Pages[i + 2].Rect.Height;
 
    // Destination coordinate
    segment2.Text = titles[i];
 
    // Add heading to page containing TOC
    tocPage.Paragraphs.Add(heading2);
}
dataDir = dataDir + "TOC_out_.pdf";
// Save the updated document
doc.Save(dataDir);
