开发人员可以仅需要一个GemBox.Document多文档处理控件就可以在您的.NET应用程序中对DOCX, DOC, PDF, HTML, XPS, RTF 和TXT等文件进行读取、写入转换和打印，并且使用简单，开发人员可以快速上手，大量节约项目的开发周期和成本，以及极大减少项目开发的风险，这篇文档主要介绍怎么在Word文件中创建多层目录结构TOC，具体可以参考下面的代码：
using System;
using System.IO;
using System.Linq;
using GemBox.Document;
using GemBox.Document.Drawing;
class Sample
{
[STAThread]
static void Main(string[] args)
{
// If using Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");
DocumentModel document = new DocumentModel();
int heading1Count = 3;
int heading2Count = 5;
// Create and add Heading 1 style.
ParagraphStyle heading1Style = (ParagraphStyle)Style.CreateStyle(StyleTemplateType.Heading1, document);
document.Styles.Add(heading1Style);
// Create and add Heading 2 style.
ParagraphStyle heading2Style = (ParagraphStyle)Style.CreateStyle(StyleTemplateType.Heading2, document);
document.Styles.Add(heading2Style);
// Create and add TOC style.
ParagraphStyle tocHeading = (ParagraphStyle)Style.CreateStyle(StyleTemplateType.Heading1, document);
tocHeading.Name = "toc";
tocHeading.ParagraphFormat.OutlineLevel = OutlineLevel.BodyText;
document.Styles.Add(tocHeading);
Section section = new Section(document);
document.Sections.Add(section);
// Add TOC title.
section.Blocks.Add(
new Paragraph(document, "Contents")
{
ParagraphFormat =
{
Style = tocHeading
}
});
// Create and add new TOC.
section.Blocks.Add(
new TableOfEntries(document, FieldType.TOC));
section.Blocks.Add(
new Paragraph(document,
new SpecialCharacter(document, SpecialCharacterType.PageBreak)));
// Add document content.
for (int i = 0; i < heading1Count; i++)
{
// Heading 1
section.Blocks.Add(
new Paragraph(document, "Heading 1 (" + (i + 1) + ")")
{
ParagraphFormat =
{
Style = heading1Style
}
});
for (int j = 0; j < heading2Count; j++)
{
// Heading 2
section.Blocks.Add(
new Paragraph(document, String.Format("Heading 2 ({0}-{1})", i + 1, j + 1))
{
ParagraphFormat =
{
Style = heading2Style
}
});
// Heading 2 content.
section.Blocks.Add(
new Paragraph(document,
"GemBox.Document is a .NET component that enables developers to read, write, convert and print document files (DOCX, DOC, PDF, HTML, XPS, RTF and TXT) from .NET applications in a simple and efficient way."));
}
}
// Update TOC (TOC can be updated only after all document content is added).
var toc = (TableOfEntries)document.GetChildElements(true, ElementType.TableOfEntries).First();
toc.Update();
// Update TOC's page numbers.
// NOTE: This is not necessary when printing and saving to PDF, XPS or an image format.
// Page numbers are automatically updated in that case.
document.GetPaginator(new PaginatorOptions() { UpdateFields = true });
document.Save("TOC.docx");
}
}
