Create Bookmark In Word Document with Aspose.Words for .NET

Introduction

Navigating large documents can be challenging, but bookmarks make it a breeze! This tutorial will guide you through creating bookmarks in a Word document using Aspose.Words for .NET. You’ll learn step-by-step how to set up your document, add bookmarks, and save it as a PDF. Let’s get started!

Prerequisites

Before diving in, ensure you have the following:

  1. Aspose.Words for .NET Library: Download and install it from here.
  2. Development Environment: Use Visual Studio or any .NET-compatible IDE.
  3. Basic C# Knowledge: Familiarity with C# programming concepts will be helpful.

Importing Namespaces

First, import the necessary namespaces to work with Aspose.Words:

using Aspose.Words;
using Aspose.Words.Saving;

Step 1: Set Up the Document and DocumentBuilder

Create a new document and initialize the DocumentBuilder, which allows you to add content and bookmarks.

string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Step 2: Create the Main Bookmark

To create a bookmark, you need to specify its start and end points. Here’s how to create a bookmark named “My Bookmark”:

builder.StartBookmark("My Bookmark");
builder.Writeln("Text inside the main bookmark.");
  • StartBookmark: Marks the beginning of the bookmark.
  • Writeln: Adds text within the bookmark.

Step 3: Create a Nested Bookmark

You can nest bookmarks for better organization. Here’s how to add “Nested Bookmark” inside “My Bookmark”:

builder.StartBookmark("Nested Bookmark");
builder.Writeln("Text inside the nested bookmark.");
builder.EndBookmark("Nested Bookmark");
  • Nesting allows you to create a hierarchical structure.
  • EndBookmark: Closes the current bookmark.

Step 4: Add Text Outside the Nested Bookmark

After creating the nested bookmark, continue adding content within the main bookmark:

builder.Writeln("Text after the nested bookmark.");
builder.EndBookmark("My Bookmark");

This ensures that the main bookmark includes both the nested bookmark and any additional text.

Step 5: Configure PDF Save Options

To include bookmarks in the PDF, configure the save options:

PdfSaveOptions options = new PdfSaveOptions();
options.OutlineOptions.BookmarksOutlineLevels.Add("My Bookmark", 1);
options.OutlineOptions.BookmarksOutlineLevels.Add("Nested Bookmark", 2);
  • PdfSaveOptions: Defines how the document is saved as a PDF.
  • BookmarksOutlineLevels: Sets the hierarchy of bookmarks in the PDF.

Step 6: Save the Document

Finally, save the document as a PDF:

doc.Save(dataDir + "WorkingWithBookmarks.CreateBookmark.pdf", options);

The Save method saves the document in the specified format and location, complete with bookmarks.
