We’ll guide you through each step, from importing namespaces to writing the code for password protection.

Prerequisites

Before getting started, ensure you have the following:

• Basic knowledge of C# programming language.
• Visual Studio installed on your system.
• Aspose.Note for .NET installed. You can download it from here.

Import Namespaces

First, let’s import the necessary namespaces to access the functionality of Aspose.Note for .NET.

using System.IO;
using Aspose.Note;
using Aspose.Note.Saving;
using System;
using System.Drawing;
using System.Globalization;

Step 1: Load the Notebook

// The path to the documents directory.
string dataDir = "Your Document Directory";

// Load the notebook
var notebook = new Notebook(dataDir + "test.onetoc2", new NotebookLoadOptions() { DeferredLoading = false });

Step 2: Save the Notebook

// Save the notebook
notebook.Save(dataDir + "notebook_out.onetoc2", new NotebookOneSaveOptions() { DeferredSaving = true});

Step 3: Check if Notebook Has Child Documents

if (notebook.Any())

Step 4: Access Child Documents and Save with Password Protection

// Access child documents
var childDocument0 = notebook[0] as Document;
var childDocument1 = notebook[1] as Document;
var childDocument2 = notebook[2] as Document;

// Save child documents with password protection
childDocument0.Save(dataDir + "Not Locked_out.one");

childDocument1.Save(dataDir + "Locked Pass1_out.one", new OneSaveOptions() { DocumentPassword = "pass" });

childDocument2.Save(dataDir + "Locked Pass2_out.one", new OneSaveOptions() { DocumentPassword = "pass2" });
