Step 1: Setting Up the Project

Before you can add password protection to your document, you need to set up your project. Let’s get started.

Create a New Project

Open Visual Studio and create a new C# Console Application. Name it something memorable, like “WordDocumentProtection.”

Install Aspose.Words for .NET

You can install Aspose.Words for .NET via NuGet Package Manager. Right-click on your project in the Solution Explorer, select “Manage NuGet Packages,” and search for “Aspose.Words.” Install the package.

Install-Package Aspose.Words

Step 2: Load or Create a Word Document

Now that our project is set up, let’s create a Word document that we can protect.

In your Program.cs file, initialize a new instance of the Document class. This class represents the Word document you’ll be working with.

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();

Step 3: Apply Password Protection

This is where the magic happens. We’ll apply password protection to our document to prevent unauthorized access.

Choose Protection Type

Aspose.Words offers different types of protection, such as NoProtection, ReadOnly, AllowOnlyComments, and AllowOnlyFormFields. For this example, we’ll use NoProtection but with a password, which essentially means the document is editable but requires a password to remove protection.

Apply Protection

Use the Protect method of the Document class to apply password protection.

// Apply document protection.
doc.Protect(ProtectionType.NoProtection, "password");

Step 4: Save the Protected Document

Finally, let’s save our protected document to a specified directory.

Use the Save method to save your document. Provide the path where you want to save the document along with the filename.

doc.Save(dataDir + "DocumentProtection.PasswordProtection.docx");

Conclusion

And there you have it! You’ve successfully added password protection to your Word document using Aspose.Words for .NET. It’s like having a digital lock on your most important documents, ensuring they’re safe from prying eyes.
