Import Necessary Namespaces

To access the functionality of Aspose.Words, you need to import the required namespaces:

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

Step 1: Create a New Document

Let’s create a fresh document, similar to preparing a blank canvas for your artwork.

string dataDir = "YOUR DOCUMENTS DIRECTORY"; // Specify your path
Document doc = new Document(); // Initializes a new document
DocumentBuilder builder = new DocumentBuilder(doc); // Prepares to add content
  • dataDir: This variable holds the path where your document will be saved.
  • Document doc = new Document(): Initializes a new document.
  • DocumentBuilder builder = new DocumentBuilder(doc): Creates a builder to conveniently add content.

Step 2: Add Content

Now, let’s fill our document with some text. How about a classic “Hello, World!”?

builder.Write("Hello, World!");
  • builder.Write(“Hello, World!”): Adds the text “Hello, World!” to your document.

Step 3: Set Up Save Options for Password Protection

Now comes the critical part—configuring the save options to enable password protection.

DocSaveOptions saveOptions = new DocSaveOptions { Password = "yourPassword" }; // Set your password here
  • DocSaveOptions saveOptions = new DocSaveOptions: Creates an instance of DocSaveOptions to hold save configurations.
  • Password = “yourPassword”: Assigns the password to secure the document. Remember to replace this with your preferred password.

Step 4: Save the Document

Finally, let’s save the document using the configured options:

doc.Save(dataDir + "EncryptedDocument.docx", saveOptions);
  • doc.Save: Saves the document at the specified path with the defined password protection.
  • dataDir + “EncryptedDocument.docx”: Constructs the complete path and filename for your document.
