Step 1: Create a Document

First things first, let’s create a new document. This is like getting a blank sheet of paper ready.

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

Explanation

  • dataDir: This variable stores the path where your document will be saved.
  • Document doc = new Document(): This line initializes a new document.
  • DocumentBuilder builder = new DocumentBuilder(doc): The DocumentBuilder is a handy tool for adding content to your document.

Step 2: Add Content

Now that we have our blank sheet, let’s write something on it. How about a simple “Hello world!”? Classic.

builder.Write("Hello world!");

Explanation

  • builder.Write(“Hello world!”): This line adds the text “Hello world!” to your document.

Step 3: Configure Save Options

Here comes the crucial part—configuring the save options to include password protection. This is where you decide the strength of your lock.

DocSaveOptions saveOptions = new DocSaveOptions { Password = "password" };

Explanation

  • DocSaveOptions saveOptions = new DocSaveOptions: Initializes a new instance of the DocSaveOptions class.
  • Password = “password”: Sets the password for the document. Replace “password” with your desired password.

Step 4: Save the Document

Finally, let’s save our document with the specified options. This is like storing your locked diary in a safe place.

doc.Save(dataDir + "WorkingWithDocSaveOptions.EncryptDocumentWithPassword.docx", saveOptions);

Explanation

  • doc.Save: Saves the document to the specified path with the defined save options.
  • dataDir + “WorkingWithDocSaveOptions.EncryptDocumentWithPassword.docx”: Constructs the full path and file name for the document.
