Examples

Shows how to protect a document with a password.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("Hello world! This document is protected.");
// Enter a password up to 15 characters in length, and then verify the document's protection status.
doc.WriteProtection.SetPassword("MyPassword");
doc.WriteProtection.ReadOnlyRecommended = true;

Assert.IsTrue(doc.WriteProtection.IsWriteProtected);
Assert.IsTrue(doc.WriteProtection.ValidatePassword("MyPassword"));

// Protection does not prevent the document from being edited programmatically, nor does it encrypt the contents.
doc.Save(ArtifactsDir + "Document.WriteProtection.docx");
doc = new Document(ArtifactsDir + "Document.WriteProtection.docx");

Assert.IsTrue(doc.WriteProtection.IsWriteProtected);

builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
builder.Writeln("Writing text in a protected document.");

Assert.AreEqual("Hello world! This document is protected." +
                "\rWriting text in a protected document.", doc.GetText().Trim());
