例子

演示如何使用密码保护文档。

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln("Hello world! This document is protected.");
// 输入长度不超过15个字符的密码，然后验证文档的保护状态。
doc.WriteProtection.SetPassword("MyPassword");
doc.WriteProtection.ReadOnlyRecommended = true;

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

// 保护不会阻止以编程方式编辑文档，也不会加密内容。
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());
