例子

展示如何使用文档访问者打印所有注释的内容及其注释范围。

public void CreateCommentsAndPrintAllInfo()
{
    Document doc = new Document();

    Comment newComment = new Comment(doc)
    {
        Author = "VDeryushev",
        Initial = "VD",
        DateTime = DateTime.Now
    };

    newComment.SetText("Comment regarding text.");

    // 将文本添加到文档中，将其扭曲到注释范围内，然后添加您的注释。
    Paragraph para = doc.FirstSection.Body.FirstParagraph;
    para.AppendChild(new CommentRangeStart(doc, newComment.Id));
    para.AppendChild(new Run(doc, "Commented text."));
    para.AppendChild(new CommentRangeEnd(doc, newComment.Id));
    para.AppendChild(newComment); 

    // 添加两条对评论的回复。
    newComment.AddReply("John Doe", "JD", DateTime.Now, "New reply.");
    newComment.AddReply("John Doe", "JD", DateTime.Now, "Another reply.");

    PrintAllCommentInfo(doc.GetChildNodes(NodeType.Comment, true));
}
