Aspose.Words 将word2中的内容插入到word1中的指定位置

将word2中的内容插入到word1中的指定位置（经测试可用）

在官网找到的例子，记录一下：

        public static void insertdocumentatbookmark(string datadir)
        {
            document maindoc = new document(datadir + "insertdocument1.doc");
            document subdoc = new document(datadir + "insertdocument2.doc");

            //定位到书签：insertionplace
            bookmark bookmark = maindoc.range.bookmarks["insertionplace"];
            //将subdoc中的内容插入到maindoc中的书签“insertionplace”位置
            insertdocument(bookmark.bookmarkstart.parentnode, subdoc);
            datadir = datadir + "insertdocumentatbookmark_out.doc";
            maindoc.save(datadir);
        }

        /// <summary>
        /// 在指定节点之后插入外部文档的内容。
        /// 插入文档的分节符和节格式将被忽略。
        /// </summary>
