本实例中的实例功能有： 

1、 Aspose.Words.dll 插入模板指定域替换为文字或html标签，见1

2、Aspose.Words.dll 插入模板表格,使用的是邮件合并MailMerge功能,数据源是DataTable或List对象（将list转换成DataTable），见1和2

3、word转换Pdf文件，见1

4、将多个word输出文档合并成一个文档 ，见1

5、请求API 接口查询JSON数据 ，见3

6、翻页查询，T-SQL方法见2

1、准备工作：word模板，插入域

域插入方法：

1.1>WPS添加域，插入>>文档部件>>域>>邮件合并，见图一

1.2> Office Word添加域，插入>>文档部件>>域>>MergeField，见图二

2、效果图
