如何让WebServer返回指的定XML内容?

发布时间:2019-09-13 20:39:18

通过创建WEBServer代理可以当作本地类使用,但能不能返回指定的XML呢?

比如通过checkpass服务检测帐号和密码之后要返回该用户拥有的权限列表。怎么实现呢?

研究中........

请各大侠指点

asp_net高级编程928页19.4.2 数据类型

ASP.NET Web服务支持在公共语言运行时中支持的所有基本数据类型,包括String,integer,Long等等。除了简单的基本数据类型之外,还支持基本数据类型的数组。

但是,更有趣的是支持用户定义的类和结构体。基本上,任何可由XSD模式代表的类型都是可以作为ASP.NET的参数或返回类型。

通过一个星期的摸索,解决了这个问题,并学习了如何读取和输出XML文档;数据库操作;WebServer的创建和引用。下面就部分源码供初学习者参考,不足之此请指正。
