How to make WebServer return the specified XML content

A WEBServer proxy can be created as a local application, but can I return the specified XML? For example, after checking the account and password through the checkpass service, you must return the list of permissions owned by the user. How can this problem be achieved? ASP. NETWeb service supports

ASP. NET Web services support all basic data types supported during the runtime of public languages, including String, integer, and Long. In addition to simple basic data types, it also supports arrays of basic data types.

However, it is more interesting to support user-defined classes and Struct. Any types that can be represented by the XSD mode can be used as ASP. NET parameters or return types.

After a week of exploration, I solved this title and learned how to read and output XML documents, database control, and WebServer creation and reference. The following are some source code for the reference of beginners. if this is not enough, please correct me.
