WebService 服务可以返回任何可序列化的对象.doc

WebService 服务可以返回任何可序列化的对象.本文代码给出返回基本数据类型及实体类结构示例和调用代码示例.WebService代码如下: 1.using System; 2.using System.Collections; 3.using System.ComponentModel; 4.using System.Data; 5.using System.Diagnostics; 6.using System.Web; 7.using System.Web.Services; 8.namespace StudentServer 9. 10. / 11. / 本类实现WebService服务 12. / 提供对各种数据类型的返回例子 13. / 包括: 14. / 基本数据类型(string,ini,bool,long,float等) 15. / 类结构型(class),必须是可序列化的类 16. / DataSet类型 17. / 18. public class Demo : System.Web.Services.WebService 19. 20. public Demo() 21. 22. /CODEGEN: 该调用是 ASP.NET Web 服务设计器所必需的 23.
