动态webservice和静态webservice

一、普通的静态调用方法，可更换URL地址

 

localhost.WebService ws = new localhost.WebService();
ws.Url = "new url";
ws.HelloWorld ();

 

二、动态调用，性能较低

 

 

1. ///<summary>
2.         ///动态Web服务代理方法
3.         ///</summary>
4.         ///<param name="@namespace">传入空间命名</param>
5.         ///<param name="url">传入URL参数</param>
6.         ///<param name="classname">传入类名</param>
7.         ///<param name="methodname">传入方法名</param>
8.         ///<param name="args">传入参数，本参数为顺序参数</param>
