1、使用:在aspx页面中动态调用Webservices
经过测试，在winform中也可以调用成功
2、调用:
//webservices地址,示例:http://localhost:1008/ws/DataUpdateService.asmx
private static string ServiceUrl = ConfigurationManager.AppSettings["DataUpdateService"];
//参数以数组形式按顺序传递，不用写参数名
string[] args = new string[] { sOrgNo };
//调用服务方法，获取数据
string sResult = WSHelper.InvokeWebService(ServiceUrl, "GetTeacherCourseList", args) as string;//Web服务地址，服务方法，参数
3、实例代码
