//webServices 应该支持Get和Post调用，在web.config应该增加以下代码

//
//
//
//调用示例：
//Hashtable ht = new Hashtable(); //Hashtable 为webservice所需要的参数集
//ht.Add("str", "test");
//ht.Add("b", "true");
//XmlDocument xx = WebSvcCaller.QuerySoapWebService("http://localhost:81/service.asmx", "HelloWorld", ht);
//MessageBox.Show(xx.OuterXml);
