//webServices 應當支撐Get和Post挪用，在web.config應當增長以下代碼

// <protocols>

// <add name="HttpPost"/>
// </protocols>

//挪用示例：
//Hashtable ht = new Hashtable(); //Hashtable 為webservice所須要的參數集
//ht.Add("str", "test");
//ht.Add("b", "true");
//XmlDocument xx = WebSvcCaller.QuerySoapWebService("http://localhost:81/service.asmx", "HelloWorld", ht);
//MessageBox.Show(xx.OuterXml);
