webServices 应该支持Get和Post调用，在web.config应该增加以下代码
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
1 #region Tip:使用說明
2 //webServices 應(yīng)該支持Get和Post調(diào)用，在web.config應(yīng)該增加以下代碼
3 //<webServices>
4 // <protocols>
5 // <add name="HttpGet"/>
6 // <add name="HttpPost"/>
7 // </protocols>
8 //</webServices>
9
10 //調(diào)用示例：
11 //Hashtable ht = new Hashtable(); //Hashtable 為webservice所需要的參數(shù)集
12 //ht.Add("str", "test");
13 //ht.Add("b", "true");
14 //XmlDocument xx = WebSvcCaller.QuerySoapWebService("http://localhost:81/service.asmx", "HelloWorld", ht);
15 //MessageBox.Show(xx.OuterXml);
