方 法 一 : 選擇項目，右鍵添加服務引用，輸入服務地址，如圖：
點擊確定跳轉到如下界面：
調用 接口：
ServiceReference1.ImportDataServiceClient sr = new ImportDataServiceClient(); string str= sr.interfaceTest("666"); MessageBox.Show(str);
方 法 二：使用代理類，
代理類WebServiceProxy

調用接口，假如接口名叫interfaceTest，
private void button2_Click(object sender, EventArgs e) { string[] sboxinoutrecs = new string[1]; sboxinoutrecs[0] = "1ww"; string[] sArrBoxInOut = new string[0]; Thread sendThread1 = new Thread(send); sendThread1.Start(sboxinoutrecs); } private static void send(object sboxrecs) { string IP = "10.80.16.38"; string sServerPort = "8081"; string swebsurl = "http://" + IP + ":" + sServerPort + "/phyServer/services/ImportDataService?wsdl"; //wsdl地址 string swebsname = "webServN"; TrhaConst.wsdScab = new WebServiceProxy(swebsurl, swebsname); string[] sboxinoutrecs = (string[])sboxrecs; string sWebsRet = ""; string funname = "interfaceTest"; try { sWebsRet = (string)TrhaConst.wsdScab.ExecuteQuery(funname, sboxinoutrecs); } catch(Exception ex) { MessageBox.Show(ex.Message); return; } }
