             ServiceTestClient client = new ServiceTestClient();
             double resl1 =  client.Divide(, );
             Console.WriteLine(resl1);
         }
     }

     [WebServiceBinding("Service1Soap", "http://asn.test.cn/")]
     public class ServiceTestClient : SoapHttpClientProtocol
     {
         public ServiceTestClient()

             this.Url = "http://localhost:49559/Service1.asmx";
         }

         [SoapDocumentMethod("http://asn.test.cn/Divide"]
         public double Divide(double x, double y)
