c# - webservice calculate sum in console app? -

not sure if able understand here code:

        case 1:         double[] myarrai1 = new double[3];         console.foregroundcolor = consolecolor.yellow;         console.backgroundcolor = consolecolor.darkgray;         console.writeline("*-------------------------------------------------------* ");         console.writeline("*  enter array of numbers sum total       * ");         console.writeline("*-------------------------------------------------------* ");         console.writeline("insert number");         myarrai1[0] = double.parse(console.readline());         console.writeline("insert number");         myarrai1[1] = double.parse(console.readline());         console.writeline("insert number");         myarrai1[2] = double.parse(console.readline());         drawstarline();         foreach (double d in myarrai1)         console.writeline( d );         webservices09004961.servicereference1.calculatesumrequest array = new servicereference1.calculatesumrequest();         //servicereference1.calculatesumrequest array = new servicereference1.calculatesumrequest();         webservices09004961.servicereference1.arrayofdouble arrayofdoubles = new webservices09004961.servicereference1.arrayofdouble();          //calculatesumoflist.servicereference1.service1soapclient client = new calculatesumoflist.servicereference1.service1soapclient();         //calculatesumoflist.servicereference1.arrayofdouble arrayofdoubles = new calculatesumoflist.servicereference1.arrayofdouble();         arrayofdoubles.addrange(myarrai1);         double e = array.calculatesum(arrayofdoubles); //error on line calculatesum?         console.writeline("=" + e);         console.readline();         break; 

i store 3 user input numbers in myarrai1 "sum" sum have made webreference calculatesumoflist.

but says webreference not contain calculatesum in webservice, yet , im using in windows forms within same build/project?

thanks.

so trial , error had realised calling client first time round used webservice.

    case 1:         double[] myarrai1 = new double[3];         console.foregroundcolor = consolecolor.yellow;         console.backgroundcolor = consolecolor.darkgray;         console.writeline("*-------------------------------------------------------* ");         console.writeline("*  enter array of numbers sum total       * ");         console.writeline("*-------------------------------------------------------* ");         console.writeline("insert number");         myarrai1[0] = double.parse(console.readline());         console.writeline("insert number");         myarrai1[1] = double.parse(console.readline());         console.writeline("insert number");         myarrai1[2] = double.parse(console.readline());         drawstarline();         foreach (double d in myarrai1)         console.writeline( d );         webservices09004961.servicereference1.service1soapclient client2 = new servicereference1.service1soapclient();         webservices09004961.servicereference1.arrayofdouble arrayofdoubles = new webservices09004961.servicereference1.arrayofdouble();          arrayofdoubles.addrange(myarrai1);         string e = client2.calculatesum(arrayofdoubles);         console.writeline("=" + e);         console.readline();         break; 

so sum (no pun intended) have spent 5 hours watching , reading tutorials or used abit of trial , error of so!
