salesforce - pass list<string> as parameter to webservice -

please help!!

what correct way send list of string parameter webservice ?

list < sobject > objectcontents; // {get; set;} contains records of selected object list str3 = new list (); string formattedvalue;

 (sobject :  (sobject : objectcontents)) // (sobject : objectcontents)  {  for(string field:fieldapis){  //  fieldapis contains list of fieldnames             formattedvalue = '\'' + a.get(field) + '\'' ;  //fetches value of each field   }    str3.add(formattedvalue );    }      //sending data webservice sqlarray19.arrayofstring a= new sqlarray19.arrayofstring();   sqlserverconnector9.basichttpbinding_iservice1 stub = new sqlserverconnector9.basichttpbinding_iservice1();    

//sqlarray19 , sqlserverconnector9 classes formed while importing wsdl salesforce

list<string> insertmsg = stub.insertquery(str3); // getting error in line   "compile error: method not exist or incorrect signature: [sqlserverconnector9.basichttpbinding_iservice1].insertquery(list<string>)" 

.net webservice fetch values salesforce , return values

 public list<string> insertquery(list<string> values)     {         return values ;     } 

collections can troublesome data types when working across platforms web services. try converting list string[] (and changing method, of course).
