c# - What is the most efficient way of getting these XML nodes and then saving them to the web service? -

-

i know simplistic, haven't worked xml files yet. proper way go getting necessary xml nodes , saving them wsdl? please let me know if there's way can make more efficient/cleaner or easier.

code gets nodes xml document , puts them dictionary:

public filereference loadxmldoc(string strfile) {     logger.log("loadxmldoc:" + strfile);      filereference fileref = new filereference();     fileref.filename = strfile;      //create xml document obj     xmldocument inputxmldoc = new xmldocument();     fileref.isvalid = false;     //load xml document     #region     try     {         inputxmldoc.xmlresolver = null;         inputxmldoc.load(strfile);//load xml file         string input = inputxmldoc.outerxml;//get string          console.writeline("success,loaded xml");         logger.log("loaded xml:" + strfile);          //xmlnodelist xlist = inputxmldoc.getelementsbytagname("nulogyfile");         //logger.log("got xlist, length = " + xlist.count);          fileref.importlist = new dictionary<string, xmlnode>();          nodenames = new list<string>{ "orderid", "customerid", "customername" };          try         {             int = 0;             foreach (string name in nodenames)             {                 console.writeline("adding xml node " + name);                  if (inputxmldoc.getelementsbytagname(name) != null)                 {                     xmlnodelist xlist = inputxmldoc.getelementsbytagname(name);                     foreach (xmlnode node in xlist)                     {                         fileref.importlist.add(name, node); //add individual node within nodelist                     }                 } //add specified node xml doc                 else                 {                     nodenames.removeat(i);                 }                 i++;             }           }         catch (exception ex)         {         }     }     catch (exception ex)     {     } }

code saving new invoice (gets dictionary info):

invoices.invoiceorder newinvoice = new invoices.invoiceorder();  if (fileref.importlist.containskey("orderid")) {newinvoice.orderid = convert.toint32(fileref.importlist["orderid"].innertext);} if (fileref.importlist.containskey("customername")) {newinvoice.customername = fileref.importlist["customername"].innertext;} if (fileref.importlist.containskey("customerid")) { newinvoice.customerid = convert.toint32(fileref.importlist["customerid"].innertext); }  //save new invoices _service.saveinvoices(new[] { newinvoice });
