ODATA Consume Service Operation from C# ASP.NET 4.0 -

i connecting odata service via c# asp.net application, has service operations such as:

getitems(int? itemid, double? price) 

i can consume without issues in browser, e.g.

http://api.mycompany.com/companycatalogue/getitems?itemid=4 

i understand how use linq entities consume odata service, can't find decent explanation of how consume service operations 1 above in c#. have made web reference service in visual studio solution.

so far, have usual consuming of data:

using companycatalogue; //my web reference ... protected void page_load(object sender, eventargs e) {     companycatalogueentities datacontext = new companycatalogueentities (new uri("http://api.mycompany.com/companycatalogue/"));     var result = in datacontext.items select i;  //just example      //this problems     var operationresults = companycatalogue.getitems(6, 20.5); //i made } 

any pointers?

ok, got answer:

using companycatalogue; //my web reference ... protected void page_load(object sender, eventargs e) {     companycatalogueentities datacontext = new companycatalogueentities();       dataservicequery<getitemsresult> q = datacontext.createquery<getitemsresult>("getitems")         .addqueryoption("paramname", 6)         .addqueryoption("paramname2", 20.5);      list<getitemsresult> items = q.execute().tolist(); }
