c# - Handle application error problems -

-

i using mvc project , hase been logging application errors in global.ascx.

this code 

protected void application_error(object sender, system.eventargs e)         {             system.web.httpcontext context = httpcontext.current;             system.exception exception = context.server.getlasterror();             var stacktraceexcep = new stacktrace(exception, true); // create stack trace             var stacktrace = stacktraceexcep.getframes()         // frames                           .select(frame => new                           {                   // info                               filename = frame.getfilename(),                               linenumber = frame.getfilelinenumber(),                               columnnumber = frame.getfilecolumnnumber(),                               method = frame.getmethod(),                               class = frame.getmethod().declaringtype,                           }).firstordefault();               string filename = stacktrace.filename;             string linenumber = stacktrace.linenumber.tostring();             string columnnumber = stacktrace.columnnumber.tostring();             string methodname = stacktrace.method.name;             string classname = stacktrace.class.name;             int errornumber = convert.toint32(errorrepository.adderror(exception.message, filename, convert.toint32(linenumber), convert.toint32(columnnumber), methodname, classname));//this line helps stores error in database.             response.redirect(string.format("~/error/{0}/?errornumber={1}", "app_error", server.urlencode(errornumber.tostring())));//pass error number cantroller show error number(last inserted id) in view             context.server.clearerror();         }

okay let me go problem here

the above code working fine on local computer . code stores (error path , error name ,error line number ,error column number, error method name, error class name .) in database.

now, when publish project , deploy publish version on server (arvixe) .

the code in application error method works fine class name method name , exception message , stores data in database, error line number , error column number not stored in database. saw database , it's stores nothing .

what problem ? why error line number , error column name not stored when deployed web server(everything works fine on local system) ?

i have doubts

1) project published version , project files(class,controllers,models,etc ( think know that)) converted dll , guess stacktrace not error line details ? correct ? else tell me .

2)the server not have visual studio . guess not working ? correct else tell me ?

it seems connection string not set properly. handle application error happens when there's no way connect database. open web.config file , add connection string there.
