c# - Add custom culture to web service? -

i have web service on server won't able manage regional settings. web methods need date format "d.m.yyyy", when make call web method , pass date-time string, server should parse string date format "d.m.yyyy" only, date separator "." in desktop application doing following code:

 public partial class mainf : form  {    cultureinfo customculture = new cultureinfo(cultureinfo.currentculture.name);        public mainf()       {            initializecomponent();             customculture.datetimeformat.shortdatepattern = "d.m.yyyy";            customculture.datetimeformat.dateseparator = ".";            thread.currentthread.currentculture = customculture;       }       private void displaydate(string date)       {         string output="";         datetime mydate;         if (!datetime.tryparse(input, customculture, datetimestyles.none, out mydate))         {            messagebox.show("date cannot parsed!");         }         else         {            messagebox.show(mydate.toshortdatestring());         }       }  } 

but in webservice should put definition date format,date separator , current thread culture = custom culture??? in every single method or not? sorry not familiar web services now. thank in advance!

if wanna supply custom format, need use datetime.tryparseexact method instead of datetime.tryparse. example;

if(datetime.tryparseexact(input, customculture.datetimeformat.shortdatepattern,                            customculture, datetimestyles.none, out mydate)) {     messagebox.show("date cannot parsed!"); } 

exact difference between these 2 methods points custom format.

by way, don't see any input in code variable maybe might mixing date or output variables..
