c# - Searching Country by Country code -

i working on search method, called ajax, , updates webgrid in mvc4. search go through list of project objects, contains fields.

one of fields country. , right code checks if input string contains search string:

private bool stringstartwith(string input, string searchstring) {      bool startwith = false;     var inputlist = new list<string>(input.tolower().split(' ').distinct());     var searchlist = new list<string>(searchstring.tolower().split(' '));      var count = (from inp in inputlist sear in searchlist inp.startswith(sear) select inp).count();     if (count == searchlist.count)         startwith = true;     return startwith; } 

but want able search country code. if write "dk", should tell equal denmark.

i hope can it. thanks.

        private bool inputstartwithsearch(string input, string searchstring)     {         if(searchstring[searchstring.length-1].equals(' '))             searchstring = searchstring.substring(0,searchstring.length-2);          bool startwith = false;         var inputlist = new list<string>(input.tolower().split(' ').distinct());         var searchlist = new list<string>(searchstring.tolower().split(' '));          if (searchstring.length == 2)         {             var countrycode = new regioninfo(searchstring.toupper()).englishname;             if (inputlist.any(country => country.tolower().equals(countrycode.tolower())))             {                 return true;             }         }         var count = (from inp in inputlist sear in searchlist inp.startswith(sear) select inp).count();         if (count == searchlist.count)             startwith = true;         return startwith;     } 

thanks lot.

may can use regioninfo:

// returns bulgaria new regioninfo("bg").englishname;
