here start up, role, when add them in array doesn't show value of role, system.int32[]. load xml , transform class code goes here:

        xmldocument doc = new xmldocument();         doc.loadxml("<phrase  role="2"></phrase>         <phrase  role="2"></phrase>         <phrase  role="1"></phrase>         <phrase  role="1"></phrase>         <phrase  role="2"></phrase>         <phrase  role="1"></phrase>         <phrase  role="2"></phrase>");     //get phrases         xmlnodelist phrases = xml.getelementsbytagname("phrase");             foreach (xmlnode phrasenode in phrases)             {                 phrase phrase = nodetophrase(phrasenode);                 phraseslist.add(phrase);             }     //phrase node phrase         private phrase nodetophrase(xmlnode node)         {             phrase phrase = new phrase();             xmlnode rolenode = node.attributes["role"];             if (rolenode != null && !string.isnullorempty(rolenode.value))                 phrase.role = rolenode.value;              return phrase;         }    //crate phrase class public dictionary<string, phrase> phrases = new dictionary<string, phrase>(); public class phrase {     public string role = null; } 

my create array , remove same value code goes here:

//create array         list<int> roleintlist = new list<int>();         foreach(var roles in phrases){             var rolenode = roles.value phrase;             int rolenum = int.parse(rolenode.role);             roleintlist.add(rolenum);//this can't value 2,1,1,2,1,2;;             int [] roleint = roleintlist.distinct().toarray();//this not work;         }    

looking @ code labeled // create array looks may want move line:

 int [] roleint = roleintlist.distinct().toarray(); 

to outside foreach loop:

 list<int> roleintlist = new list<int>();  foreach(var roles in phrases){       var rolenode = roles.value phrase;       int rolenum = int.parse(rolenode.role);       roleintlist.add(rolenum);//this can't value 2,1,1,2,1,2;;  }   int [] roleint = roleintlist.distinct().toarray();//this not work;
