c# - Deserialize list set index to object property -

i have following xml

<itemsroot>      <itemlist>          <item>              <name>a</name>              <itemlist>                  <item>                     <name>aa</name>                  </item>                  <item>                     <name>ab</name>                  </item>              </itemlist>          </item>          <item>              <name>b</name>          </item>          <item>              <name>c</name>          </item>      </itemlist> </itemsroot> 

my classes are

public class item  {    [xmlignore()]    public int itemindex {get;set;}     public string name {get;set;}     private item[] itemslist;    [xmlelement(isnullable = true)]    [xmlarrayitem("item", typeof(item))]    [xmlarray("itemlist")]    public item[] itemslist    {                 {             return itemslist;         }         set         {             itemslist= value;         }    }  }  [xmlroot("itemsroot")] public class itemsroot {      private item[] itemslist;      [xmlarrayitem("item", typeof(item))]      [xmlarray("itemlist")]      public item[] itemslist      {                 {             return itemslist;         }         set         {             itemslist= value;         }      } } 

code deserializing:

public static object xmldeserialize(string dataxml, type objecttype) {     xmldocument xdoc = new xmldocument();     xdoc.loadxml(dataxml);     xmlnodereader xnodereader = new xmlnodereader(xdoc.documentelement);     xmlserializer xmlserializer = new xmlserializer(objecttype);     var objectdata = xmlserializer.deserialize(xnodereader);      return objectdata; } 

so im trying when deserialize xml wanted populate itemindex variable index of object in list.

i.e.

item object name index 0
item object name b index 1 etc

and

item aa index 0 again
item ab index 1
etc

i not concerned when itemindex populated. can happen after deserialization, figured spot doing this.

here pseudo code of how would've done this.

here read xml file disk.

public static ienumerable<xelement> streamxmldoc(stream inputstream, string nodename) {     using (var reader = new streamreader(inputstream))     {         using (var xmlreader = xmlreader.create(reader))         {             xmlreader.movetocontent();              while (xmlreader.read())             {                 switch (xmlreader.nodetype)                 {                     case xmlnodetype.element:                         if (xmlreader.name == nodename)                         {                             var xelement = xelement.readfrom(xmlreader) xelement;                              if (xelement != null)                             {                                 yield return xelement;                             }                         }                         break;                 }              }         }     } } 

and then, when call streamxmldoc method, can populate model necessary, example below shows.

var counter = 0;     var serializedobjects = xmlhelper.streamxmldoc(fs, nodename);      foreach (var element in serializedobjects)     {         // convert (deserialize) patient xelement instance of despatientmodel class.         var item = xmlhelper.xmldeserialize(element.tostring(), typeof(yourtype));         item.itemindex = counter++;     }
