Querying Inventory Items

@operator

Hi,

I want to query the Inventory Item (SKU) from NetSuite based on itemID via Webservices.

I am using search method for which I am creating Itemsearch, ItemsearchBasic and  SerachstringField.  I am using the following code

  ItemSearch   Itemsrch = new ItemSearch();
  ItemSearchBasic  ItemsrchBasic  = new ItemSearchBasic();
  SearchStringField entityId = new SearchStringField();
  entityId = new SearchStringField();
  entityId.@operator = SearchStringFieldOperator.contains;
  entityId.operatorSpecified = true;  
  entityId.operatorSpecified = true;
  entityId.searchValue = "300";
  ItemsrchBasic.itemid  =  entityId ; 
  Itemsrch.basic = ItemsrchBasic ;
  SearchResult response = cnw.search(Itemsrch);

I am not getting itemid for itemrichbasic. Can anyone please suggest me how to get the items based on itemid.

Any help or sample code would be greatly appreciated...
