i want delete node <reference include="system.data" />

from csproj file programmatically. csproj file file structure :

<itemgroup>     <reference include="microsoft.csharp" />     <reference include="system.data.oracleclient" />     <reference include="system.messaging" />     <reference include="system.web.dynamicdata" />     <reference include="system.web.entity" />     <reference include="system.web.applicationservices" />     <reference include="system.componentmodel.dataannotations" />     <reference include="system" />     <reference include="system.data" />     <reference include="system.core" />     <reference include="system.data.datasetextensions" />     <reference include="system.web.extensions" />     <reference include="system.xml.linq" />     <reference include="system.drawing" />     <reference include="system.web" />     <reference include="system.xml" />     <reference include="system.configuration" />     <reference include="system.web.services" />     <reference include="system.enterpriseservices" />   </itemgroup>

xmldocument doc = new xmldocument(); doc.load(fullfilepath); xmlnode node = doc.selectsinglenode(@"/project/itemgroup/reference[@include='system.data']");  node.parentnode.removechild(node);  doc.save(fullfilepath);
