how to create a temporary table in sql to linq query

I want to create a temporary table in linq query. I have searched for the solution but didn't succeeded. here "Node" is temporary table,and "Organization.TblOrganizationUnits" is table in my database. In linq, How can i create a temporary table and how can I perform different joins and union operation of the above query. my sql query is:


string query=string.Format(@"WITH Node (OrganizationUnitId, UnitName,ParentUnitId)                             AS  (                                 SELECT    Organization.TblOrganizationUnits.OrganizationUnitId, Organization.TblOrganizationUnits.UnitName , Organization.TblOrganizationUnits.ParentUnitId                                 FROM       Organization.TblOrganizationUnits                                 WHERE      OrganizationUnitId ={0}                                 UNION ALL                                 SELECT      Organization.TblOrganizationUnits.OrganizationUnitId,  Organization.TblOrganizationUnits.UnitName, Organization.TblOrganizationUnits.ParentUnitId                                 FROM        Organization.TblOrganizationUnits                                 INNER JOIN Node                                 ON          Organization.TblOrganizationUnits.ParentUnitId = Node.OrganizationUnitId                                 )                             SELECT  OrganizationUnitId, UnitName,ParentUnitId FROM   Node                             where  OrganizationUnitId not in (SELECT  ParentUnitId FROM   Node)                            option (maxrecursion 0); ", OrganizationUnitId);
