entity framework - retrieve Ids created by savechanges -

apologies asking related question yesterday, after sleep i've simplified question.

in example below,i loop through objectquery sourcetable , add rows positions table. after adding new rows , saving changes, primary keys (integer identity column) created.

foreach (var row in sourcetable)         {             var newpos = new positions()                 {                     field1 = row.field,                     field2 = row.field2,                     field3 = row.field3                  };          }      entities.savechanges 

in ef 3.5 possible access list of primary keys added above process? similar can done using output statement in t-sql.

sure - need hang on list of entities you're save, , inspect them after they've been saved:

list<positions> _newitems = new list<positions>();  foreach (var row in sourcetable) {     var newpos = new positions()     {         field1 = row.field,         field2 = row.field2,         field3 = row.field3      };      _newitems.add(newpos);  }  entities.savechanges();  foreach(positions p in _newitems) {     console.writeline("id new item is: {0}", p.id); } 

after items have been saved, field representing int identity field should updated automagically, ef, without doing more. inspect field!
