c# - update generic entity in linq to object -

i have function written in linq sql

public static bool update(system.linq.expressions.expression<func<t,bool>> predicate,action<t> setter)         {             try             {                 context mycontext = new context ();                 t updateobject;                 updateobject = mycontext.gettable<t>().where(predicate).first();                 setter(updateobject);                 nhagodb.submitchanges();                 return true;             }             catch (exception ex)             {                 return false;             }         } 

but dont know how write in linq object, there's no method gettable<t>().where(predicate).first();

please many :)

i don't see such method necessary in linq objects. code can work itself. e.g.

var myobject = mylist.first(x => x.something); myobject.updatesomething(newvalue); // or just: mylist.first(x => x.something).updatesomething(newvalue); 

if did want method this, called like:

mylist.update(x => x.something, x => x.updatesomething(newvalue)); 

the former shorter, clearer (imo), , faster latter.
