c# - LINQ? Refactoring foreach -

-

is there better way write this? feel i'm getting rusty c# after doing lot of javascript lately. can improved?

    foreach (var item in this.cartitems)     {         if (item.effectiveprice != null)         {             this.cartitems[this.cartitems.indexof(item)].effectiveprice =                  currencyhelper.getlocalizedcurrency(item.effectiveprice);         }     }

well, could write in linq query syntax from , where, i'm not sure big change; i'd more interested in knowing if lookup unnecessary:

this.cartitems[this.cartitems.indexof(item)].effectiveprice =              currencyhelper.getlocalizedcurrency(item.effectiveprice);

to:

item.effectiveprice = currencyhelper.getlocalizedcurrency(item.effectiveprice);

other that, i'm not sure worth bother of changing it; i'd leave as:

foreach (var item in this.cartitems) {     if (item.effectiveprice != null) {         item.effectiveprice = currencyhelper.getlocalizedcurrency(item.effectiveprice);     } }
