The foreach can iterate only on collections! The i variable in this case may be a list like this:

 List<ProductionOrderItem> i = new List<ProductionOrderItem>();

Now you can iterate on it. The foreach iterate through the list:

 foreach( ProductionOrderItem item in i)
        {
              if(item.data type is string)
              {
                  item.value = "" ;
              }
              if ((item.data type is int)
              {
                item.value = 0 ;
              }

              if (item.data type is stringDateTime))
              {
                  item.value = 2011-01-01 00:00:00;
              }
           else
               // do any thing. 

        }

But remember: don't change the variable i within the loop.
