@Michhes: using SPList.ItemCount is a good way of getting the number of elements. It doesn’t require a roundtrip to the database as the itemcount is kept in memory. Check out my other blogs on the SharePoint topic – you will find some more useful information about the SharePoint API

I use SPList.ItemCount instead and/or an alternative access method (eg. GetItems() with a CAML query).

The above examples behave the same way in debug or release. Accessing the property is actually invoking the get accessor method. As the get accessor is in fact a method the compiler cannot just optimize the call for you as there can be logic in the accessor that needs to be exected each time the property is accessed.

There is however a better way to iterate through the list – namely – using a foreach loop. Maybe thats what you are refering to.
The foreach loop is compiled in a way that the propertie’s IEnumerator return value is stored in a local variable. This IEnumerator is then used to iteratore over each element.

I wonder if you tested this behavior in Release build mode?
I think that it could work normally, because VS will optimize your calls
