modify list value with foreach iteration variable

[Bob]

Hi,
I have a list of widgets.
I want to iterate through the selected items collection and modify one of
the widgets properties.
I tried
foreach(widget w in lst.SelectedIte ms)
w.MyProperty = something;
but I get a message saying "Cannot modify members of w because it is a
foreach iteration variable"
What is the point of iteration if you can't modify the objects?
Thanks
Bob

What is widget? What is lst? What is MyProperty?

You can modify the objects. You can't modify the collection, though. If
modifying the object would cause it to modify the collection, then that
isn't allowed.

I think your complaint would be more meaningful if it was precise!

Hi Barry,
Thanks for your reply.
Problem solved. My mistake was assuming that a listbox items collection
could have it members modified.

Bob
