Solution 1

I am not sure why you think this will work. Why not use foreach to iterate over the items ? Items.ToString() is obviously not using your index. Try Items[i].Text, that would mean you were not checking the same thing over and over, but instead checking each individual item.

Also, why use 'c' instead of a bool ?

Solution 2

It all makes no sense, plus a couple of bugs:

You make one iteration more that the number of items; use < instead of <= in the loop ending condition.

Also, cmbdep.Items.ToString() will not return what you expect. You probably wanted an item by index, so use cmbdep.Items[i].ToString().

The calculation if c makes no sense. Do you simply want check up if the text is one of the items? (You don't have to answer. :-))
