CheckedListBox and list of checked items with their indexes

I have a CheckedListBox like this:

:'''''''''''''''/\
: [ ] item1     ||
: [x] item2     ||
: [ ] item3     ##
: [ ] item4     ||
: [x] item5     ||
L...............\/

Now I want to extract indexes of checked items: 

int[] indexes = ExtractCheckedIndexes (myCheckedListBox);

Now indexes should have 2 elements = { 1, 4 }.
How to achieve this?
