Sorry for a late reply. I was onto some work.

ListBox1.Items[i].Text would give you the text of the selected Item.
You actually don't need to navigate to each item if you need the selected text or value.
Just use ListBox1.SelectedValue for selected value or ListBox1.Text for selected text.

Put a debugger to see where the code is breaking and whose value is null.

Solution 2

look at this:

ListBox lst = new ListBox();
            lst.Items.Add("item1");
            lst.Items.Add("item2");
            lst.SelectedIndex = 0;
            string item = lst.SelectedValue;
