You are trying to remove items from the same listbox you are running your loop on - this is not allowed in C#. By looking at your code, it appears you are trying to empty your list box. Use the Clear method (on the listbox).

I don't think this'll work. Use this instead :

Lstservices.Items.Remove(o);

use bellow

while (Lstservices.SelectedItems.Count>0)
{
Lstservices.Items.Remove(Lstservices.SelectedItem);
}

All that your code does is to remove an item from the SelectedItems collection of your ListBox (i.e. you are unselecting it), not from the ListBox itself. To remove/delete from the listbox replace

            Lstservices.SelectedItems.Remove(Lstservices.SelectedItem);

with

            Lstservices.Items.Remove(Lstservices.SelectedItem);

but bear in mind that, as someone else has mentioned, C# will complain if you try this whilst iterating over the collection.

With foreach, you are not allowed to alter the collection; you could use a while loop instead.
