[DotNetDevelopment] Accessing all selected items from a listbox

[yogs]

Hi friends,
I am trying to access all selected items' values from a listbox.
I can iterate through the list using following code

Dim listItems As String
 For ii = 0 To size
            listItems = ListBox1.GetItemText(ListBox1.Items(ii))
Next

But unable to access the selected items' values.
Please help me to solve this problem.
