C# not recognizing ListBox

I have a ListBox in ASP.NET and when I attempt to call the SelectedItems.Count method, it throws me an error  


" 'System.Web.UI.WebControls.ListBox' does not contain a definition for 'SelectedItems' and no extension method 'SelectedItems' accepting a first argument of type 'System.Web.UI.WebControls.ListBox' could be found (are you missing a using directive or an assembly reference?)"

There is no property 'SelectedItems' for ListBox
But 'SelectedItem' is there for ListBox

The ListBox that I am using contains several selected values.  How would I access this in C# code?

Try this code - You need to loop through the items and check whether it is selected or not
foreach (ListItem item in ListBox1.Items)
        {
            if (item.Selected)
            {
                // This item is selected - do your stuff here
            }
        }
