Following suit from the suggestions here, I added an extension method to return a list of the selected items using LINQ for any type that Inherits from [<code>System.Web.UI.WebControls.<b>ListControl</b></code>][ListControl]. 

Every `ListControl` object has an [`Items`][ListControl.Items] property of type [`ListItemCollection`][ListItemCollection].  `ListItemCollection` exposes a collection of [`ListItems`][ListItems], each of which have a `Selected` property.

###C Sharp:



    public static IEnumerable<ListItem> GetSelectedItems(this ListControl checkBoxList)
    {
        return from ListItem li in checkBoxList.Items where li.Selected select li;
    }

###Visual Basic:



    <Extension()> _
    Public Function GetSelectedItems(ByVal checkBoxList As ListControl) As IEnumerable(Of ListItem)
        Return From li As ListItem In checkBoxList.Items Where li.Selected
    End Function

Then, just use like this in either language:

    myCheckBoxList.GetSelectedItems()

[ListControl]: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listcontrol(v=vs.110).aspx
[ListControl.Items]: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listcontrol.items(v=vs.110).aspx
[ListItemCollection]: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listitemcollection(v=vs.110).aspx
[ListItems]: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listitem(v=vs.110).aspx

I have a CheckBoxList like this:



    <asp:CheckBoxList ID="CBLGold" runat="server" CssClass="cbl">
        <asp:ListItem Value="TGJU"> TG </asp:ListItem>
        <asp:ListItem Value="GOLDOZ"> Gold </asp:ListItem>
        <asp:ListItem Value="SILVEROZ"> Silver </asp:ListItem>
        <asp:ListItem Value="NERKH"> NE </asp:ListItem>
        <asp:ListItem Value="TALA"> Tala </asp:ListItem>
        <asp:ListItem Value="YARAN"> Sekeh </asp:ListItem>
    </asp:CheckBoxList>

Now I want to get the value of the selected items from this CheckBoxList using foreach, and put the values into a list.
