Getting index for multiple selected item in ListBox in c#

Question

I have two ListBoxes. First ListBox items are list of "Products". and second ListBox items are list of "Item in Product" so When user click the item in first(Product) Listbox The second ListBox will show the list of items in selected Products.

eg:

Products     Items in Proucts
  AA*                 1
  BB                  2
  CC                  3

in example above current user selected AA products. And 1,2,3 are the items in product AA.

For the current program,i've done. User only can select One "Products" at a time. Then i want to change to multipleselected. So i want to get index number for each product that user selects, then i can retrieve data from database to get "Items In Products" for all selected products.

if (productsListBox.SelectedItmes.Count >= 0)
{
 // please provide me coding here to get index number for each selected items in   productListBox.
}

SelectedIndices should be replaced by SelectedItems. Tried to suggest an edit, but the reviewer answered "This edit is incorrect". Go figure why.

if (productsListBox.SelectedItmes.Count >= 0)
{

    string IDs = string.Empty;
    foreach( ListItem li in productsListBox.SelectedItmes ) 
    {
        IDs += li.Value+"," ;
    }
        IDs = IDs.Trim(',');

}

It'll give you a CSV of selected IDs

Ok. Actually you didn't mentioned web or windows here, I thought you were asking about web (asp.net).

Tried to edit for typos, but got rejected when I renamed SelectedItmes to SelectedItems.

private string GetTagsList()
    {
        string Tags = string.Empty;

        if (lstTags.SelectedItems.Count >= 0)
        {
            for (int i = 0; i < lstTags.SelectedItems.Count; i++)
            {
                Tags += lstTags.SelectedIndices[i].ToString() + ",";
            }
            Tags = Tags.Trim(',');
        }

        return Tags;
    }
