Getting Selected Items From WinForm ListBox?

Easy, depending on what type you stored:

foreach (MyItemType item in listBox1.SelectedItems)
{
   ...
}

Because this is an older, non-generic collection it is better not to use var to declare the item variable. That would only get you a reference of type object.

You can also use other properties like:

if (listBox1.SelectedItems.Count > 0)
   ...
