Convert non-generic type to generic type in c#

Just today when mussing with List controls and their SelectedItems property came to a point where I needed to convert their SelectedItems property to a generic list (because god knows why it is non-generic).

I needed this because I wanted to query over the selected items and LINQ doesn’t work with non-generic lists so…

Turns out the solution is quite simple:

IEnumerable<string> genericizedItems = itemsListBox.SelectedItems.OfType<string>();

Works like a charm, hope this helps!

Cheers!
