No Duplicates In List With Custom Attribute

Hello people, I would like to create attribute that block add second same object. How can I do this ? Thanks in advance!

At design-time with the inspector or at run-time? Or both?

The first one would require you to have a property drawer that loops through your array/list and removes duplicates.

The second one would be as simple as using an interface to add elements to your list, rather than exposing the list publicly, such as:

public void AddItem(Item item)
{
   if(list.Contains(item) == false)
       list.Add(item);
}
