A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.
If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).
What if I want to obtain a distinct list based on one or more properties?
Simple! You want to group them and pick a winner out of the group.
List<Person> distinctPeople = allPeople
.GroupBy(p => p.PersonId)
.Select(g => g.First())
.ToList();
If you want to define groups on multiple properties, here's how:
List<Person> distinctPeople = allPeople
.GroupBy(p => new {p.PersonId, p.FavoriteColor} )
.Select(g => g.First())
.ToList();
Note: Certain query providers are unable to resolve that each group must have at least one element, and that First is the appropriate method to call in that situation. If you find yourself working with such a query provider, FirstOrDefault may help get your query through the query provider.

This is how you would add a
ListViewItemcreated in code to yourListView:However, I agree with MrTelly that this shouldn't be necessary, you should be setting
ListView.ItemsSourceto some collection rather than manipulatingListView.Itemsdirectly.If you give us more details about what you want to accomplish maybe we can help you do it the WPF way, which is not always the easy way at first, but it's much easier in the long run.
