I want to manipulate all entries in a ListView, preferably in parallel.

```
Parallel.Foreach<ListViewItem>(auftraegeView.Items, line => 
{
    line.Font = new Font(line.Font.FontFamily, someInt);
});

```

That refuses to work though, because

ListViewItemCollection doesn't offer methods like `ToList()` or such.  

I a sort of for-the-laughs-and-giggles-attempt I made a cast

```
(IEnumerable<ListViewItem>)auftraegeView.Items

```

That didn't throw a Compiler-Error, but caused an InvalidCasTException at runtime.

Note:  

The pointy brackets are inversered intentionally so they don't get eaten up as HTML here. 

**Question:**  

Is there a way to convert `ListView.Items` / `ListViewItemCollection` to something that implements the IEnumerable-Interface, hence works with `Parallel.ForEach`?
