How do i extract data out from Ienumerable? : I'm coding in C#. I have this code that tells me the difference in my 2 listview data. 

`var diff = ListViewDatabase.Items.Cast<ListViewItem>().Select(x => x.SubItems[1].Text).Except(LstView.Items.Cast<ListViewItem>().Select(x => x.SubItems[1].Text));
MessageBox.Show(string.Format("{0} Missing.", string.Join(",", diff), "\n"));`

Now how do I extract the information out from variable diff to a single string? It needs to be seperated to different string.
