c#: how to reference the tag property of a listviewitem

sorry for the noob question, but I added a tag property to a ListViewItem to act as a valuemember. But now how do i reference it? Im trying to recall that tag on a double click event of the listitem at runtime. I was hoping it would be something like this (stub)

MessageBox.Show(lsvItems.SelectedIt开发者_StackOverflowem.Tag);

how do i get at this?

Make sure there is at least one item selected and then you can do

 MessageBox.Show(lstView.SelectedItems[0].Tag.ToString());

If you have a defined entity (for eg. Person instance) added to Tag then you could do

Person p = (Person) lstView.SelectedItems[0].Tag

and access the instance's properties

MessageBox.Show(p.Name);

Assuming one item is selected:

 MessageBox.Show(listView1.SelectedItems[0].Tag.ToString());
