Use this method to remove a group from the collection when you have the index of the group within the collection. Note that removing groups from the ListView.Groups collection does not remove items from the System.Windows.Forms.ListView control.

To remove a group using a reference to the object, use the ListViewGroupCollection.Remove(ListViewGroup) method instead. To remove all the groups from the collection, use the ListViewGroupCollection.Clear method. When you remove an item from the collection, the indexes change for subsequent items in the collection. All information about the removed item is deleted.
