wpf 给listview的数据源转换为集合

目的是点击某个按钮把一条数据从 itemssource中移除

 private void delete_Click_1(object sender, RoutedEventArgs e)

{
DtsInterfaceItemInfo dtsfice= (DtsInterfaceItemInfo)(sender as FrameworkElement).DataContext;   获取点击的那列的按钮获取该列的数据
//(this.listview.ItemsSource as List<DtsInterfaceItemInfo>).Remove(dtsfice);  原
(this.listview.ItemsSource as ObservableCollection<DtsInterfaceItemInfo>).Remove(dtsfice);  改后

}

原来报错，改后正常

ObservableCollection需要引用using System.Collections.ObjectModel;
