WPF的ListView中怎么获得所选中的行的信息？？

Question

ListView的最后一行是超链接，“详细” 怎么在跳转页面时，获取某行的主键呢？？？

Answer 1

int 选择的行数=listbox.item.selected;

Answer 2

/// <summary>
        /// 获取查看或删除的项
        /// </summary>
        /// <returns></returns>
        public object GetItem(ListView listView)
        {
            try
            {
                object item = null;                HitTestResult result = VisualTreeHelper.HitTest(listView, Mouse.GetPosition(listView));
                object context = (result.VisualHit as FrameworkElement).DataContext;
                if ((context is object[]) == false)
                    item = context;
                return item;
            }
            catch
            {
                throw;
            }
        }
再通过 DataRowView objDRV = quickBLL.GetItem(this.ltv_Bill) as DataRowView;
