 ICollectionView：可以将List中的改变的内容更新到ＵＩ上面，很好用！

                ICollectionView dataView = CollectionViewSource.GetDefaultView(CompetitionTable.ItemsSource);
                if (dataView != null)
                {
                    dataView.Refresh();
                }
具体见ｓａｍｐｌｅ

［读出文件中的比赛的人员名字显示在ＵＩ上面，然后进行７轮比赛，每次都将比分重新排序，然后显示出来，得分随机给出，每轮的比赛人员按照得分高低依次得出］
