我有一个comboBox，然后一个MediaElement.....然后就是想通过下拉列表框选择，可以在播放不同的视屏。。   me.Source = new Uri(ListData[i].mvUrl.ToString());但是到这里就有问题了，一直说URI格式不对。。。求高手解答。。。

我的代码： List<move> ListData = new List<move>();
        public MainPage()
        {
            InitializeComponent();
           
            ListData.Add(new move { mvUrl = "/SilverlightApplication1;component/media/01.wmv", note = "笑话" });
            ListData.Add(new move { mvUrl = "/SilverlightApplication1;component/media/kobe.wmv", note = "篮球比赛" });
      
            cbMovie.DataContext = ListData;
            cbMovie.SelectedIndex = 0;
        }
        public class move
        {
            public string mvUrl { get; set; }
            public string note { get; set; }
        }

 private void cbMovie_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            int i = cbMovie.SelectedIndex;
            me.AutoPlay = true;
            me.Source = new Uri(ListData[i].mvUrl.ToString());
            me.Play();
