ComponnetOne Silverlight 和 WPF 平台提供了视频播放控件 C1MediaPlayer。可以在应用中添加视频播放功能，增强应用的可交互性。本篇文章是一篇基础应用文章-将阐述如何使用 C1MediaPlayer 播放视频文件。对于刚刚接触ComponnentOne控件套包的用户将有所帮助。下面分步讲解使用方法：
1.在 XMAL 页面添加 C1MediaPlayer 控件。
1: <c1:C1MediaPlayer Height="800" VerticalAlignment="Top" Name="c1mediaplayer"/>
2.添加 Button 并且调用 Click 事件调用 OpenFileDialog 选择文件：
1: <Button Width="70" Height="20" Content="选择文件" VerticalAlignment="Bottom" Click="Button_Click"/>
3.Button Click 事件中选择文件代码如下：
1: private void Button_Click(object sender, RoutedEventArgs e)
2: {
3: OpenFileDialog op = new OpenFileDialog()
4: {
5: Filter = "Video files(*.wmv)|*.wmv|All Files(*.*)|*.*"
6: };
7:
8: if (op.ShowDialog()==true)
9: {
10: //读取视频文件流
11: FileStream stream = op.File.OpenRead();
12:
13: //添加视频项
14: C1MediaItem plI = new C1MediaItem();
15: plI.MediaStream = stream;
16: c1mediaplayer.Items.Add(plI);
17:
18: //自动播放视频
19: c1mediaplayer.Play();
20: }
21: }
效果图：
