我想播放像那样的人做的视频 [link]。在不使用媒体播放器的情况下播放视频[Winform]
我正在处理C＃Windows窗体应用程序（而不是NXA）。 但我不知道如何。 我试过使用Microsoft.DirectX.AudioVideoPlayback，但没有运气。
这是我试过到目前为止：
OpenFileDialog rihanna = new OpenFileDialog();
if(rihanna.ShowDialog() == DialogResult.OK)
{
video = new Video(rihanna.FileName);
video.Owner = panel1;
video.Stop();
}
现在我能做些什么？我尝试过使用视频课，但正如我所说，它只是没有工作。 我可以编译，但是当我运行程序时，我没有看到窗体窗口。
欧凯命名空间是显而易见的：
using Microsoft.DirectX.AudioVideoPlayback;
表格一些全局变量：
Video vdo;
public string mode="play";
public string PlayingPosition, Duration;
现在在你的按钮或什么别的打开：
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.ShowDialog();
openFileDialog1.Title = "Select video file..";
openFileDialog1.InitialDirectory = Application.StartupPath;
openFileDialog1.DefaultExt = ".avi";
openFileDialog.Filter = "Media Files|*.mpg;*.avi;*.wma;*.mov;*.wav;*.mp2;*.mp3|All Files|*.*";
vdo = new Video(openFileDialog.FileName);
vdo.Owner = panel1;
panel1.Width = 700;
panel1.Height = 390;
Duration = CalculateTime(vdo.Duration);
PlayingPosition = "0:00:00";
txtStatus.Text = PlayingPosition + "/" + Duration;
vdoTrackBar.Minimum = 0;
vdoTrackBar.Maximum = Convert.ToInt32(vdo.Duration);
而且在一些其他按钮代码开始/暂停：
if (vdo.Playing)
{
vdo.Pause();
btnPlay.Text= "Play";
}
else
{
vdo.Play();
btnPlay.Text= "Pause";
}
BTW： 不要将其命名变量/成员或一些女孩后别人在你的代码......
如果不知道如何将它命名，这里有一些Guidelines。
的目标是提供一套统一的命名约定 导致那名让立即感觉到 开发商。

从哪里获得'Microsoft.DirectX'？ –
Microsoft.DirectX与XNA一起是一个不错的选择。如果我没有弄错，最后一个支持它的Visual Studio是2010 – YoniXw
对于AudioVideoPlayback工作，你需要添加AudioVideoPlayback参考，参考>添加引用>浏览> C：> Windows>系统Microsoft.Net>的DirectX托管代码> 1.0.2902.0> Microsoft.DirectX.AudioVideoPlayback.dll
她没有使用变量名称后，女孩，她正在播放视频，并可能有一个恒定的文件与视频的路径，常数被命名为“rihanna.FileName”，所以我想这个是说这是Rihana的视频（如果你不知道，Rihana是一位歌手，所以这可能是一个视频剪辑或什么）。 –
