在不使用媒体播放器的情况下播放视频[Winform] [英] Play video without using media player [Winform]

问题描述

我想像那个家伙那样播放视频 [link ] .

I want to play a video like that guy did [link].

我正在使用C#Windows Form Application(不是NXA). 但是我不知道如何. 我尝试使用Microsoft.DirectX.AudioVideoPlayback，但没有运气.

I'm working on C# Windows Form Application (not NXA). But I don't know how. I tried using Microsoft.DirectX.AudioVideoPlayback but no luck.

这是我到目前为止尝试过的:

This is what I tried so far :

OpenFileDialog rihanna = new OpenFileDialog();
if(rihanna.ShowDialog() == DialogResult.OK)
{
    video = new Video(rihanna.FileName);
    video.Owner = panel1;    
    video.Stop();    
}

现在我该怎么办?我尝试使用视频课，但正如我所说，这是行不通的. 我可以编译，但是在运行程序时，看不到窗体窗口.

Now what can i do? I tried using video class but as I said it just did not work. I'm able to compile but when I'm running the program, I don't see the form window.
