C# 在你的 winforms 中嵌入 youtube/videos

Question

我有问题，我在 winform 中添加了 Shockwave 播放器。不过youtube好像不支持了。那么如何将 video/youtube 视频嵌入到我的 winform 应用程序中呢？

Answer 1

您可以使用 WebBrowser 控件来显示嵌入的 YouTube 视频。为此，将 WebBrowser 控件放在窗体上并将以下代码放在窗体中：

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    var embed = "<html><head>"+
    "<meta http-equiv=\"X-UA-Compatible\" content=\"IE=Edge\"/>"+
    "</head><body>" +
    "<iframe width=\"300\" src=\"{0}\"" +
    "frameborder = \"0\" allow = \"autoplay; encrypted-media\" allowfullscreen></iframe>" +
    "</body></html>";
    var url = "https://www.youtube.com/embed/L6ZgzJKfERM";
    this.webBrowser1.DocumentText = string.Format(embed, url);
}

备注

您应该确保使用正确的 url。例如，对于您可以在此地址看到的视频：https://www.youtube.com/watch?v=L6ZgzJKfERM，嵌入 url 是 https://www.youtube.com/embed/L6ZgzJKfERM.
此外，您还应确保允许以嵌入式方式播放视频。有些视频只允许在 youtube 上播放，但在您点击播放按钮后，您会收到此错误消息：

This video contains content from XXXXXX. It is restricted from playback on certain sites or applications.

        cn.Open();
        Response.Write("check "+cn.State);                      
        String link = "<iframe width=\"300\" height = \"200\" src = \"https://www.youtube.com/embed/" + TextBox1.Text + "\" frameborder = \"0\" allow = \"autoplay; encrypted-media\" allowfullscreen></iframe>";
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "INSERT INTO Video(VIDEO_DETAILS,PATH)VALUES('"+"YOUTUBE" +"','" + link +"')"; 
        cmd.Connection = cn;
        cmd.ExecuteNonQuery();
        TextBox1.Text = "";
        cn.Close();
      }
