Vlc.DotNet.Forms.VlcControl cc = new  Vlc.DotNet.Forms.VlcControl();
            cc.Width = 500;
            cc.Height = 400;
            cc.Top = 100;
            cc.Left = 100;

            Vlc.DotNet.Core.Medias.MediaBase media = new Vlc.DotNet.Core.Medias.LocationMedia("dshow:// ");
            media.AddOption(":dshow-size=1600*1200");
            media.AddOption(":dshow-vdev=USB CAM2");

            cc.Play(media);
            this.Controls.Add(cc);
            cc.BringToFront();



            //cc.TakeSnapshot("D:\\111.jpg", 1600, 1200);//截圖

　註意

Vlc.DotNet.Core.Medias.MediaBase media = new Vlc.DotNet.Core.Medias.LocationMedia("dshow:// ");
初始化MediaBase 時只需

"dshow:// "
即可

選擇哪個相機需要AddOption

，選擇分辨率之類的參數也要AddOption

但不支持相機index，必須相機name，可以參考使用AForge.NET Framework打開攝像頭 C#獲取對應index的name

使用Vlc.DotNet打開攝像頭並截圖 C#
