我有vb.net代码使用捕获卡捕获视频并以一种工作正常的形式显示它。现在我需要将vb.net代码转换为C＃代码，而我这样做我得到上面定义的错误。无法使其工作。任何让它运作的想法都会非常感激。这是代码：

//Call to AddCam to select an available camera

修复以下代码：
private System.Windows.Forms.Button withEventsField_cmdFrame;
// internal System.Windows.Forms.Button cmdFrame
{
get { return withEventsField_cmdFrame; }
set
