推荐答案

尝试一下 http://www.developerfusion.com/tools/convert/vb-to-csharp/ [ ^ ]

我在引发事件时遇到了问题...在vb中与此等效的代码是什么.

i got problem in raising event...what is equivalent code to this in vb..

c.OnImageCaptured += new EventHandler<CameraEventArgs>(c_OnImageCaptured);

调用此方法...

calling this method...

void c_OnImageCaptured(object sender, CameraEventArgs e)
        {
            if (button1.Enabled)
            {
                _b = e.Image;
                pictureBox1.Invalidate();
            }
        }
