C# 开发读二代证winform 出错，求助
我用c#开发一个winform，在点击按钮读卡出出错，提示：

                BoxPhoto.Image = card.objEDZ.PIC_Image;

                card.objEDZ.PIC_Byte = null;
                card.ReadICCardComplete -= new clsICCard.De_ReadICCardComplete(card_ReadICCardComplete);

            base.OnClosing(e);
        }

        void card_ReadICCardComplete(clsEDZ objEDZ)
        {
        }
    }
}


不知怎样办才好，请高手指点，先谢谢！
