可以說商品的折扣率是連貫整個系統的中樞，每個病人的醫療的費用都要根據該商品是否設置到折扣的問題，按照不同的醫療方式商品設置不同的折扣，在病人消費的時候根據病人的醫療方式進行對應的折扣。
打開設置商品折扣價
界面如（圖1）：可以對一個商品打勾，點擊單個保存，也可以全選點擊批量保存，進行設置折扣率如（圖2）

設置窗口的實現，因爲折扣類型的不定的變化，根據醫院可能會增加或者減少折扣類型，所以爲了適應，只能用動態來實現。

string Name = dt.Rows[i]["DiscountTypeName"].ToString().Trim();
myGraphics.DrawString(Name,new Font("宋體", 10, FontStyle.Regular),
