3.5.2会员升级规则
3.5.2.1会员升级规则主界面
当会员卡类别设置好后，会员卡还可以根据积分进行升级。这里是设置一个升级的规则，可以根据会员卡的等级高低进行排序和升级的设置，如当普通卡积分到600分时就可以升级为银卡，这里只能从低级的卡升至高级。积分是在收费录入时根据结账的多少进行积分的，只有是拥有会员卡的才能积分，积分规则：消费一元积分0.01分。
主界面截图：
3.5.2.1（图1）
从界面上可以看到我们这里用到的控件有：
| 控件名称 |
说明 |
| 按钮控件button |
第一要设置每个控件的Text，第二设置控件Name；不同的是dataGridView右键进行编辑列。 |
| 表格控件dataGridView |
查询功能实现：

界面显示的原卡类别升级前该卡所属的类别，升级后卡别是指经过积分规则升级后的卡的类别。升级后卡别不可以比原卡类别高级。
