本人要做一个程序， 交互式窗口，手动输入100个数据，求平均值、平方后再开方和自动分类，
程序功能：1、手动指定录入1-100任意个数据，数据类型double；
2、计算录入的数据个数n；
3、求n个数据的平均值；
4、n个数据每一个与其平均值的差；
5、第4步计算的每一个数据平方再开方，这个值假定代号为X；
6、第5步计算的值分类，分五类：A+类：X≥1.67；A类：1.33≤X<1.67；B类：1.0≤X<1.33；C类：0.67≤X<1.0；D类：X<0.67。
程序界面如图中所示要求，我做到了求和，但不会统计textbox有效数据个数，做不到后面的功能， 求高手指点迷津！！！
程序代码如下：
