我在下面设置了一个案例语句，查看学生年（stuyear）（最终将由 asp.net 控件触发。该案例设置为在将结果输出到三列时将其包含在计算中。但是，如果我将stuyearwithin的值maindata从 11 更改为 10，如下面的输出列返回 0。该语句似乎只对前三种情况有效，然后最后六个它返回 0，就好像它们被忽略了一样。
我想要发生的是stuyear当belowexpected,asexpected和aboveexpected.
如果可以避免的话，我不想为第 9 年、第 10 年和第 11 年设置单独的列并触发它们在 VB.net 中的可见性。
/*Progress*/您可以在下面的示例中的注释下找到我所指的特定代码。
