我有一个 Excel 表,我需要遍历每一行,如果它符合某些条件,则将数据放入几个不同的数组之一中。行数是动态的。我在声明数组长度时遇到了一些问题。我可以简单地遍历行,检查我想要的条件,并保持有多少行适合条件 A、条件 B 或条件 C,并使用它来重新调整数组,但有没有更简单的方法?
谢谢!
您没有告诉我们您的“声明数组长度的问题”。我的猜测是您正在从一个范围加载数组,这意味着该行是您无法使用 ReDim 更改的第一个维度。
根据我的猜测,我在下面提供了两种方法。如果这些方法都没有帮助,请返回更完整的解释。
方法一
将整个范围加载到单个数组中,然后使用第二个数组来记录类型。
Dim AllTypes() As Variant
Dim RowCrnt As Long
Dim RowType() As Long
AllTypes = EntireRange.Value
Redim RowType(LBound(AllTypes,1) TO UBound(AllTypes,1))
For RowCrnt = LBound(AllTypes,1) TO UBound(AllTypes,1)
' Classify Row
RowType(RowCrnt) = X
Next
方法二
锯齿状阵列可能更符合您的要求。
我将 Sheet1 设置为如下所示:
我运行下面的宏,它首先对每一行进行分类并将其放在适当的数组中。然后它将每个数组输出到即时窗口以给出:
a b c d e f g h i j
b c d e f g h i j k
c d e f g h i j k l
a b c d e f g h i j
b c d e f g h i j k
c d e f g h i j k l
1 2 3 4 5
2 3 4 5 6
3 4 5 6 7
1 2 3 4 5
2 3 4 5 6
3 4 5 6 7
a 1 b 2 c 3
b 2 c 3 d 4
c 3 d 4 e 5
a 1 b 2 c 3
b 2 c 3 d 4
c 3 d 4 e 5
