错误来源在这里：

The error source is here:

Dim tmp As Integer = 0

使用Excel，单元格索引从'1'开始。

抱歉，错过了增量。



因为错误是通用的，所以很难检测到来源。



我建议检查所有涉及的对象是否有效。

另一项检查可能是先尝试读取单元格。

With Excel, cell indexes start at '1'.
Sorry, missed the increment.

Because the error is generic, it is difficult to detect the source.

I suggest to check if all involved objects are valid.
Another check might be trying to read the cell first.
