为什么我在最后一列 "Total_Monthly_Amount" 中得到“0”值？

Question

作为计算值和公式得到零也存在。我的本意是根据 EmployeeId 按金额分组。我想对最后一列使用自动计算方法，但是当我尝试创建文件时它显示为零。

FORMULA 也存在于相应的“0”值字段中。

我用的是EPPLUS 4.0，还设置了公式：

如代码所示

"IF(" + currentCell + "=" + previousCell + ",\"\",SUMIF(B:B," + currentCell + ",I:I))";

第一个“0”的值将是“18000” 而不是第二个“0”值将是“32987” 等等。

Answer 1

Yes.I 刚刚将 ToString() 转换为 Int32() 以获得 AMOUNT 字段值。

workSheet.Cells[j + 2, k + 1].Value = Convert.ToInt32(ds.Tables[0].Rows[j].ItemArray[k]);

为什么我在最后一列 "Total_Monthly_Amount" 中得到“0”值？

Why I am getting "0" value in a last column "Total_Monthly_Amount"?
