ClosedXML System.Exception:语法错误

Question

我使用ClosedXML从用户提供的输入中计算excel表中的值，并且在包含下列公式的单元格上出现错误

IF(C2=1，VLOOKUP(D7，A15:D28,4)，(IF(C2=2，VLOOKUP(D7，A33:D46,4)，VLOOKUP(D7，F15:I28，4)

在线：

lblResult.Text = worksheet.Cell("D8").Value;

你能帮我找出这里出了什么问题吗？

提前感谢

Answer 1

ClosedXML不支持VLOOKUP函数。

有关受支持函数的列表，请参见文档。

Answer 2

您可以使用worksheet.Cell("D8").CachedValue，根据计算结果，它将显示单元格中的值
