c# - EPPlus - InsertRow:行不能小于 1。参数名称:值
问题描述
我有一个 Excel 模板,它有一个表格(范围:A4:AM5),我需要通过 EPPlus 插入行来扩展它。我的代码在文件中插入单元格值没有问题,但我需要根据插入第一列的每个新值来扩展表的行。
我尝试使用该InsertRow(5,1)
方法,但它显示异常
“System.ArgumentOutOfRangeException:'行不能小于 1。参数名称:值'”
价值呈现:
{System.ArgumentOutOfRangeException:行不能小于 1。参数名称:值 > 在 OfficeOpenXml.ExcelCellAddress.set_Row(Int32 值) > 在 OfficeOpenXml.ExcelNamedRangeCollection.InsertRows(Int32 rowFrom, Int32 rows, ExcelNamedRange namedRange) > 在 OfficeOpenXml.ExcelNamedRangeCollection。插入(Int32 rowFrom,Int32 colFrom,Int32 行,Int32 cols,Func`2 过滤器)> 在 OfficeOpenXml.ExcelWorksheet.InsertRow(Int32 rowFrom,Int32 行,Int32 copyStylesFromRow)> 在 TestInsertRow.Program.Main(String[] args)}
我将代码的功能最小化到这个也显示相同的异常:

解决方案
我遇到了同样的异常,并且能够通过修复 excel 模板名称集合来解决它。
按 Ctrl+F3(名称管理器)并搜索包含任何 #REF!值和引用者并将它们从模板中删除。
