[英]EPPlus - InsertRow: Row cannot be less than 1. Parameter name: value
I have an Excel template that has a table (range: A4:AM5) which I need to expand by inserting rows via EPPlus.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。 My code inserts the cell values in the file with no problem, but I need to extend the rows of the table according to each new value inserted in the first column.
我的代码在文件中插入单元格值没有问题,但我需要根据第一列中插入的每个新值扩展表的行。
I tried to use the InsertRow(5,1)
method but it shows an exception我尝试使用
InsertRow(5,1)
方法,但它显示异常
"System.ArgumentOutOfRangeException: 'Row cannot be less than 1. Parameter name: value'"
“System.ArgumentOutOfRangeException:'行不能小于 1。参数名称:值'”
And the value presents:价值呈现:
{System.ArgumentOutOfRangeException: Row cannot be less than 1. Parameter name: value > at OfficeOpenXml.ExcelCellAddress.set_Row(Int32 value) > at OfficeOpenXml.ExcelNamedRangeCollection.InsertRows(Int32 rowFrom, Int32 rows, ExcelNamedRange namedRange) > at OfficeOpenXml.ExcelNamedRangeCollection.Insert(Int32 rowFrom, Int32 colFrom, Int32 rows, Int32 cols, Func`2 filter) > at OfficeOpenXml.ExcelWorksheet.InsertRow(Int32 rowFrom, Int32 rows, Int32 copyStylesFromRow) > at TestInsertRow.Program.Main(String[] args)}
{System.ArgumentOutOfRangeException:Row 不能小于 1。参数名称:值 > 在 OfficeOpenXml.ExcelCellAddress.set_Row(Int32 value) > 在 OfficeOpenXml.ExcelNamedRangeCollection.InsertRows(Int32 rowFrom, Int32 rows, ExcelNamedRange namedOpenRange.>atOfficeOpenXml.ExcelNamedRangeCollection.InsertRows) > at OfficeOpenXml.ExcelNamedRangeCollection.InsertRows Insert(Int32 rowFrom, Int32 colFrom, Int32 rows, Int32 cols, Func`2 filter) > at OfficeOpenXml.ExcelWorksheet.InsertRow(Int32 rowFrom, Int32 rows, Int32 copyStylesFromRow) > at TestInsertRow.Program.Main(String[] args)}
I minimized the functions of the code into this one which also shows the same exception:我将代码的功能最小化到这个也显示相同的异常:

I faced the same exception and was able to resolve it by fixing the excel template names collection.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。
Press Ctrl+F3 (Name Manager) and search for names containing any #REF!按 Ctrl+F3(名称管理器)并搜索包含任何 #REF 的名称! values and referrers and delete them from the template.
值和引用,并从模板中删除它们。
If Ctrl + F3 doesn't work for finding Name Manager如果 Ctrl + F3 无法找到名称管理器
Hover over "sheet.Names" you will find all Name Managers And将鼠标悬停在“sheet.Names”上,您将找到所有名称管理器和
you can remove them throw code你可以删除它们抛出代码
var refName = sheet.Names.FirstOrDefault(x => x.Name == "nameOfNameManager");
if (refName != null)
{
sheet.Names.Remove("nameOfNameManager");
}
