当我将 Excel 导出到 C# 时出现错误,我找不到我的代码错误的地方以及我的问题的解决方案
错误 :
GestãoSI.exe 中出现“System.Runtime.InteropServices.COMException”类型的未处理异常
附加信息:Índice inválido。(HRESULT 例外:0x8002000B (DISP_E_BADINDEX))
代码运行时出现错误
// Add a workbook.
oBook = oExcel_12.Workbooks.Add(oMissing);
// Get worksheets collection
oSheetsColl = oExcel_12.Worksheets;
// Get Worksheet "Sheet1"
oSheet = (Excel_12.Worksheet)oSheetsColl.get_Item("Sheet1");
这是我所有的代码
public static void ExportDataGridViewTo_Excel12(DataGridView itemDataGridView)
