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)
 {
        Excel_12.Application oExcel_12 = null;                //Excel_12 Application
        Excel_12.Workbook oBook = null;                       // Excel_12 Workbook
        Excel_12.Sheets oSheetsColl = null;                   // Excel_12 Worksheets collection
        Excel_12.Worksheet oSheet = null;                     // Excel_12 Worksheet
        Excel_12.Range oRange = null;                         // Cell or Range in worksheet
        Object oMissing = System.Reflection.Missing.Value;

        // Create an instance of Excel_12.
        oExcel_12 = new Excel_12.Application();

        // Make Excel_12 visible to the user.
        oExcel_12.Visible = true;

        // Set the UserControl property so Excel_12 won't shut down.
        oExcel_12.UserControl = true;

        // System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("en-US");

        // 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");

        // Export titles
        for (int j = 0; j < itemDataGridView.Columns.Count; j++)
        {
            oRange = (Excel_12.Range)oSheet.Cells[1, j + 1];
            oRange.Value2 = itemDataGridView.Columns[j].HeaderText;
        }

        // Export data
        for (int i = 0; i < itemDataGridView.Rows.Count - 1; i++)
        {
            for (int j = 0; j < itemDataGridView.Columns.Count; j++)
            {
                oRange = (Excel_12.Range)oSheet.Cells[i + 2, j + 1];
                oRange.Value2 = itemDataGridView[j, i].Value;
            }
        }

        // Release the variables.
        //oBook.Close(false, oMissing, oMissing);
        oBook = null;

        //oExcel_12.Quit();
        oExcel_12 = null;

        // Collect garbage.
        GC.Collect();
    }

这项工作对我来说..

oSheet = oBook.Worksheets.get_Item(index);

由于您从 Excel 获得了非英语异常文本，我假设没有名为“Sheet1”的工作表，而是具有本地化名称。您必须使用本地化名称，或者更好地使用工作表索引（应以 1 开头）而不是工作表名称。
