c# - HRESULT : 0x800A03EC Error while saving Excel file 异常

Question

我正在保存按钮点击事件的数据，下面是代码:

using Excel = Microsoft.Office.Interop.Excel;

Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
Excel.Range range;

object misValue = System.Reflection.Missing.Value;
String st = System.IO.Directory.GetCurrentDirectory() + "\\A.xlsx";

xlApp = new Excel.ApplicationClass();

xlWorkBook = xlApp.Workbooks.Open(st, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

int i = 6;
for (i = 6; i < 10; i++)
{
    xlWorkBook.SaveAs(st, XlFileFormat.xlExcel9795, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlShared, misValue, misValue, misValue, misValue, misValue);
MessageBox.Show(xlWorkSheet.get_Range("L" + @i, "L" + @i).Value2.ToString());
}

xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();

当我保存它时，它给了我错误:

HRESULT: 0x800A03EC Error while saving Excel file

Answer 1

检查工作表的单元格索引，从 [1,1] 开始sheet.cells[0,0] 将抛出 com 错误。
