Interop.Excel.Application ExportAsFixedFormat - 异常0x800A03EC

Question

当我尝试执行时，我得到异常'来自HRESULT的异常：0x800A03EC'。

// - Open the source workbook
excelDocument = excelApplication.Workbooks.Open(excelDocumentPath);

if (excelDocument != null)
{
      // - Save it in the target format
      excelDocument.ExportAsFixedFormat(paramExportFormat,
                                        pdfFile,
                                        paramExportQuality,
                                        paramIncludeDocProps,
                                        paramIgnorePrintAreas,
                                        paramFromPage,
                                        paramToPage,
                                        paramOpenAfterPublish,
                                        paramMissing);
}
