仅当我尝试将c＃中的.xls中的文件另存为.xlsx时，才出现此错误。仅当我尝试从IIS 7.0运行时才会发生
The file could not be accessed. Try one of the following:
• Make sure the specified folder exists.
• Make sure the folder that contains the file is not read-only.
• Make sure the file name does not contain any of the following characters: < > ? [ ] : | or *
• Make sure the file/path name doesn't contain more than 218 characters.
The file could not be accessed. Try one of the following:
根据我的情况，该路径存在，文件夹和文件不是只读的，不包含任何这些字符，并且不超过218个字符。
当我在本地运行具有以下文件路径和文件名的项目时，它可以工作
"\\localhost\inetpub\wwwroot\ABC\GeneratedReports\Financial\Ageing_XXXX XXXX XXXXXX XXXXXX XXX_10_15548312.xls"
如果将路径再次更改为以下，则会出现该错误
"C:\inetpub\wwwroot\ABC\Generatedreports\Financial\Ageing_XXXX XXXX XXXXXX XXXXXX XXX_10_15548312.xls"
这是我用来转换这些excel文件的代码段
Excel.Application excelApp = new Excel.Application();
Excel.Workbook xlWorkbook_temp = excelApp.Workbooks.Open(strSavePath, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
xlWorkbook_temp.SaveAs(Filename: strSavePath2, FileFormat: Microsoft.Office.Interop.Excel.XlFileFormat.xlOpenXMLWorkbook);
xlWorkbook_temp.Close();
