Access Protected Excel File with ExcelDataReader and Epplus

问题

title pretty much says it all. Looking for a way to access a password protected excel file with ExcelDataReader and Epplus, can't find a proper answer.

If using ExcelDataReader, my code looks like

                excelStream = File.Open(excelFilePath, FileMode.Open, FileAccess.Read);
                excelReader = ExcelReaderFactory.CreateOpenXmlReader(excelStream);
                excelDataSet = excelReader.AsDataSet();

If using EPPlus my connection code looks like

            excelPackage = new ExcelPackage(new FileInfo(excelFilePath));
            excelWorkbook = excelPackage.Workbook;
            excelSheet = excelWorkbook.Worksheets[1];

EPPlus has some protection related methods but i can't figure out how to use them. ExcelDataReader doesnt seem to have any protection related methods.

Any tips appreciated, thanks.

EDIT: I do already know the password

回答1:

With EPPlus you can use

excelPackage = new ExcelPackage(new FileInfo(excelFilePath), "mypassword");

ExcelDataReader now supports opening password protected sheets. I opened an issue on their GitHub asking if they have such support and received a response saying that they do not, but after sometime they added support for some password methods. Details on the password methods they still do not support are in the link.

With ExcelDataReadr you can access your protected file like this:

var conf = new ExcelReaderConfiguration { Password = "yourPassword" };
excelReader = ExcelReaderFactory.CreateOpenXmlReader(excelStream, conf);
