Date OleAut invalid

Nov 9, 2010 at 10:51 PM

Hello, I'm trying to use an Excel spreadsheet template and when I try to retrieve the worksheet appears the error: "Date OLEAUT invalid". The code used is:

bool exportou = false;
string path = Constante.PathArquivosTemplateRelatorios + "template.xlsx";
FileInfo template = new FileInfo(path);

if (template.Exists == true)
    using (ExcelPackage p = new ExcelPackage(template, true))
        int startRow = 2;

        ExcelWorksheet ws = p.Workbook.Worksheets[1];
        int row = startRow;

//Population data...

        //Get the documet as a byte array from the stream and save it to disk.
        Byte[] bin = p.GetAsByteArray();

        string file = Constante.PathArquivosTemplateRelatorios + "\\sample4.xlsx";
        File.WriteAllBytes(file, bin);
        exportou = true;

Does anyone know what happens?

I have to look at your file to see whats wrong. Create an issue and upload it or send me notification if you want to send it by mail.

Hi, ok I do not know what is wrong with the file. An important is that the template file was generated on another machine. To solve my problem I generated a new file template from scratch and give the error no longer appeared.
