Answer 1

I'm going to assume you're using this http://exceldatareader.codeplex.com/

From your code:

if (upprice.FileName.Contains(".xlsx"))
 {
  IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
   DataSet result = excelReader.AsDataSet();
 }
 else if (upprice.FileName.Contains(".xls"))
 {
  IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
  DataSet result = excelReader.AsDataSet();
 } 

these tests are backwards. ".xlsx" files are zipped xml documents. "xls" are the older binary files. Also consider using System.IO.Path.GetExtension() to get the file extension since you'll notice Contains(".xls") is true for both file types.
