  public DataSet ExcelToDS(string Path)
  {
   string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +"Data Source="+ Path +";"+"Extended Properties=Excel 8.0;";
   OleDbConnection conn = new OleDbConnection(strConn);
   conn.Open();  
   string strExcel = "";   
   OleDbDataAdapter myCommand = null;
   DataSet ds = null;
   strExcel="select * from [sheet1$]";
   myCommand = new OleDbDataAdapter(strExcel, strConn);
   ds = new DataSet();
   myCommand.Fill(ds,"table1");   
   return ds;
  }
