        Econ = new OleDbConnection(constr);

 ExcelConn(FilePath);
        Econ.Open();
        Query = string.Format("Select [Emp ID],[Emp Name],[Log Date],[LogTime],[Type] FROM [{0}]", "One Month Report$");
        OleDbCommand Ecom = new OleDbCommand(Query, Econ);
       

        DataSet ds = new DataSet();
        OleDbDataAdapter oda = new OleDbDataAdapter(Query, Econ);
        Econ.Close();
        oda.Fill(ds);
        DataTable Exceldt = ds.Tables[0];

        //creating object of SqlBulkCopy    
        SqlBulkCopy objbulk = new SqlBulkCopy(conn);
        //assigning Destination table name    
        objbulk.DestinationTableName = " Attendancetable";
        //Mapping Table column
        objbulk.ColumnMappings.Add("Emp ID", "Emp ID");
        objbulk.ColumnMappings.Add("Emp Name", "Emp Name");
        objbulk.ColumnMappings.Add("Log Date", "Log Date");
        objbulk.ColumnMappings.Add("LogTime", "LogTime");
        objbulk.ColumnMappings.Add("Type", "Type");
        //inserting Datatable Records to DataBase

C#

//
string HDR = hasHeaders ? "Yes" : "No";
           string constr ;
           if (FileName.Substring(FileName.LastIndexOf('.')).ToLower() == ".xlsx")
               constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FileName + ";Extended Properties=\"Excel 12.0;HDR=" + HDR + ";IMEX=0\"";
           else
               constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FileName + ";Extended Properties=\"Excel 8.0;HDR=" + HDR + ";IMEX=0\"";
