        string conString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR=YES'";
        conString = string.Format(conString, file);
        DataTable dt = new DataTable();
        using (OleDbConnection connExcel = new OleDbConnection(conString))
        {
            using (OleDbCommand cmdExcel = new OleDbCommand())
            {
                using (OleDbDataAdapter odaExcel = new OleDbDataAdapter())
                {

                    //Get the name of First Sheet.
                    connExcel.Open();
                    DataTable dtExcelSchema;
                    dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                    string sheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
                    connExcel.Close();
