OleDbDataAdapter oleda = new OleDbDataAdapter(strSql, strCSVConnString);
DataTable dtbCSV = new DataTable();
oleda.Fill(dtbCSV);
return dtbCSV;
}
}
return null;// instead of null I want to return dtbCSV here
}
This gives an error "Error 45 'DirectDebit.Interbacs.CompanyUpload.ExcelToDatatable_dt1.get': not all code paths return a value". The error is due to the return statement which is not in the correct scope. But the problem is, I want to return dtbCSV and I am not able return that within the "get" scope as dtCSV does not exist within the get context, I have no knowledge of passing the values between scopes within a return method. Any help or an alternative way will be highly appreciated
