c# - ENUM を IQueryable に追加しようとしています

Question

それは空になり、データはありませんが、まだ匿名型と言っているようです。正常にコンパイルされ、データはまったく実行されません。これまでのご協力に感謝します

public IQueryable<RentPaidReportRecord> rptRentPaid(string daysFrom, string daysTo, int IN_SiteId, int IN_LandownerId, int IN_PaymentCategoryId, int IN_PaymentTypeId, string IN_ShowRelevantProportion, string IN_OutputFormat,string @IN_URL)
{

    DateTime IN_daysFrom = Convert.ToDateTime(daysFrom);
    DateTime IN_daysTo = Convert.ToDateTime(daysTo);

    var result = this._lmsDb.rptRentPaid(IN_daysFrom, IN_daysTo, IN_SiteId, IN_LandownerId, IN_PaymentCategoryId, IN_PaymentTypeId, IN_ShowRelevantProportion, IN_OutputFormat,IN_URL);

    // Need to add in ENUM PaymentCategory to the Output then add col to report, 19/8/2013
    // So i've decared paymentCategoryValues below, now need to join it to the SearchResults below
    // i.e. SearchResults.PaymentCategoryId = paymentCategoryValues.PaymentCategoryId
    //... and be able to Reference the description as Category in the SearchResults object
    // Being carefull not to change the IQueryable since its working at the moment just need enum desc col
    var paymentCategoryValues =
        Enum.GetValues(typeof(PaymentCategory)).Cast<PaymentCategory>().Select
            (r => new KeyValuePair<int, string>((int)r, r.ToDescription()));

    var searchResults = (from s in result
                         from c in paymentCategoryValues
                         where (IN_SiteId <= 0 || s.SiteId == IN_SiteId)
                                && (IN_LandownerId <= 0 || s.LandownerId == IN_LandownerId)
                                && (IN_PaymentCategoryId <= 0 || s.PaymentCategoryId == IN_PaymentCategoryId)
                                && (IN_PaymentTypeId <= 0 || s.PaymentTypeId == IN_PaymentTypeId)
                                && (s.PaymentCategoryId == c.Key)
                         select new RentPaidReportRecord
                         {
                             SiteId = s.SiteId,
                             LandownerId = s.LandownerId,
                             PaymentCategoryId = s.PaymentCategoryId,
                             PaymentTypeId = s.PaymentTypeId,
                             Category = c.Value.ToString()
                         });


        return searchResults.AsQueryable();
