Domain.cs:
... public virtual double AktuellerKurs { get; set; } public virtual DateTime Datum { get; set;} public virtual DateTime Gültig { get; set; } public virtual int Id { get; set; } public virtual string ISOCode { get; set; } public virtual int Kursart { get; set; } public virtual double RealerKurs { get; set; } public virtual int WährungstabkurseId { get; set; } ...I get a NHibernate.QueryException ("could not resolve property: Datum.Date of: DaVinci.Domain.Waehrungskurs") when i call the following function:
public static Domain.Waehrungskurs GetByISOAndKursartAndDate(string isocode, int kursart, DateTime datum)
{
return (from WK in session.Linq<DaVinci.Domain.Waehrungskurs>()
where WK.ISOCode == isocode
&&
WK.Kursart == kursart
&&
WK.Datum.Date == datum.Date
orderby WK.Id descending
select WK).First();
}
When i delete the search-condition "WK.Datum.Date == datum.Date", the function works fine.
Any ideas why the property cannot be found?
The date-property of date time is not found because it's not implemented. Please write a patch for this class
The property isn't there.
Try replacing: WK.Datum.Date == datum.Date
with
WK.Datum == datum.Date
