CLR attributumokban sajnos nem lehet haszn\u00e1lni nullable t\u00edpusokat, mivel ezeket metaadatk\u00e9nt t\u00e1rolja el a compiler, \u00e9s az nincs felk\u00e9sz\u00edtve strukt\u00far\u00e1kra. Igaz\u00e1b\u00f3l m\u00e9g a decimalt sem eszi, ami el\u00e9g bosszant\u00f3, ez az\u00e9rt belef\u00e9rhetett volna.
\nMost m\u00e9gis kellett nullable \u00e9s r\u00e1ad\u00e1sul decimal att param, \u00edgy ker\u00fcltem ki:<\/p>\n

Nem eleg\u00e1ns, de m\u0171k\u00f6dik. Valakinek van jobb \u00f6tlete?<\/p>\n
K\u00e9s\u0151bb, amikor kiveszem a property-k \u00e9rt\u00e9k\u00e9t, akkor n\u00e9zem meg, mi null \u00e9s mi nem, valamint akkor konvert\u00e1lok decimalra. A double-decimal konverzi\u00f3 okozhat adatveszt\u00e9st, de ismerem milyen sz\u00e1mok mennek be, ezekkel nincs ilyen gond.<\/p>\n","protected":false},"excerpt":{"rendered":"
