Egenskapsvärde

Implementeringar

Exempel

I följande kodexempel visas hur du använder IDictionary.Values egenskapen för System.Collections.IDictionary gränssnittet med en SortedDictionary<TKey,TValue>, för att lista värdena i ordlistan. Exemplet visar också hur du räknar upp nyckel/värde-paren i ordlistan. Observera att uppräknaren System.Collections.IDictionary för gränssnittet returnerar DictionaryEntry objekt i stället KeyValuePair<TKey,TValue> för objekt.

Kodexemplet är en del av ett större exempel, inklusive utdata, som tillhandahålls IDictionary.Add för metoden.

Kommentarer

Värdena i den returnerade ICollection sorteras enligt Comparer egenskapen och garanteras vara i samma ordning som motsvarande nycklar i den ICollection som returneras av Keys egenskapen.

Att hämta värdet för den här egenskapen är en O(1)-åtgärd.
