Obtém um ICollection que contém os valores no IDictionary.

Valor da propriedade

ICollection

Um ICollection que contém os valores de IDictionary.

Implementações

Values

Exemplos

O exemplo de código a seguir mostra como usar a IDictionary.Values propriedade da System.Collections.IDictionary interface com um SortedList<TKey,TValue>, para listar os valores na lista classificada. O exemplo também mostra como enumerar os pares chave/valor na lista classificada; observe que o enumerador para a System.Collections.IDictionary interface retorna DictionaryEntry objetos em vez de KeyValuePair<TKey,TValue> objetos.

O exemplo de código faz parte de um exemplo maior, inclusive saída, fornecido para o método IDictionary.Add.

        // and access it using the IDictionary interface.
        //
        IDictionary openWith = new SortedList<string, string>();

        // Add some elements to the sorted list. There are no
        // duplicate keys, but some of the values are duplicates.
        // IDictionary.Add throws an exception if incorrect types
        // are supplied for key or value.
        openWith.Add("txt", "notepad.exe");
        openWith.Add("bmp", "paint.exe");
        openWith.Add("dib", "paint.exe");

Comentários

A ordem dos valores no ICollection é a mesma que a ordem no SortedList<TKey,TValue>.

A recuperação do valor dessa propriedade é uma operação O(1).
