Obtiene una interfaz ICollection que contiene los valores de la interfaz IDictionary.

property System::Collections::ICollection ^ System::Collections::IDictionary::Values { System::Collections::ICollection ^ get(); };
System.Collections.ICollection System.Collections.IDictionary.Values { get; }
member this.System.Collections.IDictionary.Values : System.Collections.ICollection
 ReadOnly Property Values As ICollection Implements IDictionary.Values

Valor de propiedad

ICollection

ICollection que contiene los valores de IDictionary.

Implementaciones

Values

Ejemplos

En el ejemplo de código siguiente se muestra cómo usar la IDictionary.Values propiedad de la System.Collections.IDictionary interfaz con , SortedList<TKey,TValue>para enumerar los valores de la lista ordenada. En el ejemplo también se muestra cómo enumerar los pares clave-valor en la lista ordenada; Tenga en cuenta que el enumerador de la System.Collections.IDictionary interfaz devuelve DictionaryEntry objetos en lugar de KeyValuePair<TKey,TValue> objetos .

El ejemplo de código forma parte de un ejemplo más grande, incluido el resultado, proporcionado para el IDictionary.Add método .

        //
        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("bmp", "paint.exe");

Comentarios

El orden de los valores de ICollection es el mismo que el orden de .SortedList<TKey,TValue>

La recuperación del valor de esta propiedad es una operación O(1).
