[70-536] - BitVector32 structure

Area di riferimento - Developing applications that use system types and collections    - Manage data in a .NET Framework application by using specialized collections. (Refer System.Collections.Specialized namespace)        - BitVector32 structure and BitVector32.Section structure BitVector32 structure La struttura BitVector32 permette di gestire a livello di bit un numero a 32 bit. Ecco un esempio di utilizzo: BitVector32 bit = new BitVector32(12);    // creo un vettore di bit il cui contenuto iniziale è il numero 12Console.WriteLine(bit.ToString());        // Output: BitVector32{00000000000000000000000000001100} // Costruzione delle maschere necessarie all'accesso agli elementi del vettore di bitint primoBit =...

[70-536] - Named Collections

Area di riferimento - Developing applications that use system types and collections    - Manage data in a .NET Framework application by using specialized collections. (Refer System.Collections.Specialized namespace)        - Named Collections           - NameObjectCollectionBase class           - NameObjectCollectionBase.KeysCollection class           - NameValueCollection class        - CollectionsUtil Named Collections La classe NameValueCollection deriva dalla classe astratta NameObjectCollectionBase e rappresenta un dizionario simile a StringDictionary. Tuttavia è permesso l'inserimento di più valori per chiave i quali possono essere acceduti mediante la chiave stessa o un indice. NameValueCollection d = new NameValueCollection(); // utilizzare l'indexer comporta la sovrascrittura del vecchio valore...

[70-536] - Specialized Dictionary

Area di riferimento - Developing applications that use system types and collections    - Manage data in a .NET Framework application by using specialized collections. (Refer System.Collections.Specialized namespace)        - Specialized Dictionary           - HybridDictionary class           - IOrderedDictionary interface and OrderedDictionary class           - ListDictionary class Specialized Dictionary La classe HybridDictionary implementa l'interfaccia IDictionary e utilizza un ListDictionary finchè la collezione è piccola per poi passare ad un Hashtable quando la collezione diventa grande. Questo stratagemma garantisce una migliore performance nell'accesso alla struttura dati. La classe si utilizza come un comune dizionario: HybridDictionary dizionario = new HybridDictionary();dizionario["x"] = 1;dizionario["y"] = 2;dizionario["z"]...

[70-536] - Specialized collections: Specialized String classes

Area di riferimento - Developing applications that use system types and collections    - Manage data in a .NET Framework application by using specialized collections. (Refer System.Collections.Specialized namespace)        - Specialized String classes            - StringCollection class            - StringDictionary class            - StringEnumerator class Specialized String classes La classe StringCollection permette di memorizzare una collezione di stringhe la cui dimensione può cambiare dinamicamente. La classe implementa le interfacce IList, ICollection, IEnumerable quindi si utilizza allo stesso modo di tutte le altre collection. StringCollection città = new StringCollection();città.Add("Milano");città.Add("Torino");città.Add("Roma"); // Enumero la collection mediante il costrutto foreach (consigliato)foreach (string c in città){   ...

[70-536] - Generic Collections: SortedDictionary and LinkedList

Area di riferimento - Developing applications that use system types and collections    - Improve type safety and application performance in a .NET Framework application by using generic collections. (Refer System.Collections.Generic namespace)       - Generic IComparable interface (Refer System Namespace)       - Generic IComparer interface and Generic IEqualityComparer interface       - Generic Comparer class and Generic EqualityComparer class       - Generic SortedDictionary class       - Generic LinkedList class       - Generic LinkedList.Enumerator structure       - Generic LinkedListNode class SortedDictionary class SortedDictionary è un dizionario generico che memorizza gli elementi ordinandoli in base al valore della chiave e implementa le interfacce IDictionary<TKey, TValue>,...

[70-536] - BitArray class

Area di riferimento - Developing applications that use system types and collections    - Manage a group of associated data in a .NET Framework application by using collections. (Refer System.Collections namespace)        - BitArray class BitArray class La classe BitArray è un collection ridimensionabile in grado di memorizzare valori booleani e consente di eseguire semplice operazioni logiche.Ecco un esempio di utilizzo: static void Main(){    BitArray a = new BitArray(3);  // creo un array di bit lungo 3    a[0] = true;    a[1] = true;    a[2] = true;     BitArray b = new BitArray(3);    b[0] = false;    b[1] = false;   ...
