Exemples

L’exemple de code suivant crée un Dictionary<TKey,TValue> vide de chaînes, avec des clés de chaîne, et y accède IDictionary<TKey,TValue> par le biais de l’interface.The following code example creates an empty Dictionary<TKey,TValue> of strings, with string keys, and accesses it through the IDictionary<TKey,TValue> interface.

L’exemple de code utilise Add la méthode pour ajouter des éléments.The code example uses the Add method to add some elements. L’exemple montre que la Add méthode ArgumentException lève une exception lors de la tentative d’ajout d’une clé dupliquée.The example demonstrates that the Add method throws ArgumentException when attempting to add a duplicate key.

L’exemple utilise la Item[TKey] propriété (l’indexeur dans C#) pour récupérer des valeurs, en montrant qu' KeyNotFoundException une exception est levée lorsqu’une clé demandée n’est pas présente, et montrant que la valeur associée à une clé peut être remplacée.The example uses the Item[TKey] property (the indexer in C#) to retrieve values, demonstrating that a KeyNotFoundException is thrown when a requested key is not present, and showing that the value associated with a key can be replaced.

L’exemple montre comment utiliser la TryGetValue méthode comme un moyen plus efficace pour récupérer des valeurs si un programme doit souvent essayer des valeurs de clés qui ne sont pas dans le dictionnaire, et comment utiliser la ContainsKey méthode pour tester si une clé existe avant d’appeler Addméthode.The example shows how to use the TryGetValue method as a more efficient way to retrieve values if a program often must try key values that are not in the dictionary, and how to use the ContainsKey method to test whether a key exists prior to calling the Add method.

Enfin, l’exemple montre comment énumérer les clés et les valeurs dans le dictionnaire et comment énumérer les valeurs uniquement à l’aide de Values la propriété.Finally, the example shows how to enumerate the keys and values in the dictionary, and how to enumerate the values alone using the Values property.

Remarques

L' IDictionary<TKey,TValue> interface est l’interface de base pour les collections génériques de paires clé/valeur.The IDictionary<TKey,TValue> interface is the base interface for generic collections of key/value pairs.

Chaque élément est une paire clé/valeur stockée dans KeyValuePair<TKey,TValue> un objet.Each element is a key/value pair stored in a KeyValuePair<TKey,TValue> object.

Chaque paire doit avoir une clé unique.Each pair must have a unique key. Les implémentations peuvent varier selon qu’elles key autorisent nullou non.Implementations can vary in whether they allow key to be null. La valeur peut être null et n’a pas besoin d’être unique.The value can be null and does not have to be unique. L' IDictionary<TKey,TValue> interface permet l’énumération des clés et des valeurs contenues, mais elle n’implique pas un ordre de tri particulier.The IDictionary<TKey,TValue> interface allows the contained keys and values to be enumerated, but it does not imply any particular sort order.

L' foreach instruction du C# langageFor Each (en Visual Basic, for each dans C++) retourne un objet du type des éléments dans la collection.The foreach statement of the C# language (For Each in Visual Basic, for each in C++) returns an object of the type of the elements in the collection. Étant donné que chaque élément IDictionary<TKey,TValue> de est une paire clé/valeur, le type d’élément n’est pas le type de la clé ou le type de la valeur.Since each element of the IDictionary<TKey,TValue> is a key/value pair, the element type is not the type of the key or the type of the value. Au lieu de cela, le KeyValuePair<TKey,TValue>type d’élément est.Instead, the element type is KeyValuePair<TKey,TValue>. Par exemple :For example:

for each(KeyValuePair<int, String^> kvp in myDictionary)
{
    Console::WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
foreach (KeyValuePair<int, string> kvp in myDictionary)
{
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
For Each kvp As KeyValuePair(Of Integer, String) In myDictionary
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value)
Next kvp

L' foreach instruction est un wrapper autour de l’énumérateur, qui autorise uniquement la lecture, et non l’écriture, de la collection.The foreach statement is a wrapper around the enumerator, which only allows reading from, not writing to, the collection.

Notes

Étant donné que les clés peuvent être héritées et que leur comportement a changé, leur unicité absolue ne peut Equals pas être garantie par des comparaisons à l’aide de la méthode.Because keys can be inherited and their behavior changed, their absolute uniqueness cannot be guaranteed by comparisons using the Equals method.

Notes pour les responsables de l’implémentation

La classe d’implémentation doit avoir un moyen de comparer des clés.The implementing class must have a means to compare keys.
