IDictionary<TKey,TValue> Interface

Definição

Representa uma coleção genérica de pares chave/valor.Represents a generic collection of key/value pairs.

generic <typename TKey, typename TValue>
public interface class IDictionary : System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<TKey, TValue>>, System::Collections::Generic::IEnumerable<System::Collections::Generic::KeyValuePair<TKey, TValue>>
public interface IDictionary<TKey,TValue> : System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<TKey,TValue>>, System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<TKey,TValue>>
type IDictionary<'Key, 'Value> = interface
    interface ICollection<KeyValuePair<'Key, 'Value>>
    interface seq<KeyValuePair<'Key, 'Value>>
    interface IEnumerable
Public Interface IDictionary(Of TKey, TValue)
Implements ICollection(Of KeyValuePair(Of TKey, TValue)), IEnumerable(Of KeyValuePair(Of TKey, TValue))

Parâmetros de tipo

TKey

O tipo de chaves no dicionário.The type of keys in the dictionary.

TValue

O tipo de valores no dicionário.The type of values in the dictionary.

Exemplos

O exemplo de código a seguir cria Dictionary<TKey,TValue> um vazio de cadeias de caracteres, com chaves de cadeia e IDictionary<TKey,TValue> o acessa por meio da 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.

O exemplo de código usa Add o método para adicionar alguns elementos.The code example uses the Add method to add some elements. O exemplo demonstra que o Add método gera ArgumentException ao tentar adicionar uma chave duplicada.The example demonstrates that the Add method throws ArgumentException when attempting to add a duplicate key.

O exemplo usa a Item[TKey] Propriedade (o indexador em C#) para recuperar valores, demonstrando que um KeyNotFoundException é gerado quando uma chave solicitada não está presente e mostrando que o valor associado a uma chave pode ser substituído.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.

O exemplo mostra como usar o TryGetValue método como uma maneira mais eficiente de recuperar valores se um programa geralmente deve experimentar valores de chave que não estão no dicionário e como usar o ContainsKey método para testar se uma chave existe antes de chamar o Addmétodo.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.

Por fim, o exemplo mostra como enumerar as chaves e valores no dicionário e como enumerar os valores sozinhos usando a Values propriedade.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.

Comentários

A IDictionary<TKey,TValue> interface é a interface base para coleções genéricas de pares chave/valor.The IDictionary<TKey,TValue> interface is the base interface for generic collections of key/value pairs.

Cada elemento é um par de chave/valor armazenado em KeyValuePair<TKey,TValue> um objeto.Each element is a key/value pair stored in a KeyValuePair<TKey,TValue> object.

Cada par deve ter uma chave exclusiva.Each pair must have a unique key. As implementações podem variar se permitirem key. nullImplementations can vary in whether they allow key to be null. O valor pode ser null e não precisa ser exclusivo.The value can be null and does not have to be unique. A IDictionary<TKey,TValue> interface permite que as chaves contidas e os valores sejam enumerados, mas não implica nenhuma ordem de classificação específica.The IDictionary<TKey,TValue> interface allows the contained keys and values to be enumerated, but it does not imply any particular sort order.

A foreach instrução do C# idiomaFor Each (em Visual Basic, for each in C++) retorna um objeto do tipo dos elementos na coleção.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. Como cada elemento de IDictionary<TKey,TValue> é um par chave/valor, o tipo de elemento não é o tipo da chave ou o tipo do valor.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. Em vez disso, o tipo KeyValuePair<TKey,TValue>de elemento é.Instead, the element type is KeyValuePair<TKey,TValue>. Por exemplo: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

A foreach instrução é um wrapper em volta do enumerador, que permite somente a leitura, não a coleção.The foreach statement is a wrapper around the enumerator, which only allows reading from, not writing to, the collection.

Observação

Como as chaves podem ser herdadas e seu comportamento alterado, sua exclusividade absoluta não pode ser garantida por comparações usando o Equals método.Because keys can be inherited and their behavior changed, their absolute uniqueness cannot be guaranteed by comparisons using the Equals method.

Notas aos Implementadores

A classe de implementação deve ter um meio de comparar as chaves.The implementing class must have a means to compare keys.
