Exemplos

Este exemplo de código mostra como enumerar os valores no dicionário usando a propriedade Values e como enumerar as chaves e valores no dicionário.This code example shows how to enumerate the values in the dictionary using the Values property, and how to enumerate the keys and values in the dictionary.

Este exemplo de código faz parte de um exemplo maior fornecido para a classe Dictionary<TKey,TValue> (openWith é o nome do dicionário usado neste exemplo).This code example is part of a larger example provided for the Dictionary<TKey,TValue> class (openWith is the name of the Dictionary used in this example).

// To get the values alone, use the Values property.
Dictionary<String^, String^>::ValueCollection^ valueColl =
    openWith->Values;

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
Console::WriteLine();
for each( String^ s in valueColl )
{
    Console::WriteLine("Value = {0}", s);
}
// To get the values alone, use the Values property.
Dictionary<string, string>.ValueCollection valueColl =
    openWith.Values;

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
Console.WriteLine();
foreach( string s in valueColl )
{
    Console.WriteLine("Value = {0}", s);
}
' To get the values alone, use the Values property.
Dim valueColl As _
    Dictionary(Of String, String).ValueCollection = _
    openWith.Values

' The elements of the ValueCollection are strongly typed
' with the type that was specified for dictionary values.
Console.WriteLine()
For Each s As String In  valueColl
    Console.WriteLine("Value = {0}", s)
Next s
// When you use foreach to enumerate dictionary elements,
// the elements are retrieved as KeyValuePair objects.
Console::WriteLine();
for each( KeyValuePair<String^, String^> kvp in openWith )
{
    Console::WriteLine("Key = {0}, Value = {1}",
        kvp.Key, kvp.Value);
}
// When you use foreach to enumerate dictionary elements,
// the elements are retrieved as KeyValuePair objects.
Console.WriteLine();
foreach( KeyValuePair<string, string> kvp in openWith )
{
    Console.WriteLine("Key = {0}, Value = {1}", 
        kvp.Key, kvp.Value);
}
' When you use foreach to enumerate dictionary elements,
' the elements are retrieved as KeyValuePair objects.
Console.WriteLine()
For Each kvp As KeyValuePair(Of String, String) In openWith
    Console.WriteLine("Key = {0}, Value = {1}", _
        kvp.Key, kvp.Value)
Next kvp

Comentários

A ordem dos valores na Dictionary<TKey,TValue>.ValueCollection não é especificada, mas é a mesma ordem das chaves associadas na Dictionary<TKey,TValue>.KeyCollection retornada pela propriedade Keys.The order of the values in the Dictionary<TKey,TValue>.ValueCollection is unspecified, but it is the same order as the associated keys in the Dictionary<TKey,TValue>.KeyCollection returned by the Keys property.

O Dictionary<TKey,TValue>.ValueCollection retornado não é uma cópia estática; em vez disso, a Dictionary<TKey,TValue>.ValueCollection se refere aos valores no Dictionary<TKey,TValue>original.The returned Dictionary<TKey,TValue>.ValueCollection is not a static copy; instead, the Dictionary<TKey,TValue>.ValueCollection refers back to the values in the original Dictionary<TKey,TValue>. Portanto, as alterações no Dictionary<TKey,TValue> continuam a ser refletidas na Dictionary<TKey,TValue>.ValueCollection.Therefore, changes to the Dictionary<TKey,TValue> continue to be reflected in the Dictionary<TKey,TValue>.ValueCollection.

A obtenção do valor dessa propriedade é uma operação O(1).Getting the value of this property is an O(1) operation.
