Dictionary<TKey,TValue>.Values 屬性
重要

取得集合，包含 Dictionary<TKey,TValue> 中的值。
public:
property System::Collections::Generic::Dictionary<TKey, TValue>::ValueCollection ^ Values { System::Collections::Generic::Dictionary<TKey, TValue>::ValueCollection ^ get(); };C#
public System.Collections.Generic.Dictionary<TKey,TValue>.ValueCollection Values { get; }member this.Values : System.Collections.Generic.Dictionary<'Key, 'Value>.ValueCollectionPublic ReadOnly Property Values As Dictionary(Of TKey, TValue).ValueCollectionDictionary<TKey,TValue>.ValueCollection，包含 Dictionary<TKey,TValue> 中的值。
此程式代碼範例示範如何使用 屬性列舉字典 Values 中的值，以及如何列舉字典中的索引鍵和值。
此程式代碼範例是針對 Dictionary<TKey,TValue> 類別提供的較大範例的一部分， openWith (是本範例) 中使用的 Dictionary 名稱。
// 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);
}
C#
// 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);
}
C#
// 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
雖然 Dictionary<TKey,TValue>.ValueCollection 中值的順序並未指定，但此順序會與 Dictionary<TKey,TValue>.KeyCollection 屬性傳回之 Keys 中關聯索引鍵的順序相同。
傳 Dictionary<TKey,TValue>.ValueCollection 回的 不是靜態複本， Dictionary<TKey,TValue>.ValueCollection 而是會參考原始 Dictionary<TKey,TValue>中的值。 因此，對的變更 Dictionary<TKey,TValue> 會繼續反映在 中 Dictionary<TKey,TValue>.ValueCollection。
取得此屬性的值是 O (1) 作業。
