Dictionary<TKey,TValue>.Values 屬性

定義

命名空間:

System.Collections.Generic

組件:

netstandard.dll, System.Collections.dll

來源:

Dictionary.cs

會得到包含 中 Dictionary<TKey,TValue>值的集合。

public:
 property System::Collections::Generic::Dictionary<TKey, TValue>::ValueCollection ^ Values { System::Collections::Generic::Dictionary<TKey, TValue>::ValueCollection ^ get(); };

public System.Collections.Generic.Dictionary<TKey,TValue>.ValueCollection Values { get; }

member this.Values : System.Collections.Generic.Dictionary<'Key, 'Value>.ValueCollection

Public ReadOnly Property Values As Dictionary(Of TKey, TValue).ValueCollection

屬性值

Dictionary<TKey,TValue>.ValueCollection

包含 中的 數值 Dictionary<TKey,TValue>ADictionary<TKey,TValue>.ValueCollection。

範例

此程式碼範例展示了如何使用 Values 屬性枚舉字典中的值，以及如何枚舉字典中的鍵與值。

此程式碼範例是該類別更大 Dictionary<TKey,TValue> 範例的一部分（openWith 此範例中使用的字典名稱）。

// 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();
foreach( string s in valueColl )
{
    Console.WriteLine("Value = {0}", s);
}

// To get the values alone, use the Values property.
let valueColl = openWith.Values

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
printfn ""

for s in valueColl do
    printfn $"Value = {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();
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.
printfn ""

for kvp in openWith do
    printfn $"Key = {kvp.Key}, Value = {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

備註

中Dictionary<TKey,TValue>.ValueCollection值的順序未明確，但與屬性回傳Keys的Dictionary<TKey,TValue>.KeyCollection相關鍵順序相同。

回傳 Dictionary<TKey,TValue>.ValueCollection 的 不是靜態副本;而是 Dictionary<TKey,TValue>.ValueCollection 回溯到原始 Dictionary<TKey,TValue>中的值。 因此，變化 Dictionary<TKey,TValue> 會持續反映在 Dictionary<TKey,TValue>.ValueCollection中。

取得此性質的值需進行 O（1） 運算。
