範例

下列程式碼範例會建立空Dictionary<TKey,TValue>之字串的字串索引鍵,並使用Add方法來加入一些項目。The following code example creates an empty Dictionary<TKey,TValue> of strings with string keys and uses the Add method to add some elements. 此範例示範Add方法會擲回ArgumentException時嘗試要加入重複的索引鍵。The example demonstrates that the Add method throws an ArgumentException when attempting to add a duplicate key.

此範例會使用Item[TKey]屬性 (C# 中為索引子) 來擷取值,示範KeyNotFoundException要求的索引鍵不存在,而且可以取代顯示索引鍵關聯的值時擲回。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.

該示例顯示如何使用TryGetValue方法作為更有效的方式來檢索值,如果程序通常必須嘗試不在字典中的鍵值,並且它顯示如何使用ContainsKey方法來測試在調用 Add方法。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 it shows how to use the ContainsKey method to test whether a key exists before calling the Add method.

此範例示範如何列舉的索引鍵和字典中的值以及如何列舉索引鍵,並單獨使用值Keys屬性和Values屬性。The example shows how to enumerate the keys and values in the dictionary and how to enumerate the keys and values alone using the Keys property and the Values property.

最後,此範例示範Remove方法。Finally, the example demonstrates the Remove method.

備註

Dictionary<TKey,TValue>泛型類別提供將一組索引鍵對應至一組值。The Dictionary<TKey,TValue> generic class provides a mapping from a set of keys to a set of values. 加入字典中的每一個項目都是由值及其關聯索引鍵所組成。Each addition to the dictionary consists of a value and its associated key. 使用其索引鍵擷取值,是非常快速,關閉 o (1),因為Dictionary<TKey,TValue>類別會實作為雜湊表。Retrieving a value by using its key is very fast, close to O(1), because the Dictionary<TKey,TValue> class is implemented as a hash table.

注意

擷取的速度取決於指定的類型雜湊演算法的品質TKeyThe speed of retrieval depends on the quality of the hashing algorithm of the type specified for TKey.

只要物件使用中的索引鍵為Dictionary<TKey,TValue>,它必須變更任何會影響其雜湊值的方式。As long as an object is used as a key in the Dictionary<TKey,TValue>, it must not change in any way that affects its hash value. 在每個索引鍵Dictionary<TKey,TValue>必須是唯一根據字典的相等比較子。Every key in a Dictionary<TKey,TValue> must be unique according to the dictionary's equality comparer. 金鑰不能null,值可以是,如果但其類型TValue是參考型別。A key cannot be null, but a value can be, if its type TValue is a reference type.

Dictionary<TKey,TValue> 需要一個等號比較實作,來判斷索引鍵是否相等。Dictionary<TKey,TValue> requires an equality implementation to determine whether keys are equal. 您可以指定實作IEqualityComparer<T>泛型介面使用的建構函式可接受comparer參數,如果您未指定預設泛型等號比較子實作,EqualityComparer<T>.Default用。You can specify an implementation of the IEqualityComparer<T> generic interface by using a constructor that accepts a comparer parameter; if you do not specify an implementation, the default generic equality comparer EqualityComparer<T>.Default is used. 如果型別TKey實作System.IEquatable<T>泛型介面的預設相等比較子會使用該實作。If type TKey implements the System.IEquatable<T> generic interface, the default equality comparer uses that implementation.

注意

例如,您可以使用所提供的不區分大小寫的字串比較子StringComparer類別來建立具有不區分大小寫的字串索引鍵的字典。For example, you can use the case-insensitive string comparers provided by the StringComparer class to create dictionaries with case-insensitive string keys.

營運Dictionary<TKey,TValue>是的項目數Dictionary<TKey,TValue>可以保存。The capacity of a Dictionary<TKey,TValue> is the number of elements the Dictionary<TKey,TValue> can hold. 當項目新增至Dictionary<TKey,TValue>,自動增加容量的要求以重新配置內部陣列。As elements are added to a Dictionary<TKey,TValue>, the capacity is automatically increased as required by reallocating the internal array.

僅限.NET framework: 針對非常大型Dictionary<TKey,TValue>物件,您可以藉由設定增加到 64 位元系統上的 2 億個元素的最大容量enabled屬性 <gcAllowVeryLargeObjects> 組態項目true中執行階段環境。.NET Framework only: For very large Dictionary<TKey,TValue> objects, you can increase the maximum capacity to 2 billion elements on a 64-bit system by setting the enabled attribute of the <gcAllowVeryLargeObjects> configuration element to true in the run-time environment.

基於列舉的詳細資訊,在字典中的每個項目會被視為KeyValuePair<TKey,TValue>結構,表示值和其索引鍵。For purposes of enumeration, each item in the dictionary is treated as a KeyValuePair<TKey,TValue> structure representing a value and its key. 傳回任何項目順序未定義。The order in which the items are returned is undefined.

foreach C# 語言的陳述式 (for each c + + For Each Visual Basic 中) 傳回集合中的項目類型的物件。The foreach statement of the C# language (for each in C++, For Each in Visual Basic) returns an object of the type of the elements in the collection. 因為Dictionary<TKey,TValue>是索引鍵和值、 項目類型的集合不是索引鍵的類型或值的類型。Since the Dictionary<TKey,TValue> is a collection of keys and values, the element type is not the type of the key or the type of the value. 相反地,項目型別是KeyValuePair<TKey,TValue>了索引鍵的型別和實值型別。Instead, the element type is a KeyValuePair<TKey,TValue> of the key type and the value type. 例如:For example:

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

foreach陳述式是一個列舉值,以允許僅讀取集合,不寫入包裝函式。The foreach statement is a wrapper around the enumerator, which allows only reading from the collection, not writing to it.

注意

因為可繼承索引鍵,並變更其行為,其絕對唯一性無法保證使用比較Equals方法。Because keys can be inherited and their behavior changed, their absolute uniqueness cannot be guaranteed by comparisons using the Equals method.

執行緒安全性

ADictionary<TKey,TValue>可支援多個讀取器同時,只要不修改集合。A Dictionary<TKey,TValue> can support multiple readers concurrently, as long as the collection is not modified. 即便如此,透過集合列舉是本質上並非安全執行緒程序。Even so, enumerating through a collection is intrinsically not a thread-safe procedure. 在極少數的案例,其中列舉競用權限寫入,就必須在整個列舉期間鎖定集合。In the rare case where an enumeration contends with write accesses, the collection must be locked during the entire enumeration. 若要讓多重執行緒能夠存取集合以便進行讀取和寫入,您必須實作自己的同步處理。To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.

具備執行緒安全的替代方案,請參閱 <<c0> ConcurrentDictionary<TKey,TValue> 類別或ImmutableDictionary<TKey,TValue>類別。For thread-safe alternatives, see the ConcurrentDictionary<TKey,TValue> class or ImmutableDictionary<TKey,TValue> class.

公用靜態 (Shared Visual Basic 中) 的這種類型的成員都是安全執行緒。Public static (Shared in Visual Basic) members of this type are thread safe.
