Dictionary<TKey,TValue>.Comparer Dictionary<TKey,TValue>.Comparer Dictionary<TKey,TValue>.Comparer Dictionary<TKey,TValue>.Comparer Property

定義

取得 IEqualityComparer<T>,用於判斷字典的索引鍵是否相等。Gets the IEqualityComparer<T> that is used to determine equality of keys for the dictionary.

public:
 property System::Collections::Generic::IEqualityComparer<TKey> ^ Comparer { System::Collections::Generic::IEqualityComparer<TKey> ^ get(); };
public System.Collections.Generic.IEqualityComparer<TKey> Comparer { get; }
member this.Comparer : System.Collections.Generic.IEqualityComparer<'Key>
Public ReadOnly Property Comparer As IEqualityComparer(Of TKey)

屬性值

IEqualityComparer<T> 泛型介面實作,用於判斷目前 Dictionary<TKey,TValue> 的索引鍵是否相等,並提供索引鍵的雜湊值。The IEqualityComparer<T> generic interface implementation that is used to determine equality of keys for the current Dictionary<TKey,TValue> and to provide hash values for the keys.

備註

Dictionary<TKey,TValue>需要相等的實作為判斷索引鍵是否相等。Dictionary<TKey,TValue> requires an equality implementation to determine whether keys are equal. 您可以使用comparer接受參數的函IEqualityComparer<T>式來指定泛型介面的執行; 如果您未指定,則會使用預設的泛型相等比較EqualityComparer<T>.Default子。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 one, the default generic equality comparer EqualityComparer<T>.Default is used.

取得這個屬性的值是 O (1)運算。Getting the value of this property is an O(1) operation.
