Dictionary<TKey,TValue>.Comparer Property


Gets the IEqualityComparer<T> that is used to determine equality of keys for the dictionary.

 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)

Property Value

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.


Dictionary<TKey,TValue> requires an equality implementation to determine whether keys are equal. 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.

Getting the value of this property is an O(1) operation.
