public IEqualityComparer<TKey> Comparer { get; }

Property Value

Type: System.Collections.Generic.IEqualityComparer<TKey>

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.
