Parameters

comparer IComparer<TKey>

The System.Collections.Generic.IComparer<TKey> implementation to use when comparing keys, or null to use the default System.Collections.Generic.Comparer<TKey> for the type of the key.

MultiValueSortedDictionary(IDictionary<TKey, TValue>)

Initializes a new instance of the KoderHack.MultiValueSortedDictionary<TKey,TValue> class that contains elements copied from the specified System.Collections.Generic.IDictionary<TKey,TValue> and uses the default System.Collections.Generic.IComparer<T> implementation for the key type.
