public class HashSetDictionary<TKey, TValue> : ISetDictionary<TKey, TValue>, ICollectionDictionary<TKey, TValue, ISet<TValue>>, IReadOnlyDictionary<TKey, ISet<TValue>>, IReadOnlyCollection<KeyValuePair<TKey, ISet<TValue>>>, ICollection<KeyValuePair<TKey, ISet<TValue>>>, IEnumerable<KeyValuePair<TKey, ISet<TValue>>>, IEnumerable where TKey : notnull

Type Parameters

Name	Description
TKey	The type of the keys in the dictionary.
TValue	The type of the values in the dictionary.

Constructors

Name	Description
HashSetDictionary()	Initializes a new instance of the HashSetDictionary<TKey, TValue> class.
HashSetDictionary(IEqualityComparer<TKey>?, IEqualityComparer<TValue>?)	Initializes a new instance of the HashSetDictionary<TKey, TValue> class that uses the specified key and value comparers.
HashSetDictionary(int)	Initializes a new instance of the HashSetDictionary<TKey, TValue> class with the specified initial capacity for key/value set pairs.
HashSetDictionary(int, IEqualityComparer<TKey>?, IEqualityComparer<TValue>?)	Initializes a new instance of the HashSetDictionary<TKey, TValue> class with the specified initial capacity for key/value set pairs, and uses the specified key and value comparers.

Properties

Name	Description
Count	Gets the number of keys and associated value sets in the dictionary.
this[TKey]	Gets the value list associated with the specified key. If the key is not found then a new value list is returned which can be used to add values to the key or to monitor when items are added to the key.
KeyComparer	Gets the comparer that is used to determine equality of the keys.
Keys	Gets a collection containing the keys in the dictionary.
ValueComparer	Gets the comparer that is used to determine equality of the values.
ValueCount	Gets the number of values in the dictionary across all keys.
ValueSets	Gets a collection containing the value sets in the dictionary.
Values	Gets a collection containing all the values in the dictionary across all the keys.

Methods

Name	Description
Clear()	Clears all keys and values from the dictionary and associated value sets.
Clear(TKey)	Clears the values in the set associated with the specified key and removes the key from the dictionary.
Contains(TKey, TValue)	Returns a value indicating whether the specified key and associated value are present in the dictionary.
ContainsKey(TKey)	Returns a value indicating whether the dictionary contains the specified key.
ContainsValue(TValue)	Returns a value indicating whether any of the value sets in the dictionary contain the specified value.
EnsureCapacity(int)	Ensures that the dictionary can hold up to a specified number of key/value set pairs without any further expansion of its backing storage.
GetEnumerator()	Returns an enumerator that iterates through the value sets in the dictionary.
GetValueCount(TKey)	Gets the number of values in the dictionary associated with the specified key or zero if the key is not present.
TrimExcess(bool)	Sets the key/value set pair capacity of this dictionary to what it would be if it had been originally initialized with all its entries, and optionally trims all the value sets in the dictionary as well.
TrimExcess(int, bool)	Sets the key/value set pair capacity of this dictionary to hold up to a specified number of entries without any further expansion of its backing storage, and optionally trims the capacity of each value set to the actual number of values in the list.
TryGetValues(TKey, out ValueSet)	Gets the value set for the specified key or null if the key was not found.

Explicit Interface Implementations

Name	Description
ICollectionDictionary<TKey, TValue, ISet<TValue>>.this[TKey]	Gets the value list associated with the specified key. If the key is not found then a new value list is returned which can be used to add values to the key or to monitor when items are added to the key.
ICollectionDictionary<TKey, TValue, ISet<TValue>>.Keys	Gets a collection containing the keys in the dictionary.
ICollectionDictionary<TKey, TValue, ISet<TValue>>.TryGetValues(TKey, out ISet<TValue>)	Gets the value set for the specified key or null if the key was not found.
ICollectionDictionary<TKey, TValue, ISet<TValue>>.ValueCollections	Gets a collection containing the value sets in the dictionary.
ICollectionDictionary<TKey, TValue, ISet<TValue>>.Values	Gets a collection containing all the values in the dictionary across all the keys.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.Add(KeyValuePair<TKey, ISet<TValue>>)	Not supported.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.Clear()	Not supported.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.Contains(KeyValuePair<TKey, ISet<TValue>>)	Gets a value indicating whether the specified key and value set is present in the dictionary.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.CopyTo(KeyValuePair<TKey, ISet<TValue>>[], int)	Copies the key and value set pairs to an array starting at the given array index.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.IsReadOnly	Gets a value indicating whether this collection is read-only. Although this dictionary is not read-only, this always returns true as only read operations are supported through the ICollection<T> interface.
ICollection<KeyValuePair<TKey, ISet<TValue>>>.Remove(KeyValuePair<TKey, ISet<TValue>>)	Not supported.
IEnumerable<KeyValuePair<TKey, ISet<TValue>>>.GetEnumerator()	Returns an enumerator that iterates through the value sets in the dictionary.
IReadOnlyDictionary<TKey, ISet<TValue>>.this[TKey]	Gets the value list associated with the specified key. If the key is not found then a new value list is returned which can be used to add values to the key or to monitor when items are added to the key.
IReadOnlyDictionary<TKey, ISet<TValue>>.Keys	Gets a collection containing the keys in the dictionary.
IReadOnlyDictionary<TKey, ISet<TValue>>.TryGetValue(TKey, out ISet<TValue>)	Gets the value set for the specified key or null if the key was not found.
IReadOnlyDictionary<TKey, ISet<TValue>>.Values	Gets a collection containing the value sets in the dictionary.
IEnumerable.GetEnumerator()	Returns an enumerator that iterates through the value sets in the dictionary.
