| Name | Description | |
|---|---|---|
  | Contains<TKey, TValue>(IImmutableDictionary<TKey, TValue>^, TKey, TValue) | Determines whether the specified immutable dictionary contains the specified key/value pair. |
| Create<TKey, TValue>() | Creates an empty immutable dictionary. |
| Create<TKey, TValue>(IEqualityComparer<TKey>^) | Creates an empty immutable dictionary that uses the specified key comparer. |
| Create<TKey, TValue>(IEqualityComparer<TKey>^, IEqualityComparer<TValue>^) | Creates an empty immutable dictionary that uses the specified key and value comparers. |
| CreateBuilder<TKey, TValue>() | Creates a new immutable dictionary builder. |
| CreateBuilder<TKey, TValue>(IEqualityComparer<TKey>^) | Creates a new immutable dictionary builder. |
| CreateBuilder<TKey, TValue>(IEqualityComparer<TKey>^, IEqualityComparer<TValue>^) | Creates a new immutable dictionary builder. |
| CreateRange<TKey, TValue>(IEnumerable<KeyValuePair<TKey, TValue>>^) | Creates a new immutable dictionary that contains the specified items. |
| CreateRange<TKey, TValue>(IEqualityComparer<TKey>^, IEnumerable<KeyValuePair<TKey, TValue>>^) | Creates a new immutable dictionary that contains the specified items and uses the specified key comparer. |
| CreateRange<TKey, TValue>(IEqualityComparer<TKey>^, IEqualityComparer<TValue>^, IEnumerable<KeyValuePair<TKey, TValue>>^) | Creates a new immutable dictionary that contains the specified items and uses the specified key comparer. |
| GetValueOrDefault<TKey, TValue>(IImmutableDictionary<TKey, TValue>^, TKey) | Gets the value for a given key if a matching key exists in the dictionary. |
| GetValueOrDefault<TKey, TValue>(IImmutableDictionary<TKey, TValue>^, TKey, TValue) | Gets the value for a given key if a matching key exists in the dictionary. |
| ToImmutableDictionary<TSource, TKey>(IEnumerable<TSource>^, Func<TSource, TKey>^) | Constructs an immutable dictionary from an existing collection of elements, applying a transformation function to the source keys. |
| ToImmutableDictionary<TSource, TKey>(IEnumerable<TSource>^, Func<TSource, TKey>^, IEqualityComparer<TKey>^) | Constructs an immutable dictionary based on some transformation of a sequence. |
| ToImmutableDictionary<TKey, TValue>(IEnumerable<KeyValuePair<TKey, TValue>>^) | Enumerates a sequence of key/value pairs and produces an immutable dictionary of its contents. |
| ToImmutableDictionary<TKey, TValue>(IEnumerable<KeyValuePair<TKey, TValue>>^, IEqualityComparer<TKey>^) | Enumerates a sequence of key/value pairs and produces an immutable dictionary of its contents by using the specified key comparer. |
| ToImmutableDictionary<TKey, TValue>(IEnumerable<KeyValuePair<TKey, TValue>>^, IEqualityComparer<TKey>^, IEqualityComparer<TValue>^) | Enumerates a sequence of key/value pairs and produces an immutable dictionary of its contents by using the specified key and value comparers. |
| ToImmutableDictionary<TSource, TKey, TValue>(IEnumerable<TSource>^, Func<TSource, TKey>^, Func<TSource, TValue>^) | Enumerates and transforms a sequence, and produces an immutable dictionary of its contents. |
| ToImmutableDictionary<TSource, TKey, TValue>(IEnumerable<TSource>^, Func<TSource, TKey>^, Func<TSource, TValue>^, IEqualityComparer<TKey>^) | Enumerates and transforms a sequence, and produces an immutable dictionary of its contents by using the specified key comparer. |
| ToImmutableDictionary<TSource, TKey, TValue>(IEnumerable<TSource>^, Func<TSource, TKey>^, Func<TSource, TValue>^, IEqualityComparer<TKey>^, IEqualityComparer<TValue>^) | Enumerates and transforms a sequence, and produces an immutable dictionary of its contents by using the specified key and value comparers. |
