Methods

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<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<TKey,TValue>(ImmutableDictionary<TKey,TValue>.Builder)	Creates an immutable dictionary from the current contents of the builder's dictionary.
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.
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.
