- Source:
- FrozenDictionary.cs
Creates a FrozenDictionary<TKey,TValue> with the specified key/value pairs.
public static System.Collections.Frozen.FrozenDictionary<TKey,TValue> ToFrozenDictionary<TKey,TValue> (this System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<TKey,TValue>> source, System.Collections.Generic.IEqualityComparer<TKey>? comparer = default);static member ToFrozenDictionary : seq<System.Collections.Generic.KeyValuePair<'Key, 'Value>> * System.Collections.Generic.IEqualityComparer<'Key> -> System.Collections.Frozen.FrozenDictionary<'Key, 'Value><Extension()>
Public Function ToFrozenDictionary(Of TKey, TValue) (source As IEnumerable(Of KeyValuePair(Of TKey, TValue)), Optional comparer As IEqualityComparer(Of TKey) = Nothing) As FrozenDictionary(Of TKey, TValue)Type Parameters
- TKey
The type of the keys in the dictionary.
- TValue
The type of the values in the dictionary.
Parameters
- source
- IEnumerable<KeyValuePair<TKey,TValue>>
The key/value pairs to use to populate the dictionary.
- comparer
- IEqualityComparer<TKey>
The comparer implementation to use to compare keys for equality. If null, Default is used.
Returns
A FrozenDictionary<TKey,TValue> that contains the specified keys and values.
Remarks
If the same key appears multiple times in the input, the last one in the sequence takes precedence. This differs from ToDictionary, where duplicate keys result in an exception.
