[API Proposal]: ToOrderedDictionary

[rampaa]

Background and motivation

We have ToDictionary, ToFrozenDictionary, ToImmutableDictionaryand ToImmutableSortedDictionary extension method for other dictionary types already. Having similar extension methods for OrderedDictionary would allow us to use OrderedDictionary in places where we use other dictionary types with the same level of convenience.

API Proposal

public static OrderedDictionary<TKey, TElement> ToOrderedDictionary<TSource, TKey, TElement>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector, Func<TSource, TElement> elementSelector) where TKey : notnull => ToOrderedDictionary(source, keySelector, elementSelector, null);
public static OrderedDictionary<TKey, TElement> ToOrderedDictionary<TSource, TKey, TElement>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector, Func<TSource, TElement> elementSelector, IEqualityComparer<TKey>? comparer) where TKey : notnull

API Usage

List<char> list = ['a', 'b', 'c'];
OrderedDictionary<char, double> orderedDictionary = list.ToOrderedDictionary(f => f, char.GetNumericValue);
