Add `ToDictionary` extensions on `IDictionary` by Copilot · Pull Request #41 · Tyrrrz/PowerKit

Copilot · 2026-04-17T06:57:08Z

Ports ToDictionary extensions from CliFx, enabling typed conversion of a non-generic IDictionary to Dictionary<TKey, TValue>.

Changes

DictionaryExtensions.cs: New file with an extension(IDictionary) block containing two overloads:
- ToDictionary<TKey, TValue>(IEqualityComparer<TKey> comparer) — casts each DictionaryEntry to the typed key/value pair and delegates to Enumerable.ToDictionary with the given comparer.
- ToDictionary<TKey, TValue>() — uses EqualityComparer<TKey>.Default as the comparer.
DictionaryExtensionsTests.cs: Covers result type, comparer identity, and key/value contents for both overloads.

Usage

IDictionary raw = new Hashtable { ["one"] = 1, ["two"] = 2 };

// With explicit comparer
Dictionary<string, int> typed = raw.ToDictionary<string, int>(StringComparer.OrdinalIgnoreCase);

// With default comparer
Dictionary<string, int> typed = raw.ToDictionary<string, int>();
