Recreating a Dictionary from an IEnumerable<KeyValuePair<>>
Solution 1:
If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:
Dictionary<string, ArrayList> result = target.GetComponents()
.ToDictionary(x => x.Key, x => x.Value);
There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.
Solution 2:
As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>) now exists.
