You can create a dictionary from an IEnumerable<T> , including an array, via:

var dictionary = myEnumerable.ToDictionary(element => element.Key,
                                           element => element.Value)

where Key and Value are the key and value you want to store in each dictionary element. Available in .NET Framework 3.5+/.NET Core 1.0+/.NET 5.0+. Official documentation.

If you want the dictionary values to be the elements from the original enumerable:

   var dictionary = myEnumerable.ToDictionary(element => element.Key)

If you only need high-performance set operations, you may be able to use:

var words = new HashSet<string>(listOfStrings);

In simple terms, the HashSet class can be thought of as a Dictionary<TKey,TValue> collection without values. Official documentation.
