C# - How can I correct string case in HashSet<string> within a Dictionary

Question

I have a variable like below:

var dict = new Dictionary<string, HashSet<string>>();

I want to make sure the values in the HashSet are unique using StringComparer.Ordinal. What would be the syntax for that? Thanks.

Everytime you initialize a new key, the value should be passed an explicit parameter like this:

dict["some key"] = new HashSet<string>(StringComparer.Ordinal);
