HashSet to Comma Delimited String

HashSet Coding Example: A HashSet is a collection that contains no duplicate elements.

Note: Tested in .NET 4.0.

       HashSet<string> myHashSet = new HashSet<string>();

       myHashSet.Add("A");

       myHashSet.Add("B");

       myHashSet.Add("B");

       myHashSet.Add("B");

       myHashSet.Add("B");

       myHashSet.Add("X");

       myHashSet.Add("Z");

       myHashSet.Add("B");

       myHashSet.Add("A");

       string commaDelimitedString = String.Join<string>(",", myHashSet);

       // commaDelimitedString is equal to "A,B,X,Z"
