ExceptWith removes the specified elements from the source set.
Here, we strip all vowels from the set:
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
class Sample
{
public static void Main()
{
var letters = new HashSet("the quick brown fox");
letters.ExceptWith("aeiou");
foreach (char c in letters)
Console.Write(c);
}
}
The output:
