have differance two queue

how to update new queue to Queue3

Queue Getupdate(Queue q1,Queue q2) { How... }

From stackoverflow

• The question is unclear; what is your desired result? The union? The intersection? What? If you want ("differance" [sic] in title) to return those in the original queue but not the second, perhaps (.NET 3.5):

  public static Queue<T> Except<T>(this Queue<T> original, Queue<T> remove)
  {
      return new Queue<T>(Enumerable.Except<T>(original,remove));
  }

  I am testing Function For Implement

  Marc Gravell : Yes, but what do you want the result to be? 5,6? then just use the code I posted earlier (perhaps swap the order - q3 = q2.Except(q1);)

  Marc Gravell : Note that using queues in this way is unusual; would a list / etc be more appropriate?

  Brian Rasmussen : You should edit your original question instead of posting updates in an answer.
