How to make one loop animation in monogame(xna)?

Question

Update method at Animation class:

    public void Update(GameTime gameTime)
    {
        Timer += gameTime.ElapsedGameTime.Milliseconds;
        if (Timer > FrameTime){
            CurrentFrame++;
            if (CurrentFrame == TotalFrames)
            {
                CurrentFrame = 0;
                Done = true;
            }
            Timer = 0;
        }
    }

How to adapt this code to make animation single loop?

if (Timer > FrameTime && Done == false) {
