请看看我写的有问题么？

Question

private void FirestAni_MouseEnter(object sender, MouseEventArgs e)
        {
            Thread t1 = new Thread(new ParameterizedThreadStart(Animation));
            t1.Start();
        }
void Animation()
        {
            while (true)
            {
                DoubleAnimation widthAnimation = new DoubleAnimation();
                widthAnimation.From = FirestAni.ActualWidth;
                widthAnimation.To = this.Width - 30;
                widthAnimation.AutoReverse = true;
                widthAnimation.Completed += animation_Completed;
                FirestAni.BeginAnimation(Button.WidthProperty, widthAnimation);
            }
        }报的错误是：No overload for 'Animation' matches delegate 'System.Threading.ParameterizedThreadStart'

Answer 1

private void FirestAni_MouseEnter(object sender, MouseEventArgs e) 
{ 
            Thread t1 = new Thread(Animation); //这里试试
            t1.Start(); 
} void Animation() 
        { 
            while (true) 
            { 
                DoubleAnimation widthAnimation = new DoubleAnimation(); 
                widthAnimation.From = FirestAni.ActualWidth; 
                widthAnimation.To = this.Width - 30; 
                widthAnimation.AutoReverse = true; 
                widthAnimation.Completed += animation_Completed; 
                FirestAni.BeginAnimation(Button.WidthProperty, widthAnimation); 
            } 
        } 

Answer 2

   Thread t1 = new Thread(new ParameterizedThreadStart(Animation)); 改成Thread t1 = new Thread(new ThreadStart(Animation));
