C# winfrm中做的来回漂动窗口问题！

Question

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;namespace floatingForm
{
    public partial class FloatingForm : Form
    {
        public FloatingForm()
        {
            InitializeComponent();
        }        private void timer1_Tick(object sender, EventArgs e)
        {
            Point p = new Point(0,370);
            //p.X = this .DesktopLocation .X ;
            while (this .DesktopLocation .X  <=0)
            {
                for (int i = 0; i < this.DesktopBounds.Width; i++)
                {
                    Point p1 = new Point(this.DesktopLocation.X + 1, this.DesktopLocation.Y);
                    this.DesktopLocation = p1;
                    //p = p1;
                }
                if (this.DesktopLocation.X == this.DesktopBounds.Width)
                {
                    for (int i = this.DesktopBounds.Width; i > 0; i++)
                    {
                        //Point p2 = new Point(20, 370);
                        //this.DesktopLocation = p2;                        Point p2 = new Point(this.DesktopLocation.X - 1, this.DesktopLocation.Y);                        this.DesktopLocation = p2;
                    }
                    
                }                this.DesktopLocation = p;            }
          
                     }        private void FloatingForm_Load(object sender, EventArgs e)
        {
            Point p = new Point(0, 370);
            this.DesktopLocation = p;
        }      
    }
}
在程序运行时，只能够来回一次，我想做的是能够不断自动来回的，想了好半天还是没头绪，小弟我是初学者，希望有哪位大大能够帮忙解答一下，非常感谢！！！

        }
    }
}

设置一下x,y坐标，分别判断xy的边界值，然后写个for语句实现x++，Y++，X--，y--就行了
