4個PictureBox ,4個Timer控件 然後把下面的複製上即可：
public partial class Form1 : Form
{
public int x1 = 8;
public int x2 = 148;
public int x3 = 248;
public int x4 = 348;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.timer1.Enabled = true;
this.timer2.Enabled = true;
this.timer3.Enabled = true;
this.timer4.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
pictureBox1.Location = new Point(x1,8);
x1 += 1;
if (x1 >= this.Size.Width)
{
x1 = 0;
}
}
private void timer2_Tick(object sender, EventArgs e)
{
pictureBox2.Location = new Point(x2,56);
x2 += 1;
if (x2 >= this.Size.Width)
{
x2 = 0;
}
}
private void timer3_Tick(object sender, EventArgs e)
{
pictureBox3.Location = new Point(x3,112);
x3 += 1;
if (x3 >= this.Size.Width)
{
x3 = 0;
}
}
private void timer4_Tick(object sender, EventArgs e)
{
pictureBox4.Location = new System.Drawing.Point(x4,176);
x4 += 1;
if (x4 >= this.Size.Width)
{
x4 = 0;
}
}
}
