1、双击窗体（注意不是双击控件），加入代码：

public class Di

{

public static int D;

public static int s = 2;

}

void Add_food()

{

Label label = new Label();

label.Name = "Lab" + Di.s;

label.BackColor = System.Drawing.Color.Red;

label.Size = new System.Drawing.Size(10, 10);

label.Margin = new System.Windows.Forms.Padding(0);

label.ForeColor = System.Drawing.Color.Red;

label.AutoSize = false;

label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;

Random rd = new Random();

tag1:

label.Location = new System.Drawing.Point(rd.Next(0, 30) * 10, rd.Next(0, 30) * 10);

for (int i = 1; i < Di.s; i++)

{

Label lo = (Label)this.Controls.Find("Lab" + i, true)[0]; if (label.Location == lo.Location) goto tag1;

}

this.Controls.Add(label);

label.SendToBack();

panel1.SendToBack();

}

2、双击开始按钮，加入代码：

Add_food();

button1.Enabled = false;

如图所示：

3、双击timer1控件，加入代码：

if (Di.D == 1) { System.Windows.Forms.SendKeys.Send("{DOWN}"); return; };

if (Di.D == 2) { System.Windows.Forms.SendKeys.Send("{UP}"); return; };

if (Di.D == 3) { System.Windows.Forms.SendKeys.Send("{LEFT}"); return; };

if (Di.D == 4) { System.Windows.Forms.SendKeys.Send("{RIGHT}"); return; };

如图所示：

4、单击Form1，在属性中单击事件，找到KeyDown，双击，加入代码：

if (e.KeyCode == Keys.Down && Di.D != 2)

{

timer1.Enabled = false;

Di.D = 1;

Label lb = (Label)this.Controls.Find("Lab" + Di.s, true)[0];

Point[,] Lo = new Point[101, 101];

for (int i = 1; i <= Di.s; i++)

{

}

Label le = new Label();

le.Visible = false;

if (e.KeyCode == Keys.Down && Di.s > 2 && lbl.BackColor != System.Drawing.Color.Red && Lab1.Location.Y != 290)
