来源：网络收集 点击： 时间：2024-09-02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); if (label.Location == lo.Location) goto tag1;
}
this.Controls.Add(label);
label.SendToBack();
panel1.SendToBack();
}
如图所示：
2/5双击开始按钮，加入代码：
Add_food();
button1.Enabled = false;
如图所示：
3/5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：
4/5单击Form1，在属性中单击事件，找到KeyDown，双击，加入代码：
