初始化代码
界面效果如下：
实现旋转是使用的改变控件大小，背景颜色(把padding设置4可以看见背景颜色)。
1 Random random = new Random();
2 SoundPlayer sp = new SoundPlayer(Resources.Untitled_Project);
3 int circle;
4 int index;
5 int stopNum;
6 bool flag = true;//奇数和偶数的标志，为true表示偶数
7 private void Button_Click(object sender, EventArgs e)
8 {
9 circle = random.Next(5, 8);//随机产生旋转的圈数
10 stopNum = random.Next(0, 8);//随机确定选择抽中奖品的下标
11 button.Enabled = false;
12 time.Interval = 10;
13 index = 0;
14 flag = true;
15 sp.Play();
16 time.Start();
17 }
18
19 private void time_Tick(object sender, EventArgs e)
20 {
21 if (flag)//放大picturebox，实现转动效果
22 {
23 pictures[index].Size = new Size(103, 103);
24 pictures[index].BackColor = Color.YellowGreen;
25 flag = false;
26 }
27 else if (flag == false)//将原来的picturebox缩放回原来的尺寸
28 {
29 pictures[index].Size = new Size(95, 95);
30 pictures[index].BackColor = Color.White;
31 index++;
32 flag = true;
33 }
34 if (index == 8)
35 {
36 index = 0;
37 circle -= circle > 0 ? 1 : 0;//每次转动8次，旋转的圈数-1
38 }
39 //倒数两圈慢
40 time.Interval = circle > 2 ? 10 : 100;
41 if (circle == 0 && index == stopNum)
42 {
43 pictures[index].Size = new Size(103, 103);
44 pictures[index].BackColor = Color.YellowGreen;
45 pictures[index].Location = new Point(pictures[index].Location.X - 4, pictures[index].Location.Y - 4);
46 StopRotate(index);
47 pictures[index].Size = new Size(95, 95);
48 pictures[index].BackColor = Color.White;
49 pictures[index].Location = new Point(pictures[index].Location.X + 4, pictures[index].Location.Y + 4);
50 }
51 }
旋转代码
停止再加上一个简单的概率会有点不了不流畅。
1 private void StopRotate(int sum)
2 {
3 string message = null;
4 switch (index)
5 {
6 case 0: if (random.Next(0, 2) == stopNum) message = "恭喜获取保温杯一个"; else { circle = 1; stopNum = 2; } break;//1/2 14 7%
7 case 1: if (random.Next(0, 3) == stopNum) message = "恭喜获取体重秤一个"; else { circle = 1; stopNum = 5; } break;//1/3 21 4%
8 case 2: message = "谢谢惠顾"; break;
9 case 3: if (random.Next(3, 7) == stopNum) message = "恭喜获取台灯一个"; else { circle = 1; stopNum = 5; } break;//1/4 28 3%
10 case 4: if (random.Next(0, 5) == stopNum) message = "恭喜获取耳机一个"; else { circle = 1; stopNum = 5; } break;//1/4 28 3%
11 case 5: message = "谢谢惠顾"; break;
12 case 6: if (random.Next(6, 8) == stopNum) message = "恭喜获取电动牙刷一个"; else { circle = 1; stopNum = 2; } break;//1/2 1/14 7&
13 case 7: if (random.Next(7, 10) == stopNum) message = "恭喜获取时钟一个"; else { circle = 1; stopNum = 2; } break;//1/3 1/21 4%
14 }
15 if (message != null)
16 {
17 sp.Stop();
18 time.Stop();//先关闭定时器
19 MessageBox.Show(message);
20 this.button.Enabled = true;
21 }
22 }
停止代码
简单的旋转程序就完成了。
