重庆海天软件工程学院的WINFORM实训项目-抽奖系统
最近班上写了一个关于winform的实训小项目(抽奖系统)，90%的代码都在下面，感觉还不错，所以贴出来分享一下，希望能帮倒大家
所有界面如下：
这是自己写的一个公共类：

大图片的后台代码(用户控件)：

小图片的后台代码(用户控件):
View Code
using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class ScrollNumSmall : UserControl { private int num=0;//最后显示的数 private int degree;//定义滚动次数 private int maxImgIndex = 9;//要显示的数字最大值(0-maxImgIndex) private int step;//滚动的步长 public int MaxImgIndex { set { maxImgIndex = value; } } public int Num { set { num = value; } } public ScrollNumSmall() { step = new Random().Next(40, 50);//步长为随机数，让图片滚动不同步 InitializeComponent(); this.pbNumber.Image = imgNumber.Images[0];//设置图片框的初始图片为0 } private void timer1_Tick(object sender, EventArgs e) { pbNumber.Location =new Point(pbNumber.Location.X,pbNumber.Location.Y + step) ;//每次移动20 if (pbNumber.Location.Y > this.Size.Height)//如果移到控件处，则把图片放到最上面 { pbNumber.Location = new Point(pbNumber.Location.X, -pbNumber.Size.Height); degree--;//减少滚动次数 if (degree < 7) { timer1.Interval += 5;//最后6圈开始减速，移动时间每次多加6ms } if (degree > 1) { //换图 Random r = new Random(); int imgIndex = r.Next(0, maxImgIndex+1); this.pbNumber.Image = imgNumber.Images[imgIndex]; } else { this.pbNumber.Image=imgNumber.Images[num];//最后一次显示实际数字 timer1.Stop();//停止timer1,timer2开始接管跑最后一圈 timer2.Start(); timer2.Interval = timer1.Interval; } } } /// <summary> /// 图片开始滚动，自动停止 /// </summary> public void Start() { Random r = new Random(); degree = new Random().Next(50,60);//设置滚动次数 timer1.Start(); } private void timer2_Tick(object sender, EventArgs e) { if (pbNumber.Location.Y > 0) { pbNumber.Location = new Point(pbNumber.Location.X, 1); timer2.Stop(); } else { pbNumber.Location = new Point(pbNumber.Location.X, pbNumber.Location.Y + step-8); timer2.Interval += 5; } } } }
幸运奖的后台代码(用户控件)：
View Code
using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { /// <summary> /// 变换的数字 /// </summary> public partial class JupNumber : UserControl { private int num = 0;//定义最终的数字，默认为0 private int degree = 80; public int Degree { set { degree = value; } } public int Num { set { num = value; } } private string headNum = "53500";//数字前面固定部位 public JupNumber() { degree = new Random().Next(80, 100); InitializeComponent(); } /// <summary> /// 开始跳动 /// </summary> public void Start() { timer1.Stop(); timer1.Start(); this.Enabled = false; } /// <summary> /// 停止跳动，将显示数字定位在最终数字上 /// </summary> public void Stop() { timer1.Stop(); this.lblNumber.Text = headNum + NumberManage.FormatNum(num); this.Enabled = true; } private void timer1_Tick(object sender, EventArgs e) { Random r = new Random(); lblNumber.Text = headNum + NumberManage.FormatNum(r.Next(1, 481)); degree--; if (degree < 0) { this.Stop(); } } private void lblNumber_Click(object sender, EventArgs e) { if (MessageBox.Show("重摇此数？", "重置提示", MessageBoxButtons.YesNo) == DialogResult.Yes) { this.num = NumberManage.GetLukyNumber(); this.Degree = 70; this.Start(); } } } }
一等奖窗体的后台代码：
View Code
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class FirstAwardForm : Form { public FirstAwardForm() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { GoGoGo(); } /// <summary> /// 开始摇奖 /// </summary> private void GoGoGo() { btnStart.Enabled = false; btnRestar.Enabled = true; int lukyNum = NumberManage.GetWondfulNumber(1);//得到一个幸运数 //把幸运数分解出个位，十位和百位 int one = NumberManage.AnalyzeNum(lukyNum, 1);//个位 int two = NumberManage.AnalyzeNum(lukyNum, 2);//十位 int three = NumberManage.AnalyzeNum(lukyNum, 3);//百位 snFirstNum.Num = one; snSecondNum.Num = two; snThirdNum.Num = three; snThirdNum.MaxImgIndex = 4;//百位上的数最大为4 snFirstNum.timer1.Interval = 3; snSecondNum.timer1.Interval = 5; snThirdNum.timer1.Interval = 7; snFirstNum.Start(); snSecondNum.Start(); snThirdNum.Start(); } private void btnRestar_Click(object sender, EventArgs e) { if (MessageBox.Show("你确定放弃此号码，重新摇一次？", "重置提示", MessageBoxButtons.YesNo) == DialogResult.Yes) { btnStart.Enabled = true; btnRestar.Enabled = false; } } } }
二、三等奖后台类似，就不贴出来了，下面是幸运奖窗体的后台代码：
View Code
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class LukyForm : Form { private int[] lukyNum = new int[15];//15个号码 public LukyForm() { InitializeComponent(); //LukyNumInit(); //JupNumberInit(); } /// <summary> /// 初始化幸运数字数组 /// </summary> private void LukyNumInit() { for (int i = 0; i < lukyNum.Length; i++) { lukyNum[i] = NumberManage.GetLukyNumber(); } } /// <summary> /// 初始化所有JupNumber要显示的数字 /// </summary> private void JupNumberInit() { int i = 0; foreach (Control jup in this.Controls) { if (jup is JupNumber) { ((JupNumber)jup).Num = lukyNum[i]; i++; } } } private void button1_Click(object sender, EventArgs e) { this.button1.Enabled = false; LukyNumInit(); JupNumberInit(); foreach (Control jup in this.Controls) { if (jup is JupNumber) { ((JupNumber)jup).Start(); } } } } }
