代码

导入的命名空间

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading;using System.Threading.Tasks;using System.Windows.Forms;

初始化私有变量

private string[] red = { "01","02","03","04","05","06",        "07","08","09","10","11","12","13","14","15","16","17"};        private string[] blue = {"01","02","03","04","05","06",        "07","08","09","10" };        private bool begin = true;

页面初始化

private void Form1_Load(object sender, EventArgs e)        {                        foreach(var item in groupBox1.Controls)            {                if(item is Label)                {                    ((Label)item).Text = "00";                                 }            }            button2.Enabled = false;        }

开始按钮

private void button1_Click(object sender, EventArgs e)        {            button1.Text = "已经开始";            button1.Enabled = false;            button2.Enabled = true;            begin = true;            TaskFactory f = new TaskFactory();            List<Task> list = new List<Task>();            foreach(var item in groupBox1.Controls)            {                if(item is Label)                {                    ((Label)item).Text = "00";                }            }            foreach( var item in groupBox1.Controls)            {                if(item is Label)                {                    Label lbl = item as Label;                    list.Add(f.StartNew(() =>                    {                        Random r = new Random();                        while (begin)                        {                            string txt = "";                            if (lbl.Name.Contains("Red"))                            {                                lock (obj)                                {                                                                        txt = red[r.Next(0, 17)];                                    Update(lbl, txt);                                                                    }                            }                            else                            {                                txt = blue[r.Next(0, 10)];                                Update(lbl, txt);                            }                            Thread.Sleep(10);                        }                    }));                }            }            f.ContinueWhenAll(list.ToArray(), tList => this.ShowResult());        }

数字更新

private void Update(Label label , string text)        {            this.Invoke(new Action(() =>            {                label.Text = text;            }));        }

结束按钮

private void button2_Click(object sender, EventArgs e)        {            button1.Text = "开始";            button1.Enabled = true;            button2.Enabled = false;            begin = false;        }

结果显示

private void ShowResult()        {            StringBuilder s = new StringBuilder();            s.Append(lblRed1.Text + " ");            s.Append(lblRed2.Text + " ");            s.Append(lblRed3.Text + " ");            s.Append(lblRed4.Text + " ");            s.Append(lblRed5.Text + " ");            s.Append(lblRed6.Text + " \n");            s.Append($"blueBob: {lblBlue.Text}");            MessageBox.Show(s.ToString());        }
