c#task list waitall task waitany

上边的主线程会被卡住:

 7个同时开发,谁先完成之后, 需要完成某个工作,可以用waitany

2: 不卡界面的做法

加上以上命令就不卡,是子线程做的事

 

   //Task task = taskFactory.StartNew(action);
            Console.WriteLine("Eleven老师接到一个项目");
            Console.WriteLine("沟通需求，谈妥价格");

            Console.WriteLine("高级班筛选学员，组建团队");
            Console.WriteLine("详细的需求分析、系统设计、模块划分、框架搭建");
            Console.WriteLine("开始干活。。。");
            Console.WriteLine(" ");

            List<Task> taskList = new List<Task>();

            taskList.Add(taskFactory.StartNew(() => this.Coding("浑无痕", "Portal")));
            taskList.Add(taskFactory.StartNew(() => this.Coding(" 菜鸟 ", "BackService")));
            taskList.Add(taskFactory.StartNew(() => this.Coding("oldwork", "Client")));
            taskList.Add(taskFactory.StartNew(() => this.Coding("  米  ", "WeChatClient")));
            taskList.Add(taskFactory.StartNew(() => this.Coding("走自己的路", "  WCF  ")));
            taskList.Add(taskFactory.StartNew(() => this.Coding("滑猪小板", "  DB  ")));
            taskList.Add(taskFactory.StartNew(() => this.Coding("Walden", "小程序")));

            //都开发完成后，进行联调测试  不是我做的，是开发者

            taskFactory.ContinueWhenAny(taskList.ToArray(),
                t => Console.WriteLine("第一个完成的，获取红包奖励,{0}", Thread.CurrentThread.ManagedThreadId));

            taskFactory.ContinueWhenAll(taskList.ToArray(),
                tList => Console.WriteLine("都开发完成后，开始联调测试,{0}", Thread.CurrentThread.ManagedThreadId));

            Task.WaitAny(taskList.ToArray());//等待任意一个任务的完成，会卡主当前的运行线程
            Console.WriteLine("某个模块完成开发后，老师再收取20%的费用");

            Task.WaitAll(taskList.ToArray());//等待全部任务的完成，会卡主当前的运行线程


            Console.WriteLine("项目开发验收完成后，老师去收取全部的费用");
            Console.WriteLine("老师给大家分钱。。。");
