第C#使用Task實(shí)現(xiàn)并行編程Console.WriteLine($"...早起三件事完成,總耗時(shí){sw.Elapsed.Seconds}秒");

Console.ReadKey();

///summary

///穿衣

////summary

staticvoidDress()

Console.WriteLine($"穿衣開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:1));

sw.Stop();

Console.WriteLine($"...穿衣完成,耗時(shí){sw.Elapsed.Seconds}秒");

///summary

///刷牙

////summary

staticvoidBrushTeeth()

Console.WriteLine($"刷牙開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:3));

sw.Stop();

Console.WriteLine($"...刷牙完成,耗時(shí){sw.Elapsed.Seconds}秒");

///summary

///洗臉

////summary

staticvoidWashFace()

Console.WriteLine($"洗臉開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:5));

sw.Stop();

Console.WriteLine($"...系列完成,耗時(shí){sw.Elapsed.Seconds}秒");

}

運(yùn)行之后,等待一會(huì),會(huì)看到如下輸出:

早起三件事開始...

穿衣開始...

...穿衣完成,耗時(shí)1秒

刷牙開始...

...刷牙完成,耗時(shí)3秒

洗臉開始...

...系列完成,耗時(shí)5秒

...早起三件事完成,總耗時(shí)9秒

一件一件事慢慢來,總耗時(shí)9秒...

一看時(shí)間,哎呦我去,快遲到了,穿衣刷牙洗臉一起來吧...別問我現(xiàn)實(shí)中怎么實(shí)現(xiàn)的

總而言之代碼是這樣滴:

//Program.cs

usingSystem;

usingSystem.Diagnostics;

usingSystem.Threading;

usingSystem.Threading.Tasks;

namespaceConsoleApp1

classProgram

staticvoidMain(string[]args)

Console.WriteLine("早起三件事開始...");

Stopwatchsw=newStopwatch();

sw.Start();

TaskdressTask=Task.Factory.StartNew(action:Dress);

TaskbrushTeethTask=Task.Factory.StartNew(action:BrushTeeth);

TaskwashFaceTask=Task.Factory.StartNew(action:WashFace);

Task.WaitAll(dressTask,brushTeethTask,washFaceTask);

sw.Stop();

Console.WriteLine($"...早起三件事完成,總耗時(shí){sw.Elapsed.Seconds}秒");

Console.ReadKey();

///summary

///穿衣

staticvoidDress()

Console.WriteLine($"穿衣開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:1));

sw.Stop();

Console.WriteLine($"...穿衣完成,耗時(shí){sw.Elapsed.Seconds}秒");

///summary

staticvoidBrushTeeth()

Console.WriteLine($"刷牙開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:3));

sw.Stop();

Console.WriteLine($"...刷牙完成,耗時(shí){sw.Elapsed.Seconds}秒");

///summary

///洗臉

////summary

staticvoidWashFace()

Console.WriteLine($"洗臉開始...");

Stopwatchsw=newStopwatch();

sw.Start();

Thread.Sleep(timeout:TimeSpan.FromSeconds(value:5));

sw.Stop();

Console.WriteLine($"...系列完成,耗時(shí){sw.Elapsed.Seconds}秒");

}

啟動(dòng)運(yùn)行之后,等待一會(huì),你應(yīng)該會(huì)看到如下輸出:

早起三件事開始...

刷牙開始...

洗臉開始...

穿衣開始...

...穿衣完成,耗時(shí)1秒

...刷牙完成,耗時(shí)3秒

...系列完成,耗時(shí)5秒

...早起三件事完成,總耗時(shí)5秒

可以看到,幾件事一起干了,總耗時(shí)只用了5
