using System; using System.Threading.Tasks; class Program { static async Task Main(string[] args) { // 调用静态异步方法 Console.WriteLine("开始异步操作..."); await MyStaticAsyncMethod(); Console.WriteLine("异步操作后继续执行..."); } public static async Task MyStaticAsyncMethod() { // ...
3. 使用 Task 类 Task类是.NET 4.0引入的,用于简化异步和并行编程。Task提供了更高级的功能,如任务组合、取消、延续等。 usingSystem; usingSystem.Threading.Tasks; classProgram { staticasyncTaskMain(string[] args) { // 创建一个Task并启动 Task task = Task.Run(() => PrintNumbers()); // 主线程...
publicclassMainActivityextendsAppCompatActivity{MainAsyncTaskasyncTask;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);asyncTask=newMainAsyncTask();// 入参会被传递到doInBackground方法中,可以传递多个值asyncTask.execute(100);}...
查看AsyncTask的实现,会通过一个SerialExecutor串行线程池来对我们的任务进行排队,而这个SerialExecutor对象就是一个static final的常量。 具体的引用关系是: 1.我们的任务被封装在一个FutureTask的对象中(它充当一个runable的作用),FutureTask的实现也是通过内部类来实现的,因此它也为持有AsyncTask对象,而AsyncTask对象引用...
我有这个代码片段: static void Main(string[] args) { Observable.Range(1, 5).Subscribe(async x => await DoTheThing(x)); Console.WriteLine("done"); } static async Task DoTheThing(int x) { await Task.Delay(TimeSpan.FromSeconds(x)); Console.WriteLine(x); } 我希望它会循环5次,每次...
我们上述的三个步骤分别实现在三个对应的方法(TryGetFileInfo、ResolvePreconditionState和SendResponseAsync)中,所以StaticFileMiddleware的Invoke方法按照如下的方式先后调用这三个方法完整对整个请求的处理。 1:publicclassStaticFileMiddleware 2:{ 3:publicasync Task Invoke(HttpContext context) ...
//async_future_static_wait.dart文件 import 'dart:async'; void main() { print("main start"); //任务一 Future task1 = Future((){ print("task 1"); return 1; }); //任务二 Future task2 = Future((){ print("task 2"); return 2; ...

This paper extends the formalism of static single assignment (SSA) to intro- duce a program representation called task static single assignment (T-SSA). The new representation integrates the copy-on-write renaming across tasks with the con- ventional SSA renaming within a task. This position ...
