一 不带参数 ThreadPool.QueueUserWorkItem(delegate { PostDataWhenLoadData(); }); private void PostDataWhenLoadData...SysnShowError(br); } } 二 带参数 string ti = “”; ThreadPool.QueueUserWorkItem
今天在博客园拜读了 蒋金楠，难道调用ThreadPool.QueueUserWorkItem（）的时候，真是必须调用Thread.Sleep（N）吗？自己也深有启发，决定再次陈述个人理解。...}; //遍历输出结果 foreach (var action in actions) { ThreadPool.QueueUserWorkItem...foreach (var action in actions) { var Tempaction = action; ThreadPool.QueueUserWorkItem
开门见山，下面的例子中通过调用ThreadPool.QueueUserWorkItem(WaitCallback callBack, object state)的方式实现异步调用： 1: class...Console.WriteLine("A4")); 10: 11: foreach (var action in actions) 12: { 13: ThreadPool.QueueUserWorkItem...Console.WriteLine("A4")); 10: 11: foreach (var action in actions) 12: { 13: ThreadPool.QueueUserWorkItem...所以正确的写法是： 1: foreach (var action in actions) 2: { 3: var a = action; 4: ThreadPool.QueueUserWorkItem
(o => this.DoSomethingLong("参数1")); ThreadPool.QueueUserWorkItem(o => this.DoSomethingLong...ThreadPool.QueueUserWorkItem(o => this.DoSomethingLong("参数4")); ThreadPool.QueueUserWorkItem...ThreadPool.QueueUserWorkItem(o => this.DoSomethingLong("参数8")); ThreadPool.QueueUserWorkItem...ThreadPool.QueueUserWorkItem(o => this.DoSomethingLong("参数4")); ThreadPool.QueueUserWorkItem...ThreadPool.QueueUserWorkItem(o => this.DoSomethingLong("参数8")); ThreadPool.QueueUserWorkItem
无参数传递： private void DoWork() { ThreadPool.QueueUserWorkItem(new WaitCallback(this.DoSomeThing)); }...} //有参数传递 private void DoWork() { ThreadPool.QueueUserWorkItem(new WaitCallBack(this.DoSomeThing),...messagebox.show(o.tostring()); } //使用匿名方法更灵活 private void DoWork() { string name="guodiegang"; ThreadPool.QueueUserWorkItem...调用主窗体之后，还希望在调用完后得到一个返回值： private void DoWork() { WaitCallback wc=new WaitCallback(this.DoSomeThing); ThreadPool.QueueUserWorkItem
Generator = new Random(seed); ThreadPool.QueueUserWorkItem...( new WaitCallback(CalBase)); ThreadPool.QueueUserWorkItem(...new WaitCallback(CalFirst)); ThreadPool.QueueUserWorkItem(...new WaitCallback(CalSec)); ThreadPool.QueueUserWorkItem( new
使用线程池开启线程 ThreadPool.QueueUserWorkItem(o=>this.DoSomeThing("btnThreadPool_Click_1"));...ThreadPool.QueueUserWorkItem(o => { this.DoSomeThing("btnThreadPool_Click_2");...之后变为ture，WaitOne就能通过 //如果初始为tue--打开， mre.Rset()之后变为false，WaitOne就只能等待 ThreadPool.QueueUserWorkItem...mres[i] = new ManualResetEvent(false); int k = i; ThreadPool.QueueUserWorkItem
一、异步操作 当我们需要在线程池中加入异步操作时，通过 ThreadPool.QueueUserWorkItem 方法即可实现线程池异步操作。...(Cooking, addVegetables); //服务员错误下单 ThreadPool.QueueUserWorkItem(Cooking);...之后我们在 Main 方法里通过 ThreadPool.QueueUserWorkItem 方法将顾客第一次点餐的内容传入 Cooking 中。...接着我们通过 Sleep 方法来暂停 2 秒，然后我们再次通过 ThreadPool.QueueUserWorkItem 方法将顾客所加的菜传入 Cooking 方法中。...如下代码： ThreadPool.QueueUserWorkItem(state => { int threadId = CurrentThread.ManagedThreadId; string
手动排队任务 [HttpGet("TaskQueue")] public bool TaskQueue() { var inQueues = ThreadPool.QueueUserWorkItem...stateInfo) { Console.WriteLine("此任务来自线程池队列执行"); } 上面的代码中，在 TaskQueue() 内部使用 ThreadPool.QueueUserWorkItem...() 将方法 ThreadProc(Object stateInfo) 压入队列中，并返回一个值：inQueues ，该值指示任务压入队列是否成功，在 .Net Core 中，ThreadPool.QueueUserWorkItem...在排队任务时传递参数 [HttpGet("TaskQueue")] public bool TaskQueue() { var inQueues = ThreadPool.QueueUserWorkItem...(ThreadProc); var inQueuesSecond = ThreadPool.QueueUserWorkItem(ThreadProc, "这是一条测试消息");
Console.ReadLine(); } private static void Pool_Exceute(object obj) { ThreadPool.QueueUserWorkItem
编写代码的过程中经常会遇到需要并行操作的时候，此时就需要使用到多线程操作，.net中提供了多种操作多线程的方法，这里介绍最简单的一种—-通过ThreadPool.QueueUserWorkItem。...首先看实例代码 ThreadPool.QueueUserWorkItem(DoSomeThing); private void DoSomeThing(object state) {...CancellationTokenSource cancelSource = new CancellationTokenSource(); 之后将CancellationTokenSource对象的token通过回调方法传入 ThreadPool.QueueUserWorkItem
InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { ThreadPool.QueueUserWorkItem...InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { ThreadPool.QueueUserWorkItem
显示定义一个取消辅助线程的操作 CancellationTokenSource ctsToken = new CancellationTokenSource(); ThreadPool.QueueUserWorkItem...(o => EoworkOne(ctsToken.Token)); ThreadPool.QueueUserWorkItem(o => EoworkTwo(ctsToken.Token...ThreadPool.QueueUserWorkItem(o => EoworkOne(ctsToken.Token)); ThreadPool.QueueUserWorkItem(o => EoworkTwo...static void Main(string[] args) { ThreadPool.QueueUserWorkItem(o => EoworkOne(CancellationToken.None
下面是几种方式进入线程池： 通过Task Parallel Library（.NET 4.0） 通过调用ThreadPool.QueueUserWorkItem 通过asynchronous delegates...这个Task类在Framework 4.0中有介绍：如果你对老的结构比较熟悉，考虑用非泛型的Task类替换ThreadPool.QueueUserWorkItem，将Asunchoronous delgates...你必须使用老的结构进入线程池： ThreadPool.QueueUserWorkItem和asynchoronous delegates.两者的不同点是asynchronous delegates让你从线程那里返回数据...static void Main(string[] args) { ThreadPool.QueueUserWorkItem(Go); ThreadPool.QueueUserWorkItem(Go...ThreadPool.QueueUserWorkItem没有提供从一个已经完成的线程中得到它的返回值的机制。
("A-4"); } }; foreach (var action in actions) { ThreadPool.QueueUserWorkItem...当然，如果我们用for循环的话，结果就又不一样了 比如写成 for (int i = 0; i < actions.Count; i++) { ThreadPool.QueueUserWorkItem...写成 for (int i = 0; i < actions.Count-1; i++) { ThreadPool.QueueUserWorkItem(state => actions
Main(string[] args) { for (int i = 0; i ThreadPool.QueueUserWorkItem...Program{ static object lockObject = new object(); static void Main(string[] args) { ThreadPool.QueueUserWorkItem...ManualResetEvent manualResetEvent = new ManualResetEvent(false); static void Main(string[] args) { ThreadPool.QueueUserWorkItem
."); ThreadPool.QueueUserWorkItem(ComputeBoundOp, 5); ThreadPool.QueueUserWorkItem
; Thread.Sleep(500); } } static void Main() { // 将任务排队到线程池 ThreadPool.QueueUserWorkItem...(new WaitCallback(ThreadPoolCallback), 1); ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadPoolCallback...), 2); ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadPoolCallback), 3); Console.WriteLine...("Main Thread - Press Enter to exit..."); Console.ReadLine(); }}在这个示例中，我们使用ThreadPool.QueueUserWorkItem
3, 3); //设置最大线程数 for (int i = 0; i < 10; i++) { ThreadPool.QueueUserWorkItem...10; for (int i = 0; i < runningThreads; i++) { ThreadPool.QueueUserWorkItem
使用线程池排队工作项using System;using System.Threading;class Program{ static void Main(string[] args) { ThreadPool.QueueUserWorkItem...AutoResetEvent autoEvent = new AutoResetEvent(false); static void Main(string[] args) { ThreadPool.QueueUserWorkItem...CancellationTokenSource cts = new CancellationTokenSource(); CancellationToken token = cts.Token; ThreadPool.QueueUserWorkItem
