Debug.WriteLine很难

本文介绍了Debug.WriteLine很难的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我发现了一个奇怪的问题，关于Debug.WriteLine和Thread在 暂停状态。 创建一个线程，启动它并使其暂停。 然后尝试Debug.WriteLine - 它将启动100％CPU使用率而不阻塞 主线程。 /> 代码如下（用两个按钮创建一个）。 步骤： 点击button1（启动并暂停线程）。然后点击button2。 你会注意到CPU的使用情况。天空。 只有当线程被暂停时才会出现这种情况。 Miha private void button1_Click（object sender，System.EventArgs e） { t = new Thread（新的ThreadStart（新的Tubo（）。执行））; t.Name =" Tubo"; t.Start（）; } private void button2_Click（object sender，System.EventArgs e） { //Debug.WriteLine（t.ThreadState）; Debug.WriteLine（"吐蕃）; } } 公共课吐蕃 { public void执行（） { 而（真） { Thread.CurrentThread.Suspend（）; } } }

Hi, I''ve found a strange problem regarding Debug.WriteLine and Thread in suspended state. Create a thread, start it and make it suspended. Then try Debug.WriteLine - it will start 100% CPU usage while not blocking the main thread. Code is below (create a from with two buttons). Steps: Click on button1 (starts and suspends the thread). Then click on button2. You''ll note the CPU usage goes to sky. This only occurs if the thread is suspended. Miha private void button1_Click(object sender, System.EventArgs e) { t = new Thread(new ThreadStart(new Tubo().Execute)); t.Name = "Tubo"; t.Start(); } private void button2_Click(object sender, System.EventArgs e) { //Debug.WriteLine(t.ThreadState); Debug.WriteLine("Tubo"); } } public class Tubo { public void Execute() { while( true) { Thread.CurrentThread.Suspend(); } } }

推荐答案

不要使用Suspend（），使用同步机制。 Suspend（）是问题，而不是Debug.WriteLine（），也许其他人可以 解释原因...... Don''t use Suspend(), use synchronization mechanisms. Suspend() is the problem, not Debug.WriteLine(), and maybe someone else can explain why...

不是。 CLR只会在他认为线程安全时暂停该线程这样做（参见MSDN中Thread.Suspend的描述）。 在您的代码中....看起来CLR认为挂起线程是不安全的，所以你无限期地循环消耗所有CPU 资源...... 而（true） { Thread.CurrentThread.Suspend（ ）; } 威利。 Miha Markic < MS ** @ spin.si>在留言新闻中写道：％2 ****************** @ TK2MSFTNGP11.phx.gbl ... No it is not. The CLR will only suspend the thread when HE considers it is safe to do so (see description of Thread.Suspend in MSDN). In your code.... it looks like the CLR considers it is not safe to suspend the thread so you loop indefinitely consuming all CPU resources... while( true) { Thread.CurrentThread.Suspend(); } Willy.
