如何使用resume（）回调挂起的线程 [英] How to call back the thread which is suspended using resume()

问题描述

如何使用resume（）执行剩余的迭代？

How to use resume()to execute remaining iterations?

namespace CAthreads
{

    class clsthread2
    {
        public void thread1()
        {
            for (int i = 0; i < 10; i++)
            {

                Thread t1 = Thread.CurrentThread;
             Console.WriteLine(t1.Name + "=" + i);
                if (i == 5)
                {
                 Console.WriteLine(t1.Name + " is going to suspend");
                 t1.Suspend();
                  
                }
            }
        }

               class Class1
        {
            static void Main()
            {
                clsthread2 obj1 = new clsthread2();
                ThreadStart tstart1 = new ThreadStart(obj1.thread1);
                ThreadStart tstart2 = new ThreadStart(obj1.thread1);
                Thread thr1 = new Thread(tstart1);
                Thread thr2 = new Thread(tstart1);
                thr1.Name = "NTR";
                thr2.Name = "ANR";
                thr1.Start();
                thr2.Start();
              Console.Read();
            }
        }
    }

推荐答案

对于初学者来说，暂停和恢复是过时的，并且根据到MSDN：将在未来版本中删除。 （ http://msdn.microsoft.com/en-us/library/ tttdef8x（v = vs.110）.aspx [ ^ ]）



这意味着您不应该使用它们，因为它们明天可能无法使用！

你应该使用 WaitHandles [< a href =http://msdn.microsoft.com/en-us/library/ms228964(v=vs.110).aspx\"target =_ blanktitle =New Window> ^ ] - 它们更灵活，不会过时...



尝试 WaitOne [ ^ ] - 它包含一个示例。

For starters, Suspend and Resume are obsolete, and according to MSDN: "will be removed in a future release." (http://msdn.microsoft.com/en-us/library/tttdef8x(v=vs.110).aspx[^])

This means you should not be using them, as they may not work tomorrow!
You should be using WaitHandles[^] instead - they are much more flexible and not obsolete...

Try WaitOne[^] - it includes an example.

如果你想将线程恢复到其他类，那么这将是hel你...



我已更新你的代码....

If you wanted to Resume thread into other class then this will help you...

I have updated your code....

namespace CAthreads
{

    class clsthread2
    {
        Thread t1;
        public void thread1()
        {
            for (int i = 0; i < 10; i++)
            {

                t1 = Thread.CurrentThread;
                Console.WriteLine(t1.Name + "=" + i);
                if (i == 5)
                {
                    Console.WriteLine(t1.Name + " is going to suspend");
                    t1.Suspend();

                }
            }
        }

       // Created new method to resume thread...
        public void ResumeThread()
        {
            if (t1.ThreadState == ThreadState.Suspended)
            {
                t1.Resume();
            }
        }
    }

    class Class1
    {
        static void Main()
        {
            clsthread2 obj1 = new clsthread2();
            obj1.ResumeThread();   //Method of Class clsthread2
            
            ThreadStart tstart1 = new ThreadStart(obj1.thread1);
            ThreadStart tstart2 = new ThreadStart(obj1.thread1);
            Thread thr1 = new Thread(tstart1);
            Thread thr2 = new Thread(tstart1);
            thr1.Name = "NTR";
            thr2.Name = "ANR";
            thr1.Start();
            thr2.Start();
            Console.Read();
        }
    }
}
