线程未关闭或终止 [英] Thread not closing or terminating

问题描述

这是一个多线程简单控制台程序，我想在按字符"t"时启动一个线程，并在按字符"x"时关闭它.以下是代码，但是当我第一次按"t"键时，它也开始按"x"键关闭，但是当我第二次尝试按"t"键时，它卡住了.

This is a multi thread simple console program , i want to start one thread on pressing the character "t" and close it on pressing the character "x". the following is the code but when i press "t" for the first time its started and close on pressing "x" as well but when i tried to press "t" for the second time its stuck.

            Thread t2 = new Thread(staric2); // this is staric 2 in diffrent position<br />

推荐答案

使用t1.Join，t2.Join而不是Suspend.

当您告诉Join时，它将阻塞所有操作，直到线程完成.

祝您好运

Use t1.Join, t2.Join rather then Suspend.

When you you tell Join, it blocks everything until the thread is done.

Good luck

您的逻辑错误(每个while周期将Time设置为1).
:)

Your logic is wrong (Time is set to 1 at every while cycle).
