如何重新启动“已停止”线？ [英] How to restart "Stopped" thread?

问题描述

我有第二个线程，t2，错误输出并将停止。它的状态是

然后停止。我尝试从线程1，t1开始t2，检查


如果t2.threadstate =" Stopped"那么

t2.start（）


然而，这会引发错误：


System.Threading.ThreadStateException ：线程正在运行或终止;它没有重启。


这个线程如何重启？


另外，我怎么放一个线程在已停止中州？这是通过

thread.abort（）吗？


谢谢，

Brett

解决方案

通常你会启动一个新线程。 thread.abort不允许再次启动

线程。我想如果你做一个thread.suspend你可以

重启它。

如果某个帖子的状态为''已停止''，则该主题要么回复

''中止''请求，要么是终止。创建一个新线程，而不是使用已停止的线程处理

。

此外，如何将线程放入已停止线程中。州？这是通过
thread.abort（）吗？

是的。

我明白了。现在我这样做是为了在Form1

加载时创建新线程：


Public NewThread As New Class1

Public t As System.Threading.Thread = New System.Threading.Thread（New

System.Threading.ThreadStart（AddressOf NewThread.callSomeSub））


发生在外面任何子。我有一个按钮，最初做t.start（）。

一旦线程被停止并且无法重新启动，你说我需要

来创建另一个/新线程。我怎么能在这个

按钮的sub（）中做到这一点？我不能宣布公开因为我会得到：


公共在本地变量声明中无效


我需要新的线程是公共的，所以Form1中的sub（）可以访问它。


谢谢，

Brett

I have a second thread, t2, that errors out and will stop. It''s status is
then "Stopped". I try to start t2 from thread 1, t1, by checking

If t2.threadstate = "Stopped" Then
t2.start()

However, this throws and error:

System.Threading.ThreadStateException: Thread is running or terminated; it
can not restart.

How can this thread restart?

Also, how to I put a thread in a "Stopped" state? Is this through
thread.abort()?

Thanks,
Brett

解决方案

Typically you would start a new thread. thread.abort will not allow that
thread ever to start again. I think if you do a thread.suspend you can
restart it.

If a thread''s state is ''Stopped'', the thread is either responding to an
''Abort'' request or it is terminated. Create a new thread instead of dealing
with the stopped thread.

Yes.

I see. Right now I do this to create the new thread initially when Form1
loads:

Public NewThread As New Class1
Public t As System.Threading.Thread = New System.Threading.Thread(New
System.Threading.ThreadStart(AddressOf NewThread.callSomeSub))

The occurs outside of any sub. I have a button to do t.start() initially.
Once the thread is "stopped" and cannot be restarted, you''re saying I need
to create another/new thread. How can I do that in the sub() of this
button? I can''t declare Public because I''ll get:

Public is not valid on local variable declaration

I need the new thread to be public so sub()s in Form1 can access it.

Thanks,
Brett
