输出:hreadState: Unstarted, ApartmentState: MTA

ThreadState: Running, ApartmentState: MTA

ThreadStateException caught:
Thread is not in the Unstarted or Running state.
ThreadState: WaitSleepJoin, ApartmentState: MTA

问题: 为什么最后的时候newthread的状态为 WaitSleepJoin?

如果 我使用

newthread.resume()
程序提示:“线程不是用户挂起的;无法使其继续。”

但是我新创建另外一个线程,也是如此提示。

是不是WaitSleepJoin以后就不能再使用该线程了啊?

WaitSleepJoin
應該是必須等到指定時間過後吧,不過可以abort supend 好像

resume之前必須先supend 否則會出現上面的錯誤

try
{
// This causes an exception since newThread is sleeping.
newThread.SetApartmentState(ApartmentState.STA);
********************************************
是不是因为这个语句设置本该在线程启动之前就应该设置好的属性所以导致异常。
但是为什么会使该线程状态变为waitsleepjoin()呢?
*******************************************
}
catch (ThreadStateException stateException)
{
Console.WriteLine("\n{0} caught:\n" +
"Thread is not in the Unstarted or Running state.",
stateException.GetType().Name);
Console.WriteLine("ThreadState: {0}, ApartmentState: {1}",
newThread.ThreadState, newThread.GetApartmentState());
}

catch (ThreadStateException stateException)
{
Console.WriteLine("\n{0} caught:\n" +
"Thread is not in the Unstarted or Running state.",
stateException.GetType().Name);
***************************
newThread.Suspend();
newThread.Resume();
加上这两句就出错。
“线程目前未运行;无法使其挂起。”
***************************
Console.WriteLine("ThreadState: {0}, ApartmentState: {1}",
newThread.ThreadState, newThread.GetApartmentState());
}

catch出錯後
newThread是被強制關了吧?

你sleep了 所以是waitsleepjoin
