如果我通过ParameterizedThreadStart将对象传递给线程,我可以稍后访问它吗?

如果我以以下方式开始一个线程

Thread newThread = new Thread(new ParameterizedThreadStart(MyThreadMethod));
Object myObject = new Object();
newThread.Start(myObject);

在myObject完成任务后,我可以找出它对myObject做了什么吗?

// at some point later
if(newThread.ThreadState == ThreadState.Stopped)
{
//access my object? how?
}
