c＃：在MergeField Word中插入图像(c# : Insert Image in MergeField Word)

 你没有说明你正在使用哪个反应堆，但是这个页面说ReactorBase是反应堆的基类。 
 
 同样在同一页面上，它提到了一个实例变量的running ， 这里会进一步解释。 
 
 它说 
 
 
 
 running =从启动 期间到关闭 期间为true的bool，其余时间为False。 
 
 
 有了这些信息，我们可以将您的代码更改为： 
 
if reactor.running:
    # do some work

You do not state which reactor you are using, but this page says ReactorBase is the base class for Reactors.
 
Also on the same page, it mentions an instance variable running that is further explained here.
 
It says
 
 
 
running = A bool which is True from during startup to during shutdown and False the rest of the time.
 
 
With that information we can change your code to:
 
if reactor.running:
    # do some work
