C#:异常后停止线程 [英] C#: Stopping a thread after an Exception
本文介绍了C#:异常后停止线程的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这样的代码:
Thread t = new Thread(() => UpdateImage(origin));
t.Name = "UpdateImageThread";
t.Start();
如果方法UpdateImage(来源)抛出一个异常,就必须停止线或将被采空异常后?
If method UpdateImage(origin) throw an exception, it is necessary to stop thread or it will be stoped after the exception?
感谢您!
推荐答案
如果 UpdateImage
抛出一个异常,它可能会记下你的整个过程。这又引出一个顶级的异常任何线索表明一个大问题。你应该把尝试
/ 抓
围绕 UpdateImage $ C把这个包,例如$ C>和做适当的事情。是的,如果异常到达一个线程的顶部,线程是死的:
If UpdateImage
throws an exception, it is probably going to take down your whole process. Any thread that raises a top-level exception indicates a big problem. You should wrap this, for example by putting try
/catch
around UpdateImage
and doing something suitable. And yes, if an exception gets to the top of a thread, the thread is dead:
Thread t = new Thread(() => {
try {UpdateImage(origin); }
catch (Exception ex) {Trace.WriteLine(ex);}
});
t.Name = "UpdateImageThread";
t.Start();
(或您的错误处理的选择)
(or your choice of error handling)
