Question

I have this code:

Thread t = new Thread(() => UpdateImage(origin));
t.Name = "UpdateImageThread";
t.Start();

If method UpdateImage(origin) throw an exception, it is necessary to stop thread or it will be stoped after the exception?

Thank you!

Answer 1

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();

(or your choice of error handling)
