推荐答案
首先，请点击上方的改进问题".不，您不必进行任何改进，只需查看HTML源代码即可了解应如何以HTML格式格式化C#源代码，以便在CodeProject帖子中看起来可读—我已将您的帖子稍作修正.
现在，从以下更改开始:代替此:
First, please click "Improve question" above. No, you don''t have to improve anything, just look at the source HTML code to see how the C# source code should be formatted in HTML to look readable in the CodeProject post — I fixed your post just a bit.
Now, start with the following change: instead of this:
catch (Exception e)
{
Console.WriteLine("Invalid!");
}
至少写这样的东西:
write something like this, as a bare minimum:
catch (Exception e)
{
Console.WriteLine(@"{0}: ""{1}""", e.GetType().FullName, e.Message);
}
您将学到更多有关您的问题的信息.
如果这还不够，请添加到输出e.Stack和e.InnerException，提供所有内部异常的递归输出.
现在，正确放置该try-catch块.在每个线程堆栈的最顶部执行此操作.将启动线程顶部的一个块放在一个Main方法周围，将另一个try-catch块放在StartGame的最顶部附近.
这足以了解您的异常情况.无论如何，您是什么意思未处理的异常"?处理吗?
您真的需要做所有这些吗?如果仅使用调试器并找出问题，则不会.如果您自己无法解决问题，则此异常内容将帮助您改善问题:使用改善问题"添加异常转储；并指出源代码中if所在的源代码行.
是的，任何人都可以构建和运行您的代码，但是，如果您付出一点努力，您将有更多的变化来获得有效的帮助.另外，这种经验将在将来为您提供帮助.
祝你好运，
and you will learn a lot more about your problem.
If this is not enough, add to output e.Stack and e.InnerException, provide recursive output of all inner exceptions.
Now, place this try-catch block properly. Do it on the very top of the stack of each thread. Put one block of the top of starting thread, around just one Main method, another try-catch block — around the very top of StartGame.
That would be enough to learn all about your exception. Anyway, what do you mean "unhandled exception"? Handle it?
Do you really need to do all that? Not if you simply use debugger and find out the problem. If you fail to solve the problem yourself, this exception stuff will help you to improve your question: use "Improve question" to add exception dump; and indicate the source line where if goes in your source code.
Yes, anyone can build and run your code, but you have much more change to get effective help if you do this little effort. Also, this experience will help you in future.
Good luck,
