推荐答案

我也有这个想法，我认为其中一些集合存在错误.我第一次尝试进行查找时遇到了一个错误，但此后一切都很好，所以我添加了一个try/catch来进行无意义的查找，有时会崩溃，但随后我的代码运行正常.如果这对您不起作用，则可以尝试发布实际的错误消息和代码.

I''ve had this too, I think there''s a bug in some of the collections. I had a bug the first time I tried to do a lookup, but afterwards it was fine, so I added a try/catch that did a meaningless lookup, and it sometimes blows up, but then my code runs fine. If that doesn''t work for you, you could try posting the actual error message, and the code.
