我们不做你的作业：它是为...一个原因。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但我们不打算为你做这一切！



但基本上，没有办法做到这一点，不涉及某种形式的循环 - 它可能是显式的，如 或 foreach ，或者它可以像Linq查询或SQL一样隐藏。



我？我会对记录进行排序并查找彼此相邻的重复值...使用循环。

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

But basically, there is no way of doing this that doesn't involve a loop of some form - it may be explicit, like for or foreach, or it could be "hidden" like a Linq query or SQL.

Me? I'd sort the records and look for duplicate values next to each other...using a loop.
