我想工作，通过对问题的 projecteuler.net ，但我一直运行到几个问题。

I'm trying to work through the problems on projecteuler.net but I keep running into a couple of problems.

首先是存储在名单，其中元素的大quanities的问题; T＆GT; 。我一直在列表中存储大量时获得OutOfMemoryException异常的。

The first is a question of storing large quanities of elements in a List<t>. I keep getting OutOfMemoryException's when storing large quantities in the list.

现在我承认我可能不会做这些事情的最佳途径，但是，有没有定义的一些方法的应用程序可以有多少内存占用？

Now I admit I might not be doing these things in the best way but, is there some way of defining how much memory the app can consume?

它通常会崩溃，当我得到关于云燕亿元素：•

It usually crashes when I get abour 100,000,000 elements :S

其次，一些问题需要添加大量的数字。我用，我觉得数字是会得到超级大ULONG数据类型，但我还是设法换过去最大的支持int和进入负数。

Secondly, some of the questions require the addition of massive numbers. I use ulong data type where I think the number is going to get super big, but I still manage to wrap past the largest supported int and get into negative numbers.

你有什么秘诀与令人难以置信的大量的工作？

Do you have any tips for working with incredibly large numbers?

推荐答案

您需要使用使用一些基本的数学校长分裂这些操作了一大批类。这实现对codePoject一个C＃的BigInteger库似乎是最有前途的。文章与庞大的数字是如何工作的操作的一些很好的解释，也是如此。

You need to use a large number class that uses some basic math principals to split these operations up. This implementation of a C# BigInteger library on CodePoject seems to be the most promising. The article has some good explanations of how operations with massive numbers work, as well.
