推荐答案

没有，一个的 GUID 是128位，所以不适合在长，因为这是64位。一个 System.Decimal 是128位，所以给你找很长的路要走，但当然也有它的局限性。即使您保存在柜台一个字符串有其极限。 。计算机alsways有很大的局限性，你必须找到一个这是足够大的，因此您可以持续一段时间。

No, a GUID is 128 bit so won't fit in your long since that is 64 bit. A System.Decimal is 128 bit so will get you a long way, but of course that also has it's limits. Even if you save your counter in a string it has its limits. Computers alsways have limits, you will have to find one which is big enough so you can continue for a while.

编辑：

在.NET 4.0中存在的 BigInteger的可以是相当大的，但要记住，即使是有其局限性，因为它必须适合在内存中。

In .Net 4.0 there is a BigInteger which can be pretty big, but remember, even that has its limits since it has to fit in memory.
