请问 GUID 是如何分类的

Question

如题

Answer 1

楼主是不是说的CLSID、IID、DIID之类的？

Answer 2

微软老大能用些特定的GUID,那些数字看起来比较顺眼那种我们一般用Guid 生成器 生成一个,不然重复了也不好

Answer 3

那一个设备的GUID是怎么产生的！！
事先一定是有定义的吧

Answer 4

这个东西是平坦式的，没有类别。以为你可以把它看作就是一个 128 位的数字，数字怎么分类？当然你可以发明你自己的类别，比如第一个数字必须是 F 的 GUID 为一类。

Answer 5

我列了一些出来想看看系统是怎么分的,有没有什么规律？可是看不出来呀。

Answer 6

这当然没有规律了。这里面 GUID 只是个没有意义的数据，放到了对应的类别下了，光把这些 GUID 列出来，你是没有办法搞明白他们原本该在什么类别底下的。打个比方吧，给你各个班级的花名册，你就能知道哪个学生在哪个班级，所有学生在操场上活动，你就没法区分。
