可能重複:
Is there any difference between a GUID and a UUID?GUID和UUID有什麼區別?
請告訴我一個GUID和UUID,和我應該用真正的獨特性之間的區別?
更新: 我需要爲唯一太算法我選擇什麼東西?
1) MAC address of network card
2) 128 bits (isn't 64 bits enough?)
3) What if I have a multicore machine on the same MAC address. Isn't there a chance of duplicates?
請問您的網站上創建64位或128位的GUID? – Zubair 2010-02-17 13:59:50
它使用Guid.NewGuid所以這是128位GUIDS! http://msdn.microsoft.com/en-us/library/system.guid.aspx – 2010-02-17 14:07:13
