如何在.NET中生成版本1 Guid? [英] How to generate a version 1 Guid in .NET?

问题描述

据我了解，在Windows 2000或附近版本中，依赖时间戳和MAC地址的版本1指南已由版本4取代-更加随机.

As I understand it, Version 1 Guids that relied on timestamps and MAC address, were replaced by Version 4 - more random - in Windows 2000 or thereabouts.

如果我更喜欢从版本4开始，从.Net生成版本1 guid的最简单方法是什么?

What's the easiest way to generate a Version 1 guid from .Net, if I prefer it to a version 4?

(我要做希望时间戳和(几乎)唯一的机器ID可提取.我确实控制了整个环境-我可以接受隐私保护/绝对随机性的任何损失)

(I do want the timestamp and (almost) unique machine id to be extractable. I do control the entire environment - I'm ok with privacy/any loss of absolute randomness)

谢谢.

推荐答案

P/调用 UuidCreateSequential -它返回1类导航:

P/Invoke UuidCreateSequential - it returns type 1 guids:

出于安全原因，已修改UuidCreate，使其不再使用计算机的MAC地址生成UUID.引入UuidCreateSequential允许使用机器的以太网卡的MAC地址创建UUID.

For security reasons, UuidCreate was modified so that it no longer uses a machine's MAC address to generate UUIDs. UuidCreateSequential was introduced to allow creation of UUIDs using the MAC address of a machine's Ethernet card.
