最快的方式检索硬盘串行和物理MAC地址
本文关键字：MAC 地址 方式 检索 硬盘 | 更新日期: 2023-09-27 17:52:59
我正在开发一个客户端/服务器应用程序，需要根据硬盘序列号和物理适配器MAC地址为每个注册客户端分配唯一标识符…但我不喜欢使用managentobjectsearcher或任何WMI解决方案，因为它们很慢。如何使用本机方法获得这些值?
如果您想从硬件值中获得唯一标识符，您必须记住，对于每个已注册的客户端始终应用相同的方法非常重要。我的意思是，如果一台机器有多个硬盘(这很常见)，那么您总是需要为每个人从第一个或最后一个硬盘中取出串行。除非您只是出于许可目的而这样做，否则您还必须实现能够理解用户是否更改了其计算机的一个或多个组件的容差算法。我将向您展示我通常用于从硬件值中创建唯一标识符的代码……它可能有点过时，特别是对于64x的支持(注册表项和指针，特别是)，但它只是给你一个想法。指纹仅使用本地方法从第一个HDD串行、第一个适配器MAC地址和SMBIOS数据中创建。
