【中文标题】如何在 C# .NET 中读取 HDD S.M.A.R.T 寄存器并获取该寄存器的所有相关值？【英文标题】：How can I read HDD S.M.A.R.T registers in C# .NET and obtain all the associated values for that register? 【发布时间】：2013-01-19 06:16:52 【问题描述】：如何使用 WMI 或其他方式在 .NET 中读取 HDD 的 SMART 寄存器，从而获得以下数据：
注册名称 当前值 最差价值 阈值 数据（供应商） 智能状态【问题讨论】：
也许***.com/questions/9352017/… 不走运，我已经测试了我在 ***.com 上找到的所有“C# HDD SMART”解决方案。 【参考方案1】：经过一些工作，我整理了代码，使用 C#/WMI 返回了有关 HDD 的所有相关 SMART 信息的综合报告。

我已经建立了一个类库，可以简化查询您需要的所有智能数据。它包括一个演示项目。
GitHub 仓库： Smart.Net Library
用法：
var drives = Simplified.IO.Smart.GetDrives(); // Static Method

请注意，这里不鼓励裸链接到您自己的网站/产品，原因有两个；首先，答案应该作为独立的答案发布，而不仅仅是指向外部站点的链接。其次，自我推销在这里往往不受欢迎，并且经常被标记为垃圾邮件（特别是如果没有披露您链接到自己的网站/产品）。 嗨，安德鲁，我现在才来得及回复。查看***，我看到很多只是链接的答案。在这种情况下，我也做了同样的事情，但没有看到问题。其次，关于您对自我推销的评论；我不关心其他人皱眉的事情。事实是，没有人为我的问题提供解决方案。我花了我的时间和金钱将解决方案放在一起并与全世界分享。像您这样的评论会影响 *** 追随者跟随套件并否决一个好的答案。没有人会赢。 不再链接到博客，相关链接中没有关于此代码的信息。这就是为什么堆栈溢出更喜欢没有一行链接答案的原因。以上是关于如何在 C# .NET 中读取 HDD S.M.A.R.T 寄存器并获取该寄存器的所有相关值？的主要内容，如果未能解决你的问题，请参考以下文章
