如何在C#中快速获取硬件ID？

Question

我需要在我的程序中将许可证与硬件 ID 绑定。我尝试使用 WMI，但仍然很慢。

例如，我需要 CPU、HDD 和主板信息。

Answer 1

有关更多详细信息，请参阅此链接

以下代码将为您提供 CPU ID：

需要命名空间 System.Management

var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");
ManagementObjectCollection mbsList = mbs.Get();
string id = "";
foreach (ManagementObject mo in mbsList)
{
    id = mo["ProcessorId"].ToString();
    break;
}

要加快此过程，请确保不使用 SELECT *，但仅选择您真正需要的内容。仅在开发期间尝试找出需要使用的内容时才使用 SELECT *，因为这样查询将花费更长的时间才能完成。

我不会为此获得任何荣誉，因为我发现了它 此处
它的效果比我预期的要快。没有显卡、mac 和驱动器 ID，我在大约 2-3 秒内获得了唯一 ID。加上上面的内容，我在大约 4-5 秒内就得到了它。

注意：添加对System.Management的引用。

以下方法的灵感来自于一个相关（更一般）问题的此答案。

方法是读取注册表项 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography 中的 MachineGuid 值。该值是在操作系统安装期间生成的。

使用这种方法，有几种方法可以解决每台机器的硬件 ID 的唯一性。一种方法是编辑注册表值，但这会给用户的计算机带来麻烦。另一种方法是克隆驱动器映像，该映像将复制 MachineGuid 值。

然而，没有一种方法是防黑客的，这对于普通用户来说肯定足够好了。从好的方面来说，这种方法性能快速且易于实施。

public string GetMachineGuid()
{
   string location = @"SOFTWARE\Microsoft\Cryptography";
   string name = "MachineGuid";

   using (RegistryKey localMachineX64View = 
       RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
   {
       using (RegistryKey rk = localMachineX64View.OpenSubKey(location))
       {
           if (rk == null)
               throw new KeyNotFoundException(
                   string.Format("Key Not Found: {0}", location));

           object machineGuid = rk.GetValue(name);
           if (machineGuid == null)
               throw new IndexOutOfRangeException(
                   string.Format("Index Not Found: {0}", name));

           return machineGuid.ToString();
       }
   }
}

Answer 5

我们使用来自 Win32_processor 的处理器 ID 号 (ProcessorID) 和来自 Win32_ComputerSystemProduct 的通用唯一标识符 (UUID) code>：

ManagementObjectCollection mbsList = null;
ManagementObjectSearcher mos = new ManagementObjectSearcher("Select ProcessorID From Win32_processor");
mbsList = mos.Get();
string processorId = string.Empty;
foreach (ManagementBaseObject mo in mbsList)
{
    processorId = mo["ProcessorID"] as string;
}

mos = new ManagementObjectSearcher("SELECT UUID FROM Win32_ComputerSystemProduct");
mbsList = mos.Get();
string systemId = string.Empty;
foreach (ManagementBaseObject mo in mbsList)
{
    systemId = mo["UUID"] as string;
}

var compIdStr = $"{processorId}{systemId}";

以前，我们使用了组合：处理器 ID ("Select ProcessorID From Win32_processor") 和主板序列号 ("SELECT SerialNumber FROM Win32_BaseBoard")，但后来我们发现主板的序列号可能没有填写，也可能填写统一的值：

• 由OEM填写
• None
• 默认字符串

因此，这种情况值得考虑。

另请记住，ProcessorID 编号在不同计算机上可能相同。
