我需要在我的程序中将许可证绑定到硬件 ID。我尝试使用 WMI,但它仍然很慢。
例如,我需要 CPU、HDD 和主板信息。
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,请确保您不使用SELECT *
,而只选择您真正需要的。SELECT *
仅在开发期间尝试找出需要使用的内容时使用,因为这样查询将花费更长的时间才能完成。
我来到这里寻找同样的东西,我找到了另一个解决方案。如果你们有兴趣,我分享这个课程:

我不会为此获得任何功劳,因为我在这里找到了它。 它的工作速度比我预期的要快。在没有显卡、mac 和驱动器 ID 的情况下,我在大约 2-3 秒内获得了唯一 ID。包括上面的那些,我在大约 4-5 秒内得到了它。
注意:添加对System.Management
.
以下方法的灵感来自这个对相关(更一般)问题的回答。
方法是读取MachineGuid
注册表项中的值HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
。该值是在操作系统安装期间生成的。
使用这种方法来解决每台机器的硬件 ID 唯一性的方法很少。一种方法是编辑注册表值,但这会导致用户机器出现问题。另一种方法是克隆将复制该MachineGuid
值的驱动器映像。
但是,没有任何方法是防黑客的,这对于普通用户来说肯定已经足够了。从好的方面来说,这种方法在性能方面快速且易于实施。
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();
}
}
}
我们使用来自 的处理器 ID 号 ( ProcessorID
) 和来自Win32_processor
的通用唯一标识符 ( UUID
) 的组合Win32_ComputerSystemProduct
:
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}";
之前我们用了一个组合:处理器ID "Select ProcessorID From Win32_processor"
("SELECT SerialNumber FROM Win32_BaseBoard"
因此,这种情况值得考虑。
还要记住,ProcessorID
不同计算机上的数字可能相同。
