我需要在我的程序中将许可证绑定到硬件ID。我尝试过使用WMI,但它仍然很慢。
我需要,例如,CPU,HDD和主板信息。

有关详细信息,请参阅this link
以下代码将为您提供CPU ID:
名称空间需要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;
}
有关硬盘ID和主板ID详情,请参阅this-link
要加快此过程,请确保您不使用SELECT *
,而只选择您真正需要的内容。仅在开发期间使用SELECT *
,当您尝试找出需要使用的内容时,因为查询将花费多更长时间才能完成。

我不会因此而受到任何赞扬,因为我找到了它here 它的工作速度比我预期的要快。没有图形卡,mac和驱动器ID,我在大约2-3秒内获得了唯一的ID。有了上面的那些,我在大约4-5秒内得到它。

以下方法受到this answer的启发,涉及相关(更一般)的问题。
方法是读取注册表项MachineGuid
中的HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
值。该值在OS安装期间生成。
使用这种方法,每台机器的硬件ID的唯一性几乎没有办法。一种方法是编辑注册表值,但这会导致用户机器出现并发症。另一种方法是克隆驱动器映像,该映像将复制MachineGuid
值。
但是,没有一种方法可以防止黑客攻击,这对于普通用户来说肯定是足够好的。从好的方面来说,这种方法在性能上快速且易于实现。
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();
}
}
}

我们使用了ProcessorID
中的处理器ID号(Win32_processor
)和UUID
中的通用唯一标识符(Win32_ComputerSystemProduct
)的组合:
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,我们使用了以下组合:处理器ID("Select ProcessorID From Win32_processor"
)和主板序列号("SELECT SerialNumber FROM Win32_BaseBoard"
),但随后发现主板序列号可能没有填写,或者可以用统一的值填充
因此,值得考虑这种情况。
还请记住,ProcessorID
号在不同的计算机上可能是相同的。
