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,但它仍然较慢。
例如,我需要CPU、硬盘和主板信息。
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,但它仍然较慢。
例如,我需要CPU、硬盘和主板信息。
要了解更多详细信息,请参考此链接
以下代码将提供您的CPU ID:
使用System.Management
命名空间
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;
}
要获取硬盘ID和主板ID的详细信息,请参考此链接
为了加快这个过程,请确保不要使用 SELECT *
,而只选择你真正需要的内容。只有在开发阶段尝试找到需要使用的内容时才使用 SELECT *
,因为这样查询将需要更长的时间来完成。
我也曾经寻找同样的内容,不过我找到了另一种解决方案。如果你们感兴趣的话,我可以分享这个类:

的引用。以下的方法受到这个答案对一个相关(更加普遍)问题的启发。
该方法是读取注册表键值 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
中的 MachineGuid
值。此值是在操作系统安装期间生成的。
使用该方法,可以绕过硬件 ID 每台机器的唯一性。其中一种方法是编辑注册表值,但这将导致用户的机器之后出现复杂问题。另一种方法是克隆驱动器映像,这将复制 MachineGuid
值。
然而,没有任何方法是完全防篡改的,但对于普通用户而言,这肯定足够好了。而且,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
)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,我们使用了一个组合: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序列号可能没有填写,或者填写了统一的值:
因此,需要考虑这种情况。
还要记住,ProcessorID
号码在不同的计算机上可能是相同的。
