我正在使用C＃进行软件锁定。我需要为每台计算机生成一个唯一的编号。
我已经研究并决定使用CPU编号和硬盘编号作为每台计算机的唯一编号。
我的代码：
private string UniqID()
{
////////////////CpuID
string cpuInfo = string.Empty;
ManagementClass mc = new ManagementClass("win32_processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
cpuInfo = mo.Properties["processorID"].Value.ToString();
break;
}
////////////////HDD ID
string drive = "C";
ManagementObject dsk = new ManagementObject(
@"win32_logicaldisk.deviceid=""" + drive + @":""");
dsk.Get();
string volumeSerial = dsk["VolumeSerialNumber"].ToString();
return volumeSerial + cpuInfo;
}
有效，但有问题！ 当用户重新安装Windows（OS）并想要运行我的软件时，唯一编号已更改。 为什么在再次安装Windows时，唯一编号会发生变化？ CPU编号和HDD编号是否取决于当前的Windows安装？

您实际拥有MotherboardID，CPUID，磁盘串口和MAC地址，根据经验，它们都不是100％。
我们的统计数据显示
0.04％的测试机器没有提供任何信息，我们甚至无法读取计算机名称。也许这些是虚拟PC，HyperV或VMWare实例的某种？
磁盘序列是最可靠的，但很容易更改，mac可以更改，并且如果添加了设备驱动程序（hyperv，wireshark等），则应用的过滤可能会发生变化。
主板和CPUID有时会返回占位符为“无”等的值。
您还应该注意，这些功能调用起来可能非常慢（即使在快速PC上也可能需要几秒钟），因此可能需要尽早在后台线程中将它们踢掉，理想情况下我想阻止他们。
主板ID
private static void FetchMotherboardIdInternal()
{
try
{
ManagementScope scope = new ManagementScope("\\\\" + Environment.MachineName + "\\root\\cimv2");
scope.Connect();
using (ManagementObject wmiClass = new ManagementObject(scope, new ManagementPath("Win32_BaseBoard.Tag=\"Base Board\""), new ObjectGetOptions()))
{
object motherboardIDObj = wmiClass["SerialNumber"];
if (motherboardIDObj != null)
{
string motherboardID = motherboardIDObj.ToString().Trim();
Trace.WriteLine("MotherboardID = " + motherboardID);
if (IsValidMotherBoardID(motherboardID))
{
_motherboardID = motherboardID;
}
}
}
}
catch (System.Threading.ThreadAbortException)
{
throw;
}
catch (Exception ex)
{
Trace.TraceWarning("Failed to read MotherbaordID\r\n" + ex.Message);
}
}
public static bool IsValidMotherBoardID(string value)
{
if (value == null)
return false;
string motherboardID = value.Trim();
return !( motherboardID.Replace(".", "").Replace(" ", "").Replace("\t", "").Trim().Length < 5 ||
motherboardID.ToUpper().Contains("BASE") ||
motherboardID.Contains("2345") ||
motherboardID.ToUpper().StartsWith("TO BE") ||
motherboardID.ToUpper().StartsWith("NONE") ||
motherboardID.ToUpper().StartsWith("N/A") ||
motherboardID.ToUpper().Contains("SERIAL") ||
motherboardID.ToUpper().Contains("OEM") ||
motherboardID.ToUpper().Contains("AAAAA") ||
motherboardID.ToUpper().Contains("ABCDE") ||
motherboardID.ToUpper().Contains("XXXXX") ||
motherboardID.ToUpper().Contains("NOT") ||
motherboardID.ToUpper().StartsWith("00000")
);
}
CPU ID
private static void FetchCpuIdInternal()
{
try
{
using (ManagementClass mc = new ManagementClass("Win32_Processor"))
{
using (ManagementObjectCollection moc = mc.GetInstances())
{
foreach (ManagementObject mo in moc)
{
if (mo.Properties["UniqueId"] != null && mo.Properties["UniqueId"].Value != null)
{
// only return cpuInfo from first CPU
Trace.WriteLine("CPU ID = " + mo.Properties["UniqueId"].Value.ToString());
_cpuID = mo.Properties["UniqueId"].Value.ToString();
}
mo.Dispose();
}
}
}
}
catch (System.Threading.ThreadAbortException)
{
throw;
}
catch (Exception ex)
{
Trace.TraceWarning("Failed to read CPUID\r\n" + ex.Message);
}
}
第一张卡的MAC地址
private static void FecthMACAddressInternal()
{
try
{
using (ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"))
{
using (ManagementObjectCollection moc = mc.GetInstances())
{
if (moc != null)
{
foreach (ManagementObject mo in moc)
{
Trace.WriteLine(mo["Index"] + " Mac " + mo["Caption"] + " : " + mo["MacAddress"] + " Enabled " + (bool)mo["IPEnabled"]);
if (string.IsNullOrEmpty(_macAdderss)) // only return MAC Address from first card
{
if ( mo["MacAddress"] != null && mo["IPEnabled"] != null && (bool)mo["IPEnabled"] == true)
{
_macAdderss = mo["MacAddress"].ToString();
}
}
mo.Dispose();
}
}
}
}
}
catch (System.Threading.ThreadAbortException)
{
throw;
}
catch (Exception ex)
{
Trace.TraceWarning("Failed to read DiskID\r\n" + ex.Message);
}
if (_macAdderss != null)
_macAdderss = _macAdderss.Replace(":", "");
}
驱动器序列号
/// <summary>
/// return Volume Serial Number from hard drive
/// </summary>
/// <param name="strDriveLetter">[optional] Drive letter</param>
/// <returns>[string] VolumeSerialNumber</returns>
public static string GetVolumeSerial(char driveLetter)
{
try
{
using (ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + driveLetter + ":\""))
{
if (disk == null)
return null;
disk.Get();
object diskObj = disk["VolumeSerialNumber"];
if (diskObj != null)
return diskObj.ToString();
}
}
catch (System.Threading.ThreadAbortException)
{
throw;
}
catch (Exception ex)
{
Trace.TraceWarning("Failed to read DiskID\r\n" + ex.Message);
}
try
{
uint serialNum, serialNumLength, flags;
StringBuilder volumename = new StringBuilder(256);
StringBuilder fstype = new StringBuilder(256);
bool ok = GetVolumeInformation(driveLetter.ToString() + ":\\", volumename, (uint)volumename.Capacity - 1, out serialNum, out serialNumLength, out flags, fstype, (uint)fstype.Capacity - 1);
if (ok)
{
return string.Format("{0:X4}{1:X4}", serialNum >> 16, serialNum & 0xFFFF);
}
}
catch (System.Threading.ThreadAbortException)

使用 System.Management ，您可以提取所有硬件信息。有了这个，你可以从这个值创建一个ID，meaby一个加密的id并保存它。
以下是参考：Link
我使用MAC地址，主板ID并且对我很好。
我希望这有帮助！
