如何在C#中快速获取Hardware-ID？

Question

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.

Answer 1

以下代码将为您提供CPU ID:

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 *,但只选择您真正需要的.使用SELECT *时,你试图找出你所需要的使用,因为那么查询将在开发过程中只多的时间才能完成.

我不会因此而受到任何赞扬,因为我在这里找到了 它比我预期的更快.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.随着上面的那些我在大约4-5秒内得到它.

Answer 3

以下方法的灵感来自对相关(更一般)问题的答案.

方法是读取MachineGuid注册表项中的值HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography.在OS安装期间生成此值.

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.另一种方法是克隆将复制MachineGuid值的驱动器映像.

但是,没有一种方法是防黑客的,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();
       }
   }
}
