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,但仍然很慢。

例如,我需要 CPU、HDD 和主板信息。

有帮助吗?

解决方案

欲了解更多详情,请参阅 这个链接

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 *, ,但只选择您真正需要的。使用 SELECT * 仅在开发过程中,当您尝试找出需要使用的内容时,因为那时查询将需要 很多 需要更长的时间才能完成。

我不会因此获得任何荣誉,因为我发现了它 这里它的效果比我预期的要快。没有显卡、mac 和驱动器 ID,我在大约 2-3 秒内获得了唯一 ID。加上上面的内容,我在大约 4-5 秒内就得到了它。

笔记: 添加参考 System.Management.

下面的方法是由激发此答案以一个相关的(更一般的)问题。

的方法是读取注册表项MachineGuidHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography值。操作系统安装期间产生该值。

有围绕使用这种方法每台机器的硬件ID的唯一性几种方法。一种方法是编辑注册表值,但这之后会导致用户机器上的并发症。另一种方法是克隆这将复制MachineGuid值的驱动图像。

但是,没有一种方法是黑客,防这肯定将是对于普通用户来说足够好。从有利的一面,这种方法是快速的性能,明智和实现简单。

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();
       }
   }
}
