C#获取cpuid问题

Question

string GetCpuID()
        {
            try
            {
                //获取CPU序列号代码 
                string cpuInfo = "";//cpu序列号 
                ManagementClass mc = new ManagementClass("Win32_Processor");
                ManagementObjectCollection moc = mc.GetInstances();
                foreach (ManagementObject mo in moc)
                {
                    cpuInfo = mo.Properties.Value.ToString();
                }
                moc = null;
                mc = null;
                return cpuInfo;
            }
            catch
            {
                return "unknow";
            }
        }

已引用命名空间using System.Management;

Answer 1

需要在“引用”中引入 System.Management 库 （DLL）

Answer 2

看看这段代码是否符合需要：

ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
    cpu_info = mo.Properties["ProcessorId"].Value.ToString();
    break;
}
