用.net语言写一个获取cpu、主板、硬盘、网卡序列号和mac地址的类

以下是一个使用 .NET 语言（C#）编写的获取计算机硬件信息的类：

using System;
using System.Management;

public class HardwareInfo
{
    public string GetCpuId()
    {
        string cpuId = "";
        ManagementClass mc = new ManagementClass("win32_processor");
        ManagementObjectCollection moc = mc.GetInstances();

        foreach (ManagementObject mo in moc)
        {
            cpuId = mo.Properties["processorID"].Value.ToString();
            break;
        }

        return cpuId;
    }

    public string GetMotherboardId()
    {
        string motherboardId = "";
        ManagementClass mc = new ManagementClass("Win32_BaseBoard");
        ManagementObjectCollection moc = mc.GetInstances();

        foreach (ManagementObject mo in moc)
        {
            motherboardId = mo.Properties["SerialNumber"].Value.ToString();
            break;
        }

        return motherboardId;
    }

    public string GetHardDiskId()
    {
        string hardDiskId = "";
        ManagementClass mc = new ManagementClass("Win32_DiskDrive");
        ManagementObjectCollection moc = mc.GetInstances();

        foreach (ManagementObject mo in moc)
        {
            hardDiskId = (string)mo["SerialNumber"];
            break;
        }

        return hardDiskId;
    }

    public string GetMACAddress()
    {
        string macAddress = "";
        ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection moc = mc.GetInstances();

        foreach (ManagementObject mo in moc)
        {
            if ((bool)mo["IPEnabled"] == true)
            {
                macAddress = mo["MacAddress"].ToString();
                break;
            }
        }

        return macAddress;
    }
}

使用方法：

HardwareInfo hwInfo = new HardwareInfo();
string cpuId = hwInfo.GetCpuId();
string motherboardId = hwInfo.GetMotherboardId();
string hardDiskId = hwInfo.GetHardDiskId();
string macAddress = hwInfo.GetMACAddress();
