C# 获取本机CPU序列号，MAC地址，硬盘ID，本机IP地址，计算机名，物理内存，PC类型

首先添加引用 System.Management

using System;
using System.Management;

public class Computer
{
    public static string CpuID; //1.cpu序列号
    public static string MacAddress; //2.mac序列号
    public static string DiskID; //3.硬盘id
    public static string IpAddress; //4.ip地址
    public static string LoginUserName; //5.登录用户名
    public static string ComputerName; //6.计算机名
    public static string SystemType; //7.系统类型
    public static string TotalPhysicalMemory; //8.内存量 单位：M

    static Computer()
    {
        CpuID = GetCpuID();
