c# 获取电脑硬件信息通用查询类[测试通过]

C#获取电脑硬件信息通用类[Computer]代码展示和分析，简介如下：

1.项目中添加System.Management引用。

2.添加类Computer，把下面代码全选，复制，粘贴。

3.使用方法new Computer().GetComputerName()。

代码

using System;
using System.Management;  // 添加System.Management引用

public class Computer

    public string CpuID;
    public string MacAddress;
    public string DiskID;
    public string IpAddress;
