c#获取本机电脑相关信息

建立一个类.然后读取信息.调用代码如下.
HardInfoClass myclass=new HardInfoClass();
textBox1.Text=myclass.GetHardDiskID();
textBox2.Text=myclass.GetCpuID();
textBox3.Text=myclass.GetNetCardMAC();
textBox4.Text=myclass.GetNetCardIP();
textBox5.Text=myclass.GetHostName();
textBox6.Text=myclass.GetVolOf("D");//C盘58c6b679跟D盘6ed62864不一样

//textBox7.Text=myclass.GetHashCode();
//textBox8.Text=myclass.GetCpuID();

类HardInfoClass代码如下

using System;
using System.Net;
using System.Runtime.InteropServices;
using System.Management; //需要在解决方案中引用System.Management.DLL文件

namespace FileTransLate.PCStatus
