[转]C#精髓第二讲 WMI完美秀出CPU编号厂商主频电压等全部信息

本文的例子在以下环境调试通过：Windows2003+AMD64双核CPU+VisualStudio2005(C#)下调试通过，无错版！

首先要添加“引用”一个dll，选择“System Management”；

再引入2个命名空间：
using System.Management;
using System.IO;

代码：
Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Management;
using System.IO;
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //获取CPU编号
            ManagementClass MyClass = new ManagementClass("Win32_Processor");
            ManagementObjectCollection MyCollection = MyClass.GetInstances();
            String MyInfo = "当前系统CPU编号是：";
            string MyCPUID = "";
            foreach (ManagementObject MyObject in MyCollection)
            {
                MyCPUID = MyObject.Properties["ProcessorId"].Value.ToString();
                break;
            }
            MyInfo += MyCPUID;
            MessageBox.Show(MyInfo, "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }

        private void button2_Click(object sender, EventArgs e)
        {

            String MyInfo = "计算机CPU的当前电压是：";
            ManagementObjectSearcher MySearcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
            foreach (ManagementObject MyObject in MySearcher.Get())
