实现效果:

  获取CPU相关信息_get方法

知识运用:

   WMI管理类中的ManagementObjectCollection类  

   ManagementObjectSearcher类的Get方法

   和ManagementObject类

   ManagementObjectCollection类表示通过WMI检索到的管理对象的不同集合

      此集合中的对象为ManagementBaseObject派生类型   包括  ManagementObjectManagementClass

例:通过使用ManagementClass对象的GetInstances方法获取管理对象集合

  ManagementObjectCollection mo = mc.GetInstances();

实现代码:

        private void Form1_Load(object sender, EventArgs e)
        {
            ManagementClass mc = new ManagementClass("Win32_processor");
            ManagementObjectCollection mo = mc.GetInstances();
            foreach (ManagementObject m in mo)
            { 
                textBox1.Text=m["processorid"].ToString();
                //textBox2.Text = m["Manufacturer"].ToString();
                //textBox3.Text = m["Version"].ToString();
                //textBox4.Text = m["Name"].ToString();
            }
            ManagementObjectSearcher mos = new ManagementObjectSearcher("Select * from Win32_processor");
            foreach(ManagementObject m in mos.Get())
            {
                textBox2.Text = m["Manufacturer"].ToString();   //获取CPU制造商名称
                textBox3.Text = m["Version"].ToString();        //获取CPU版本号
                textBox4.Text = m["Name"].ToString();           //获取CPU产品名称
            }
        }
