C#使用ManagementObjectSearcher獲取本計算機CPU，硬碟，記憶體條等相關裝置資訊

C#獲取本作業系統顯示卡，CPU，硬碟等相關資訊，使用ManagementObjectSearcher物件來進行查詢。

新增 引用 程式集 框架 System.Management

一、新建窗體應用程式DeviceManagerDemo。重新命名Form1為FormDeviceManager。

FormDeviceManager.cs相關原始碼如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Management;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace DeviceManagerDemo
{
    public partial class FormDeviceManager : Form
    {
        public FormDeviceManager()
        {
            InitializeComponent();
            //繫結裝置管理器
            BindAllComboBox();
            //組合框選擇索引的改變事件
            cboHardware.SelectedIndexChanged += ComboBox_SelectedIndexChanged;
            cboOperatingSystem.SelectedIndexChanged += ComboBox_SelectedIndexChanged;
        }

        private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
        {
            ComboBox cbo = sender as ComboBox;
            if (cbo == null || cbo.SelectedIndex < 0) 
            {
                return;
            }
            string queryKey = cbo.SelectedValue as string;
            DisplayDeviceMessage(queryKey);      
        }
