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);
}
