C#使用ManagementObjectSearcher获取本计算机CPU，硬盘，内存条等相关设备信息

C#获取本操作系统显卡，CPU，硬盘等相关信息，使用ManagementObjectSearcher对象来进行查询。

添加引用程序集框架 System.Management

一、新建窗体应用程序DeviceManagerDemo。重命名Form1为FormDeviceManager。

FormDeviceManager.cs相关源代码如下：

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();
//绑定设备管理器
BindAllComboBox();
//组合框选择索引的改变事件
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);
}

/// <summary>
