2019年的时候用PowerBuilder写过一个计算机信息收集小程序，《计算机信息收集小程序》，当时是查注册表来实现的。
还可以通过对windows的API调用来做，这个稍微有点麻烦。
使用C#也可以通过三种方式来实现，分别是读取注册表、windows的API调用、读取设备数据库，其中读取设备数据库比较方便快捷。
这个星期居家办公很不方便，打算就用C#来写这个小程序。
完成了硬件参数、操作系统、网络信息、软件以及安全信息的读取，后面就可以存入数据库方便网络上的调取和查询。
思路：
1、System.Management命名空间来获取对设备参数的提取；
2、建立对象并设置好属性字段，逐个赋予对象属性字段的值；
3、将对象序列化；
4、反序列化读取对象的字段属性值，放入字典中；
5、根据属性名逐一读取硬件参数。
下面是读取硬件参数的代码：
public class OSInformation
{
public string OSName { get; set; }
public string OSType { get; set; }
public string OSSerialNumber { get; set; }
public string ComputerName { get; set; }
public string LogonUserName { get; set; }
}
public class HInformaiton
{
public string MainboardName { get; set; }
public string MemorySize { get; set; }
public string HarddiskSize { get; set; }
public string VideocardName { get; set; }
public string SoundcardName { get; set; }
public string NetworkcardName { get; set; }
public string ManufacturerName { get; set; }
public string ManufactureDate { get; set; }
}
public class SInformation
{
public string VRV { get; set; }
public string QAX { get; set; }
public string WPS { get; set; }
}
public class WInformation
{
public string IP { get; set; }
public string Subnetmask { get; set; }
public string Gateway { get; set; }
}

public static string GetJsonStr()
{
string ReturnStrJson = "";
var HInfor = new HInformaiton { MainboardName ="未知", MemorySize = "未知", HarddiskSize = "未知", VideocardName = "未知", SoundcardName = "未知", NetworkcardName = "未知",ManufacturerName= "未知", ManufactureDate= "未知" };
//主板信息
try {
ManagementObjectSearcher myMainboard = new ManagementObjectSearcher("SELECT * FROM Win32_BaseBoard");
foreach (ManagementObject board in myMainboard.Get())
{
HInfor.MainboardName = board["Product"].ToString();
//break;
}
}
catch (Exception ex) {
HInfor.MainboardName = "未知";
}
//内存信息
try {
ManagementObjectSearcher myMemory = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMemory");
//定义内存总大小变量
double MemorySize = 0;
foreach (ManagementObject obj in myMemory.Get())
{
//将内存大小换算成G单位
MemorySize += Convert.ToDouble(obj["Capacity"]) / 1024 / 1024 / 1024;
}
HInfor.MemorySize = MemorySize.ToString()+"G";
} catch (ManagementException e) {
HInfor.MemorySize = "未知";
}
//硬盘信息
try {
//获取本机所有硬盘信息
ManagementObjectSearcher myHarddisk = new ManagementObjectSearcher("select * from Win32_DiskDrive");
foreach (ManagementObject drive in myHarddisk.Get())
{
//获取硬盘容量
var capacity = (Convert.ToDouble(drive["Size"]) / 1024 / 1024 / 1024).ToString("0.00") + "G";
//获取硬盘类型
var mediaType = drive["MediaType"];
HInfor.HarddiskSize = capacity.ToString() + "|" + mediaType.ToString();
}
}
catch (Exception ex) {
HInfor.HarddiskSize = "未知";
}
//显卡信息
try {
ManagementObjectSearcher myVideoObject = new ManagementObjectSearcher("select * from Win32_VideoController");
foreach (ManagementObject obj in myVideoObject.Get())
{
HInfor.VideocardName = obj["Name"].ToString();
}
} catch (ManagementException e) {
//e.Message
HInfor.VideocardName = "未知";
}
//声卡信息
try {
// 创建WMI搜索对象
ManagementObjectSearcher mySoundcard = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_SoundDevice");
// 遍历搜索结果
foreach (ManagementObject mo in mySoundcard.Get())
{
// 获取声卡名称
HInfor.SoundcardName = mo.GetPropertyValue("Name").ToString();
}
} catch (ManagementException e) {
HInfor.SoundcardName = "未知";
}
//网卡信息（Mac地址）
try {
// 获取本地网络接口信息
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in nics)
{
// 如果是RJ45网卡
if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
{
string S1 = (string)adapter.Description;
if (S1.Contains("PCI")){
HInfor.NetworkcardName = S1;
}
}
}
}
catch (ManagementException e) {
HInfor.NetworkcardName = "未知";
}
//获取生产商和生产日期
try
{
//获取生产商
ManagementObjectSearcher ManufacturerInfo = new ManagementObjectSearcher("select * from Win32_ComputerSystem");
foreach (ManagementObject obj in ManufacturerInfo.Get())
{
HInfor.ManufacturerName = obj["Manufacturer"].ToString();
}
//获取生产日期
ConnectionOptions options = new ConnectionOptions();
ManagementScope scope = new ManagementScope("\\\\.\\root\\cimv2", options);
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_BIOS");
ManagementObjectSearcher BoisInfo = new ManagementObjectSearcher(scope, query);
foreach (ManagementObject mo in BoisInfo.Get())
{
string StrManufactureDate = mo["ReleaseDate"].ToString().Substring(0, 8);
DateTime DT = DateTime.ParseExact(StrManufactureDate, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
HInfor.ManufactureDate = String.Format("{0:d}", DT);
}
}
catch (Exception e) {
}
ReturnStrJson = JsonSerializer.Serialize(HInfor);
return ReturnStrJson;
}
}
需要添加引用：
using Microsoft.Win32;
using System.Management;
using System.Text.Json;
using System.Net.NetworkInformation;调用比较简单：
string JsonStr;
//硬件信息
JsonStr = HardwareInformation.GetJsonStr();
var ObjHardware = JsonSerializer.Deserialize<Dictionary<string, object>>(JsonStr);
ListBox listbox1 = tabControl1.TabPages[0].Controls["listbox1"] as ListBox;
listbox1.Items.Add("主板："+ ObjHardware["MainboardName"]);
listbox1.Items.Add("内存：" + ObjHardware["MemorySize"]);
listbox1.Items.Add("硬盘：" + ObjHardware["HarddiskSize"]);
listbox1.Items.Add("显卡：" + ObjHardware["VideocardName"]);
listbox1.Items.Add("声卡：" + ObjHardware["SoundcardName"]);
listbox1.Items.Add("网卡：" + ObjHardware["NetworkcardName"]);
listbox1.Items.Add("计算机生产商：" + ObjHardware["ManufacturerName"]);
listbox1.Items.Add("计算机生产日期：" + ObjHardware["ManufactureDate"]);使用的是Visual Studio 2022 社区版，后面再进行优化。
