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 string OSName { get; set; }
        public string OSType { get; set; }

            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。
