获取计算机内部信息 - ComputerInfoHelper

　　电脑有许多信息，如名称、CPU 和硬盘容量等，整理一个 Helper 来获取，下面目前只整理了一个方法，获取其它信息的方法类似。

一、代码

　　ComputerInfoHelper.cs

using System;using System.Linq;using System.Management;using Wen.Helpers.Common.Computer.Config;namespace Wen.Helpers.Common.Computer{    ///     /// 计算机信息助手类    /// 
    public class ComputerInfoHelper    {        ///         /// 获取硬盘容量汇总        /// 
        public static long GetTotalDiskSize()        {            try            {                var diskDriveManagement = new ManagementClass(WmiPath.DiskDrive);                var diskDriveManagementInstances = diskDriveManagement.GetInstances();                return diskDriveManagementInstances.OfType
     
      ()                    .Select(managementObject => Convert.ToInt64(managementObject[ManagementBaseObjectPropertyName.Size]))                    .Aggregate
      
       (0, (current, diskSize) => diskSize + current);            }            catch(Exception e)            {                Console.WriteLine(e);                throw;            }        }    }}

　　ManagementBaseObjectPropertyName.cs

namespace Wen.Helpers.Common.Computer.Config{    public class ManagementBaseObjectPropertyName    {        ///         /// 名称        /// 
        public const string ComputerName = "Name";        ///         /// 显卡芯片        /// 
        public const string VideoProcessor = "VideoProcessor";        ///         /// 显存大小        /// 
        public const string AdapterRam = "AdapterRAM";        ///         /// 分辨率宽        /// 
        public const string ScreenWidth = "ScreenWidth";        ///         /// 分辨率高        /// 
        public const string ScreenHeight = "ScreenHeight";        ///         /// 电脑型号        /// 
        public const string Version = "Version";        ///         /// 硬盘容量        /// 
        public const string Size = "Size";        ///         /// 内存容量        /// 
        public const string Capacity = "Capacity";        ///         /// cpu 核心数        /// 
        public const string NumberOfCores = "NumberOfCores";    }}

　　WmiPath.cs

namespace Wen.Helpers.Common.Computer.Config{    public class WmiPath    {        ///         /// 内存        /// 
        public const string PhysicalMemory = "Win32_PhysicalMemory";        ///         /// cpu        /// 
        public const string Processor = "Win32_Processor";        ///         /// 硬盘        /// 
        public const string DiskDrive = "win32_DiskDrive";        ///         /// 电脑型号        /// 
        public const string ComputerSystemProduct = "Win32_ComputerSystemProduct";        ///         /// 分辨率        /// 
        public const string DesktopMonitor = "Win32_DesktopMonitor";        ///         /// 显卡        /// 
        public const string VideoController = "Win32_VideoController";        ///         /// 操作系统        /// 
        public const string OperatingSystem = "Win32_OperatingSystem";    }}

二、测试

　　1.电脑硬盘信息

　　2.我的电脑中的硬盘信息

　　3.测试代码

　　4.输出结果：

　　所有硬盘及 U 盘和存储卡，因生产厂家的计算方式和操作系统的计算方式不一样，前者按 1MB = 1000KB 计算，后者按 1MB = 1024KB 计算，所以，实际在电脑中看到的容量会与厂商标称的容量有一定的差异，其中规律为 1G = 0.93G (约等于)，比如 100G，实际为 100G * 0.93 = 93G ，具体容量可参考此公式计算。
