在編程過程中，我們經(jīng)常需要獲取電腦的相關(guān)信息，例如操作系統(tǒng)版本、CPU信息、內(nèi)存大小等，本文將介紹如何在C中獲取這些屬性。
獲取操作系統(tǒng)版本
要獲取操作系統(tǒng)版本，可以使用System.Environment類的OSVersion屬性，以下是一個簡單的示例：
using System;
class Program
{
static void Main()
{
var osVersion = Environment.OSVersion;
Console.WriteLine("操作系統(tǒng)版本：");
Console.WriteLine($"Major Version: {osVersion.MajorVersion}");
Console.WriteLine($"Minor Version: {osVersion.MinorVersion}");
Console.WriteLine($"Build Number: {osVersion.BuildNumber}");
Console.WriteLine($"Revision: {osVersion.Revision}");
}
}
獲取CPU信息
要獲取CPU信息，可以使用System.Management命名空間下的ManagementObjectSearcher類，以下是一個簡單的示例：
using System;
using System.Management;
class Program
{
static void Main()
{
var cpuInfo = GetCpuInfo();
Console.WriteLine("CPU信息：");
Console.WriteLine($"制造商： {cpuInfo["Manufacturer"]}");
Console.WriteLine($"型號： {cpuInfo["Name"]}");
Console.WriteLine($"核心數(shù)： {cpuInfo["NumberOfCores"]}");
Console.WriteLine($"線程數(shù)： {cpuInfo["NumberOfLogicalProcessors"]}");
}
private static Dictionary GetCpuInfo()
{
var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
var collection = searcher.Get();
var cpuInfo = new Dictionary();
foreach (var item in collection)
{
cpuInfo["Manufacturer"] = item["Manufacturer"];
cpuInfo["Name"] = item["Name"];
cpuInfo["NumberOfCores"] = item["NumberOfCores"];
cpuInfo["NumberOfLogicalProcessors"] = item["NumberOfLogicalProcessors"];
break; // 只獲取第一個CPU信息即可，后續(xù)可以添加其他屬性獲取
}
return cpuInfo;
}
}
獲取內(nèi)存大小(以字節(jié)為單位)
要獲取內(nèi)存大小，可以使用System.Management命名空間下的ManagementObjectSearcher類，以下是一個簡單的示例：
using System;
using System.Management;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Collections.Generic;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using Microsoft.Win32; // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用DllImport("shell32.dll") public static class SHELL32; // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用DllImport("kernel32.dll") public static class GetSystemInfoEx; // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用DllImport("psapi", CharSet = CharSet.Auto)] public static class Psapi; [StructLayout(LayoutKind.Sequential)] public struct MEMORYSTATUSEX; public enum MemoryType { Private = 0, Shared = NonPaged, Total = NonPaged + Shared }; public struct PROCESS_MEMORY_COUNTERS_EX; public struct SHELL_MEMORY_COUNTERS; public static void Main() => Task.Run(async () => await GetMemorySizeAsync()).Wait(); async Task GetMemorySizeAsync() => ulong memorySize = default; try // Windows Vista and later using SHELL32::SHGetMemInfo(out SHELL_MEMORY_COUNTERS shellMemoryCounters); // Windows XP using GetSystemInfoEx::GetSystemInfoEx(out MEMORYSTATUSEX memoryStatusEx); using (var process = Process.GetCurrentProcess()) using (var psutilProcessMemoryCounters = process?.SafeMemoryUsage()) using (var systemMemoryStatusEx = new MEMORYSTATUSEX()) // Windows Vista and later systemMemoryStatusEx = new MEMORYSTATUSEX(); // Windows XP systemMemoryStatusEx = GetSystemInfoEx(); if (psutilProcessMemoryCounters != null) memorySize += psutilProcessMemoryCounters.PrivateUsage Marshal.SizeOf(); if (systemMemoryStatusEx != null) memorySize += systemMemoryStatusEx.WorkingSetSize; if (shellMemoryCounters != null) memorySize += shellMemoryCounters.PrivateUsage * Marshal.SizeOf(); return memorySize; catch (Exception ex) { Console.WriteLine($"無法獲取內(nèi)存大小{ex}"); return default; } // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("psapi", CharSet = CharSet.Auto)] public static extern bool GetProcessMemoryInfo(IntPtr hProcess, out PROCESS_MEMORY_COUNTERS_EX pmc, int cb); [StructLayout(LayoutKind.Sequential)] public struct PROCESS_MEMORY_COUNTERS_EX {}; [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS; [StructLayout(LayoutKind.Sequential)] public struct PSAPI_WORKING_SET_EX {}; // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("psapi", CharSet = CharSet.Auto)] public static extern bool GetProcessMemoryInfo(IntPtr hProcess, out SHELL_MEMORY_COUNTERS memCounters, int size); [DllImport("kernel32")] public static extern UInt64 GlobalMemoryStatusEx([Out] out MEMORYSTATUSEX lpBuffer); [StructLayout(LayoutKind.Sequential)] public struct MEMORYSTATUSEX // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("kernel32")] public static extern UInt64 GlobalMemoryStatusEx([Out] out MEMORYSTATUSEX[] buffer, UInt32 length); [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("psapi", CharSet = CharSet.Auto)] public static extern bool GetProcessMemoryInfo(IntPtr hProcess, out PSAPI_WORKING_SET_EX psinfo, int size); [StructLayout(LayoutKind.Sequential)] public struct PSAPI_WORKING_SET_EX // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("psapi", CharSet = CharSet.Auto)] public static extern bool GetProcessMemoryInfo(IntPtr hProcess, out SHELL_MEMORY_COUNTERS shmemCounters, int size); [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動添加引用[DllImport("psapi", CharSet = CharSet.Auto)] public static extern bool GetProcessMemoryInfo(IntPtr hProcess, out SHELL_MEMORY_COUNTERS shmemCounters); [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動寫代碼直接使用[DllImport("kernel32")] public static extern UInt64 GlobalMemoryStatusEx([Out] out long lTotalPhys, [Out] out long lAvailPhys, [Out] out long lTotalPageFile, [Out] out long lAvailPageFile); [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動寫代碼直接使用[DllImport("kernel32")] public static extern UInt64 GlobalMemoryStatusEx2([Out] out long lTotalPhys, [Out] out long lAvailPhys, [Out] out long lTotalPageFile, [Out] out long lAvailPageFile); [StructLayout(LayoutKind.Sequential)] public struct SHELL_MEMORY_COUNTERS // 需要安裝NuGet包Microsoft.WindowsAPICodePack-Shell,或者手動寫代碼直接使用[Out][StructLayout(LayoutKind。
