利用C#实现获取与监控电脑系统信息

using System;
using System.Diagnostics;
using System.Management;

class Program
{
    static void Main()
    {
        // 获取操作系统信息
        OperatingSystem os = Environment.OSVersion;
        Console.WriteLine($"操作系统: {os.VersionString}");

        // 获取当前进程信息
        Process currentProcess = Process.GetCurrentProcess();
        Console.WriteLine($"当前进程ID: {currentProcess.Id}");

        // 获取所有进程信息
        Process[] processes = Process.GetProcesses();
        foreach (Process process in processes)
        {
            Console.WriteLine($"进程名: {process.ProcessName}, ID: {process.Id}");
        }

        // 使用WMI获取CPU信息
        SelectQuery query = new SelectQuery("Win32_Processor");
        using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
        {
            foreach (ManagementObject obj in searcher.Get())
            {
                Console.WriteLine($"CPU描述: {obj["Description"]}");
            }
        }
    }
}

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        // 创建性能计数器实例
        PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
        PerformanceCounter memCounter = new PerformanceCounter("Memory", "Available MBytes");

        // 初始化计数器（第一次调用时通常需要忽略返回值）
        cpuCounter.NextValue();
        memCounter.NextValue();
        System.Threading.Thread.Sleep(1000); // 等待一秒以获取准确的读数

        // 读取计数器值
        float cpuUsage = cpuCounter.NextValue() / Environment.ProcessorCount;
        float availableMemory = memCounter.NextValue();

        Console.WriteLine($"CPU使用率: {cpuUsage:P}");
        Console.WriteLine($"可用内存: {availableMemory} MB");
    }
