要关注几个类 PerformanceCounter 用来针对cpu  ；ComputerInfo 用来针对内存

using Microsoft.VisualBasic.Devices;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CpuAndMemory
{
    class Program
    {
        //PerformanceCounter 性能计数器
        public static PerformanceCounter cpu;

        //来自程序集 Microsoft.VisualBasic.dll 手动引用
        public static ComputerInfo cInfo;
        static void Main(string[] args)
        {
            cpu = new PerformanceCounter("Processor", "% Processor Time", "_Total");

            //---------------内存相关---------------
            cInfo = new ComputerInfo();
            Console.WriteLine("当前计算机的总内存大小为"+cInfo.TotalPhysicalMemory/1024/1024+"G");
            Console.WriteLine("当前计算机的虚拟内存大小为："+cInfo.TotalVirtualMemory / 1024 / 1024 + "G");
            Console.WriteLine("当前计算机的虚拟内存大小为：" + cInfo.TotalVirtualMemory);
            Console.WriteLine("当前计算机的可用物理内存大小为：" + cInfo.AvailablePhysicalMemory);
            Console.WriteLine("当前计算机的可用虚拟内存大小为：" + cInfo.AvailableVirtualMemory);
            //---------------内存相关---------------
            Console.ReadKey();
        }
    }
}
