怎么获取CPU和内存相关信息（最好有源码）

如何获取CPU和内存相关信息（最好有源码）
如何获得内存的CPU的使用量以及每个进程的CPU的使用量
如何获得当前计算机的物理内存大小以及使用的物理内存的使用量
最好有源码

[解决办法]
Process名字替换掉_Total可以得到相应进程的cpu使用

C# code

public partial class Form1 : Form    {        PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", [color=#FF0000]"_Total"[/color]);         public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            double cpu = getCurrentCpuUsage();            double Freemem = getAvailableRAM();            double usedMem = getCommitedRAM();        }        public double getCurrentCpuUsage()        {             return cpuCounter.NextValue();        }         /*         Call this method every time you need to get         the amount of the available RAM in Mb         */         public double getAvailableRAM()        {                   PerformanceCounter ramCounter = new PerformanceCounter("Memory", "Available Bytes");            return ramCounter.NextValue();         }         /*         Call this method every time you need to get         the amount of the available RAM in Mb         */         public double  getCommitedRAM()        {            PerformanceCounter ramCounter = new PerformanceCounter("Memory", "Committed Bytes");            return ramCounter.NextValue();        }     }

您只需要在VB.NET中加入PerformanceCounter组件,并把该组件的categoryname 设置为processor,其他属性就按照你需要的选择即可.当然,不要忘记把machinename设置为想要监视的机器名(不设置就是本机).
