## 实现 ##

新建一个窗体页面，设计布局如下

左边CPU使用是两个Panel,右边是PregressBar，下面是StatusStrip,然后在页面添加一个Timer,

然后修改其代码如下

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    using System.Diagnostics;
    using System.Threading;
    using System.Runtime.InteropServices;
    using System.Management;
    namespace CPU_Detect
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
            Process[] MyProcesses;
            Thread td;
            private void myUser()
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from Win32_Processor");
                foreach (ManagementObject myobject in searcher.Get())
                {
                    tssluse.Text = myobject["LoadPercentage"].ToString()+" %";
                    lblCPU.Text = myobject["LoadPercentage"].ToString() + " %";
                    mheight = Convert.ToInt32(myobject["LoadPercentage"].ToString());
                    if (mheight == 100)
                        panel3.Height = 100;
                    CreateImage();
                    Memory();
                }
            }
    
            private void Memory()
            {
                Microsoft.VisualBasic.Devices.Computer myInfo = new Microsoft.VisualBasic.Devices.Computer();
                //获取物理内存总量
                pbMemorySum.Maximum = Convert.ToInt32(myInfo.Info.TotalPhysicalMemory/1024/1024);
                pbMemorySum.Value = Convert.ToInt32(myInfo.Info.TotalPhysicalMemory / 1024 / 1024);
                lblSum.Text = (myInfo.Info.TotalPhysicalMemory / 1024).ToString();
                //获取可用物理内存总量
                pbMemoryUse.Maximum = Convert.ToInt32(myInfo.Info.TotalPhysicalMemory / 1024 / 1024);
                pbMemoryUse.Value = Convert.ToInt32(myInfo.Info.AvailablePhysicalMemory / 1024 / 1024);
                lblMuse.Text = (myInfo.Info.AvailablePhysicalMemory / 1024).ToString();
                //获取虚拟内存总量
                pbVmemorysum.Maximum = Convert.ToInt32(myInfo.Info.TotalVirtualMemory / 1024 / 1024);
                pbVmemorysum.Value = Convert.ToInt32(myInfo.Info.TotalVirtualMemory / 1024 / 1024);
                lblVinfo.Text = (myInfo.Info.TotalVirtualMemory / 1024).ToString();
                //获取可用虚拟内存总量
                pbVmemoryuse.Maximum = Convert.ToInt32(myInfo.Info.TotalVirtualMemory / 1024 / 1024);
                pbVmemoryuse.Value = Convert.ToInt32(myInfo.Info.AvailableVirtualMemory/ 1024 / 1024);
                lblVuse.Text = (myInfo.Info.AvailableVirtualMemory / 1024).ToString();
            }
            private void Form1_Load(object sender, EventArgs e)
            {
                CheckForIllegalCrossThreadCalls = false;
                MyProcesses = Process.GetProcesses();
                tsslNum.Text = MyProcesses.Length.ToString();
                myUser();
            }
    
            private void timer1_Tick(object sender, EventArgs e)
            {
                MyProcesses = Process.GetProcesses();
                tsslNum.Text = MyProcesses.Length.ToString();
                td = new Thread(new ThreadStart(myUser));
                td.Start();
            }
    
            private void Form1_FormClosed(object sender, FormClosedEventArgs e)
            {
                if (td != null)
                {
                    td.Abort();
                }
            }
            int mheight = 0;
            private void CreateImage()
            {
                int i=panel3.Height/100;
                Bitmap image = new Bitmap(panel3.Width,panel3.Height);
                //创建Graphics类对象
                Graphics g = Graphics.FromImage(image);
                g.Clear(Color.Green);
                SolidBrush mybrush = new SolidBrush(Color.Lime);
                g.FillRectangle(mybrush,0,panel3.Height-mheight*i,26,mheight*i);
                panel3.BackgroundImage = image;
    
            }
        }
    }
