我有这个代码：

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 DannyGeneral;


namespace CpuUsage
{
    public partial class Form1 : Form
    {
        private List<float> processValues;
        private bool alreadyRun;
        private DateTime dt;
        private DateTime dt1;
        private PerformanceCounter theCPUCounter;
        private PerformanceCounter theMemCounter;
        private PerformanceCounter specProcessCPUCounter;
        private float cpuUsage;
        private float memUsage;
        private List<float> Values;

        public Form1()
        {
            InitializeComponent();

            processValues = new List<float>();
            alreadyRun = false;
            dt = DateTime.Now;


            Values = new List<float>();
                theCPUCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
                theMemCounter = new PerformanceCounter("Memory", "Available MBytes");
                specProcessCPUCounter = new PerformanceCounter("Process", "% Processor Time", Process.GetCurrentProcess().ProcessName);



        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            memUsage = theMemCounter.NextValue();
            label1.Text = memUsage.ToString();
            Logger.Write("Memory Usage   " + memUsage.ToString());
            cpuUsage = this.theCPUCounter.NextValue();
            label2.Text = cpuUsage.ToString();
            Logger.Write("Cpu Usage   " + this.cpuUsage.ToString());
            Values.Add(cpuUsage);
            isProcessRunning();
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            dt1 = DateTime.Now;
            float Maximum = Values.Max();
            float Minimum = Values.Min();
            float Average = Values.Average();
            string t = string.Format("Maximum --- {0} , Minimum --- {1} , Average --- {2}", Maximum, Minimum, Average);
            Logger.Write(t);



            TimeSpan ts = (dt1 - dt);
            string time = ts.ToString(@"hh\:mm\:ss");
            Logger.Write("Time The Program Was Running ---   " + time);


        }

        private void isProcessRunning()
        {

                Process[] proclist = Process.GetProcessesByName("BFBC2Game");

                    if (proclist.Length > 0)
                    {
                        if (alreadyRun == false)
                        {
                            Logger.Write("Bfbc2 Started");
                            alreadyRun = true;
                        }
                    }
                    else
                    {
                        if (alreadyRun == true)
                        {
                            Logger.Write("Bfbc2 Exited");
                            alreadyRun = false;
                        }
                    }

        }

    }
}

我刚刚添加了一个新列表：processValues。我想要做的是，当我退出进程时，例如在这种情况下：BFBC2Game 它会从进程开始到结束时为我写入记录器 Max() Min() 和 Average()。

问题是该过程可能在程序运行几分钟并已经记录了一些信息后开始。我只想在过程开始和结束的时间之间获得最大最小值和平均值。

因此，当我关闭表单时，程序退出记录器文本文件中的程序，我现在看到最后：

8/31/2012--12:18 AM ==> Maximum --- 42.05113 , Minimum --- 0 , Average --- 13.19243
8/31/2012--12:18 AM ==> Time The Program Was Running ---   00:00:49

当进程开始和退出时，我看到中间的某个地方：

8/31/2012--12:17 AM ==> Memory Usage   4435
8/31/2012--12:17 AM ==> Cpu Usage   5.57648
8/31/2012--12:17 AM ==> Bfbc2 Started
8/31/2012--12:17 AM ==> Memory Usage   4412
8/31/2012--12:17 AM ==> Cpu Usage   15.38422
8/31/2012--12:17 AM ==> Bfbc2 Exited
8/31/2012--12:18 AM ==> Memory Usage   4432
8/31/2012--12:18 AM ==> Cpu Usage   13.26883

现在我希望当我退出应用程序时它会在文件末尾写下这样的内容：

8/31/2012--12:18 AM ==> Bfbc2 Started at 8/31/2012--12:17 AM
8/31/2012--12:19 AM ==> Maximum --- 42.05113 , Minimum --- 0 , Average --- 13.19243
8/31/2012--12:19 AM ==> Bfbc2 Exited at 8/31/2012--12:17 AM

所以我会知道当进程开始和结束时查看文件的末尾，以及进程运行时间的最小值和平均值混合值是多少。

您可以使用 System.Diagnostics.Stopwatch 类。这是一个示例代码。这是指向相应 Microsoft 文档的链接。

using System;
using System.Diagnostics;

class Program
{
    static void Main(string[] args)
    {
        int[] array = new int[] { 4, 2, 5, 1, 3 };
        Stopwatch clock = Stopwatch.StartNew();
        SortRecursivly(array);
        clock.Stop();
        Console.WriteLine($"Array sorted in {clock.ElapsedMilliseconds}ms");
    }
}
