如何自动启动和停止 influxdata 进程？

Question

我最近使用设置了我的第一个 influxdb

https://www.influxdata.com/blog/getting-started-with-c-and-influxdb/

本教程。 我让应用程序运行并更改了程序以满足我的需要。 我知道您可以通过在 CMD 中键入“do.net run”来启动该过程，并通过在 CMD 中按 ctrl + c 来停止它。

但是如何通过 c# 代码自动启动和终止进程呢？

我希望该进程在被另一个 Programm 调用时运行，然后在 24 小时后终止。

提前致谢。

您的问题应该简化为如何启动和安排进程关闭。

可以使用定时器 class和ProcessStartInfo.CreateNoWindow class 。

在我的演示中， open(button)将打开path中的.txt文件。

close(button)将开始 5 秒倒计时以关闭notepad程序。

您可以根据需要更改它。

这里使用的是.net 4.8框架winform。

当然，您也可以使用控制台应用程序来完成此操作。

下面是我的代码：

using System;
using System.Diagnostics;
using System.IO;
using System.Timers;
using System.Windows.Forms;

namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private static System.Timers.Timer aTimer;

        private void button1_Click(object sender, EventArgs e)
        {
            StartApp(@"C:\Users\Administrator\Desktop");
        }
        /// <summary>
        /// Start the process
        /// </summary>
        /// <param name="ArrayFolderPath">Need to open the path of the process folder, multiple paths are separated by ','; eg:d:\test,e:\temp</param>
        private void StartApp(string ArrayFolderPath)
        {
            string[] foldersNamePath = ArrayFolderPath.Split(',');
            foreach (string folderNamePath in foldersNamePath)
            {
                GetFolderApp(folderNamePath);
            }
        }

        /// <summary>
        /// Recursively traverse all exe files in the folder, this method can be further extended to other suffix files
        /// </summary>
        /// <param name="folderNamePath">Folder path</param>
        private void GetFolderApp(string folderNamePath)
        {
            string[] foldersPath = Directory.GetDirectories(folderNamePath);
            foreach (string folderPath in foldersPath)
            {
                GetFolderApp(folderPath);
            }

            string[] filesPath = Directory.GetFiles(folderNamePath);
            foreach (string filePath in filesPath)
            {
                FileInfo fileInfo = new FileInfo(filePath);

                //Open the file with the suffix .txt
                if (fileInfo.Extension.Equals(".txt"))
                {
                    Process.Start(filePath);
                }
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            SetTimer();
        }
        private static void SetTimer()
        {
            // Create a timer with a two second interval.
            aTimer = new System.Timers.Timer(5000);
            // Hook up the Elapsed event for the timer. 
            aTimer.Elapsed += OnTimedEvent;
            aTimer.AutoReset = true;
            aTimer.Enabled = true;
        }

        private static void OnTimedEvent(Object source, ElapsedEventArgs e)
        {
            CloseApp("Notepad");
        }

        /// <summary>
        /// Close the application
        /// </summary>
        /// <param name="ArrayProcessName">The application names are separated by ','</param>
        private static void CloseApp(string ArrayProcessName)
        {
            string[] processName = ArrayProcessName.Split(',');
            foreach (string appName in processName)
            {
                Process[] localByNameApp = Process.GetProcessesByName(appName);//Get all processes with program name
                if (localByNameApp.Length > 0)
                {
                    foreach (var app in localByNameApp)
                    {
                        if (!app.HasExited)
                        {
                            app.Kill();//close the process
                        }
                    }
                }
            }
        }
    }
}

Output：
