C#下实现Ping操作 - (第四十一讲)

视频讲解如下：

        这是一种在C#环境下实现Ping的一种方法，程序执行过程中，会在exe所在的目录下生成一个log的目录，记录周期为每小时一个log文件，程序采用bat脚本文件进行启动，exe的程序名称为“ConsoleApp.exe”，bat脚本文件内容如下：

ConsoleApp.exe 127.0.0.1 3

其中第一个参数是需要Ping的IP，第二个参数是Ping的间隔，单位是秒。

执行效果如下：

源代码如下：

using System;
using System.IO;
using System.Net.NetworkInformation;
using System.Threading;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            if(args != null && args.Length == 2)
            {
                Console.WriteLine("IP:" + args[0]);
                Console.WriteLine("Time:" + args[1]);
                MyPing(args[0], int.Parse(args[1]));
            }
            else Environment.Exit(0);
        }

        /// <summary>
        /// 时间差计算
        /// </summary>
        /// <param name="tim"></param>
        /// <returns></returns>
        public static long TimeSecondDif(DateTime tim)
        {
            return (DateTime.Now.Ticks - tim.Ticks) / 10000000;
        }

        /// <summary>
        /// 另一种保存文件的方式（追加写）
        /// </summary>
        /// <param name="data"></param>
        public static void WriteFile(string data)
        {
            try
            {
                Console.WriteLine(data);
                string path = Environment.CurrentDirectory + @"\log\";
                if (!Directory.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }
                string FileName = path + DateTime.Now.ToString("yyyyMMddhh") + "_log.txt";
                using (StreamWriter file = new StreamWriter(FileName, true))
                {
                    file.WriteLine(data);
                    file.Close();
                }
            }
            catch { }
        }
        public static void MyPing(string ip, int sec)
        {
            WriteFile($"{DateTime.Now}：启动");
            DateTime time = DateTime.Now;
            while (true)
            {
                try
                {
                    Thread.Sleep(500);
                    if (TimeSecondDif(time) > sec)
                    {
                        time = DateTime.Now;
                        DateTime dt = DateTime.Now;
                        PingReply reply = new Ping().Send(ip, 1000);
                        if (reply.Status == IPStatus.Success)
                        {
                            string s = $"{DateTime.Now}：来自 {reply.Address} 的回复：字节={reply.Buffer.Length} 时间={reply.RoundtripTime}ms TTL={reply.Options.Ttl}";
                            WriteFile(s);
                        }
                        else
                        {
                            string s = $"{DateTime.Now}：来自 {reply.Address} 的回复：无法访问目标主机。";
                            WriteFile(s);
                        }
                    }
                }
                catch (Exception e)
                {
                    WriteFile($"程序错误:{e.Message}");
                }
            }
        }
    }
