以编程方式ping到远程服务器 [英] Programmatically ping to remote server

问题描述

你好，

我想通过我的c#.net应用程序ping远程服务器.并希望在没有回复的情况下弹出消息.

我在外壳命令上进行了一些R&D尝试.但是没有成功.我想我需要制作BAT文件来捕获shell命令的输出.

现在，我正在考虑使用TCP-IP编程进行相同的操作.我的意思是说，我想以编程方式"对远程服务器执行ping操作.

Hello,

I want to ping a remote server through my c# .net application. And want to pop up the message in case of no reply.

I tried it with some R & D on shell commands. But was unsuccessful. I think I need to make BAT file to catch the output of the shell command.

Now I am thinking of doing the same with using TCP-IP programming. I mean to say, I want to make a ping to the remote server "pro grammatically"..

Any help please??

using System.Net;
using System.Net.NetworkInformation;
using System.ComponentModel;
using System.Threading;
using System.IO;
namespace PingMyServer
{
 public static void Main(string[] args)
        {

                //throw new ArgumentException("Ping needs a host or IP Address.");

            string who = "someserver.anydomain.net";// args[0]; //fqdn or ip of your server"
            AutoResetEvent waiter = new AutoResetEvent(false);

            Ping pingSender = new Ping();

            // When the PingCompleted event is raised,
            // the PingCompletedCallback method is called.
            pingSender.PingCompleted += new PingCompletedEventHandler(PingCompletedCallback);

            // Create a buffer of 32 bytes of data to be transmitted.
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
            byte[] buffer = Encoding.ASCII.GetBytes(data);

            // Wait 12 seconds for a reply.
            int timeout = 12000;

            // Set options for transmission:
            // The data can go through 64 gateways or routers
            // before it is destroyed, and the data packet
            // cannot be fragmented.
            PingOptions options = new PingOptions(64, true);

            Console.WriteLine("Time to live: {0}", options.Ttl);

            // Send the ping asynchronously.
            // Use the waiter as the user token.
            // When the callback completes, it can wake up this thread.
            pingSender.SendAsync(who, timeout, buffer, options, waiter);

            // Prevent this example application from ending.
            // A real application should do something useful
            // when possible.
            waiter.WaitOne();
            Console.WriteLine("Ping example completed.");

                ((AutoResetEvent)e.UserState).Set();
            }

            PingReply reply = e.Reply;

            DisplayReply(reply);

                Console.WriteLine("Buffer size: {0}", reply.Buffer.Length);
            }
        }
}

使用Ping和PingReply类
