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)
{
//if (args.Length == 0)
//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);
Console.WriteLine("Don't fragment: {0}", options.DontFragment);
// 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.");
Console.WriteLine();
}
private static void PingCompletedCallback(object sender, PingCompletedEventArgs e)
{
// If the operation was canceled, display a message to the user.
if (e.Cancelled)
{
Console.WriteLine("Ping canceled.");
// Let the main thread resume.
// UserToken is the AutoResetEvent object that the main thread
// is waiting for.
((AutoResetEvent)e.UserState).Set();
}
// If an error occurred, display the exception to the user.
if (e.Error != null)
{
Console.WriteLine("Ping failed:");
Console.WriteLine(e.Error.ToString());
// Let the main thread resume.
((AutoResetEvent)e.UserState).Set();
}
PingReply reply = e.Reply;
DisplayReply(reply);
// Let the main thread resume.
((AutoResetEvent)e.UserState).Set();
}
public static void DisplayReply(PingReply reply)
{
if (reply == null)
return;
Console.WriteLine("ping status: {0}", reply.Status);
if (reply.Status == IPStatus.Success)
{
Console.WriteLine("Address: {0}", reply.Address.ToString());
Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
