PingReply.Status Propriedade
Definição
Obtém o status de uma tentativa de enviar uma solicitação de eco do protocolo ICMP e receber a mensagem de resposta de eco ICMP correspondente.Gets the status of an attempt to send an Internet Control Message Protocol (ICMP) echo request and receive the corresponding ICMP echo reply message.
public:
property System::Net::NetworkInformation::IPStatus Status { System::Net::NetworkInformation::IPStatus get(); };
public System.Net.NetworkInformation.IPStatus Status { get; }
member this.Status : System.Net.NetworkInformation.IPStatus
Public ReadOnly Property Status As IPStatus
Valor da propriedade
Um valor IPStatus que indica o resultado da solicitação.An IPStatus value indicating the result of the request.
Exemplos
O exemplo de código a seguir demonstra Ping como usar a classe para enviar uma solicitação de eco ICMP de forma síncrona e exibir a resposta.The following code example demonstrates using Ping class to send an ICMP echo request synchronously and display the response.
#using <System.dll>
using namespace System;
using namespace System::Net;
using namespace System::Net::NetworkInformation;
using namespace System::Text;
// args[1] can be an IPaddress or host name.
int main()
{
array<String^>^args = Environment::GetCommandLineArgs();
Ping ^ pingSender = gcnew Ping;
PingOptions ^ options = gcnew PingOptions;
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options->DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
String^ data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
array<Byte>^buffer = Encoding::ASCII->GetBytes( data );
int timeout = 120;
PingReply ^ reply = pingSender->Send( args[ 1 ], timeout, buffer, options );
if ( reply->Status == IPStatus::Success )
{
Console::WriteLine( "Address: {0}", reply->Address->ToString() );
Console::WriteLine( "RoundTrip time: {0}", reply->RoundtripTime );
Console::WriteLine( "Time to live: {0}", reply->Options->Ttl );
Console::WriteLine( "Don't fragment: {0}", reply->Options->DontFragment );
Console::WriteLine( "Buffer size: {0}", reply->Buffer->Length );
}
}
using System;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;
namespace Examples.System.Net.NetworkInformation.PingTest
{
public class PingExample
{
// args[0] can be an IPaddress or host name.
public static void Main (string[] args)
{
Ping pingSender = new Ping ();
PingOptions options = new PingOptions ();
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options.DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
byte[] buffer = Encoding.ASCII.GetBytes (data);
int timeout = 120;
PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
if (reply.Status == IPStatus.Success)
{
Console.WriteLine ("Address: {0}", reply.Address.ToString ());
Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
}
}
}
}
Comentários
Se o valor de Status não for Success , você não deverá usar os valores retornados pelas RoundtripTime Propriedades, Options ou Buffer .If the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. As RoundtripTime Buffer Propriedades e retornarão zero e a Options propriedade será retornada null .The RoundtripTime and Buffer properties will return zero, and the Options property will return null.
