PingReply.Status プロパティ

定義

ICMP (インターネット制御メッセージ プロトコル) エコー要求の送信と、対応する ICMP エコー応答メッセージの受信の処理のステータスを取得します。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

プロパティ値

IPStatus

要求の結果を示す IPStatus 値。An IPStatus value indicating the result of the request.

次のコード例は、クラスを使用して Ping ICMP エコー要求を同期的に送信し、応答を表示する方法を示しています。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);
            }
        }
    }
}

注釈

の値がでない場合は、 Status Success RoundtripTimeOptions またはプロパティによって返される値を使用しないでください BufferIf the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. RoundtripTimeプロパティと Buffer プロパティは0を返し、プロパティはを Options 返し null ます。The RoundtripTime and Buffer properties will return zero, and the Options property will return null.
