PingReply.Status 속성

정의

네임스페이스:

System.Net.NetworkInformation

어셈블리:

netstandard.dll, System.Net.Ping.dll

Source:

PingReply.cs

ICMP(인터넷 제어 메시지 프로토콜) 에코 요청을 보내고 해당 ICMP 에코 응답 메시지를 수신하려는 시도의 상태를 가져옵니다.

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

속성 값

IPStatus

IPStatus 요청의 결과를 나타내는 값입니다.

예제

다음 코드 예제에서는 클래스를 사용하여 Ping ICMP 에코 요청을 동기적으로 보내고 응답을 표시하는 방법을 보여 줍니다.

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);
            }
        }
    }
}

        0
    | _ ->

설명

값 Status 이 아닌 Success경우 , Options 또는 Buffer 속성에서 RoundtripTime반환된 값을 사용하면 안 됩니다. 및 속성은 RoundtripTime 0을 반환하고 속성은 Options 반환null됩니다.Buffer
